I-405 EXPRESS TOLL LANES 45 MONTH UPDATE OCTOBER 2015 ndashJUNE 2019
EXECUTIVE SUMMARY The express toll lanes are continuing to meet the three goals that the Washington State Department of Transportation set for them
GOAL 1 Provide a choice to people bull 59000 vehicles use the express toll lanes each day 39000 drivers choose to pay a toll and 20000 vehicles drive toll-free
bull Drivers pay an average toll rate of $479 for peak period peak direction trips
GOAL 2 Provide a faster more predictable trip Drivers saved an average of 11 minutes using the express toll lanes compared to the general purpose lanes on trips between Bellevue and Lynnwood during peak periods
I-405 now carries up to 23 percent more vehicles each weekday during the peak periods when compared to before tolling began Using the most recent occupancy data from 2018 I-405 also carries up to 16 percent more people when compared to before tolling began
Even though I-405 is carrying many more vehicles average speeds in the express toll lanes have increased by as much as 17 mph while general purpose lanes have improved by as much as 3 mph compared to pretolling in some areas
Every day 7750 people ride buses in the express toll lanes This is an increase of 9 percent for King County Metro and 2 percent for Community Transit when compared to before tolling began

GOAL 3 Generate revenue to reinvest in the corridor bull In 45 months the express toll lanes generated $995 million in total revenue While $328 million has been used to maintain and operate the lanes the remaining $668 million has been dedicated to be reinvested back into the I-405 Corridor including Complete $115 million for the peak use shoulder lane on northbound I-405 in Bothell Under way Funding for preliminary engineering environmental review processes and construction for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange

Legislative Performance Measures The legislation that authorized the construction and operation of the I-405 express toll lanes requires WSDOT to report quarterly on several performance measures including
bull Whether the express toll lanes generated sufficient revenue to pay for all express toll lane-related operating costs
bull Whether the express toll lanes maintain speeds of 45 miles per hour at least 90 percent of the time during peak periods and any alternate metric determined by the department in conjunction with the federal highway administration Revenue The express toll lanes have consistently generated more revenue than is necessary to fund operational costs During the 2019 spring quarter the express toll lanes generated $93 million in total revenue which was more than enough to cover the $52 million in expenditures This brings the total revenue generated through 45 months of operations to $995 million with the total cost of operating and maintaining the lanes at $328 million
The Legislature specified that net revenue must be used to improve the corridor WSDOT has already reinvested $115 million into the peak use shoulder lane Additional revenue was allocated by the Legislature to fund preliminary engineering and environmental review processes for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange Construction for this

project is scheduled to begin in 2021 with an anticipated three to four year construction period
Speed reliability While the express toll lanes have reduced travel times and increased speeds during peak periods in most sections of the corridor some sections have fallen short of the second legislative performance measure of maintaining speeds of 45 mph or faster 90 percent of the time during peak periods However the southbound dual lane section and the northbound single lane section are both surpassing the 90 percent goal WSDOT reports this measure in six month increments in order to be consistent with reporting to the Federal Highway Administration
Overall the express toll lanes are meeting the speed target 80 percent of the time during peak periods from January 2019 to June 2019 despite the fact that I-405 is carrying up to 23 percent more vehicles each weekday when compared to before tolling began This is a significant improvement compared to the old HOV lanes which only met the goal 62 percent of the time during the same time of year in 2015 before they were turned into express toll lanes
The southbound lanes move at 45 mph 71 percent of the time during peak periods due to a lack of capacity in the single lane section and increasing traffic volumes The northbound lanes met the speed goal 89 percent of the time due to heavy demand between Bellevue and Bothell Percent of peak time periods Express toll lanes Pre-Tolling HOV

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

I-405 EXPRESS TOLL LANES 45 MONTH UPDATE OCTOBER 2015 ndashJUNE 2019
EXECUTIVE SUMMARY The express toll lanes are continuing to meet the three goals that the Washington State Department of Transportation set for them
GOAL 1 Provide a choice to people bull 59000 vehicles use the express toll lanes each day 39000 drivers choose to pay a toll and 20000 vehicles drive toll-free
bull Drivers pay an average toll rate of $479 for peak period peak direction trips
GOAL 2 Provide a faster more predictable trip Drivers saved an average of 11 minutes using the express toll lanes compared to the general purpose lanes on trips between Bellevue and Lynnwood during peak periods
I-405 now carries up to 23 percent more vehicles each weekday during the peak periods when compared to before tolling began Using the most recent occupancy data from 2018 I-405 also carries up to 16 percent more people when compared to before tolling began
Even though I-405 is carrying many more vehicles average speeds in the express toll lanes have increased by as much as 17 mph while general purpose lanes have improved by as much as 3 mph compared to pretolling in some areas
Every day 7750 people ride buses in the express toll lanes This is an increase of 9 percent for King County Metro and 2 percent for Community Transit when compared to before tolling began

GOAL 3 Generate revenue to reinvest in the corridor bull In 45 months the express toll lanes generated $995 million in total revenue While $328 million has been used to maintain and operate the lanes the remaining $668 million has been dedicated to be reinvested back into the I-405 Corridor including Complete $115 million for the peak use shoulder lane on northbound I-405 in Bothell Under way Funding for preliminary engineering environmental review processes and construction for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange

Washington State Department of Transportation
Legislative Performance Measures The legislation that authorized the construction and operation of the I-405 express toll lanes requires WSDOT to report quarterly on several performance measures including
bull Whether the express toll lanes generated sufficient revenue to pay for all express toll lane-related operating costs
bull Whether the express toll lanes maintain speeds of 45 miles per hour at least 90 percent of the time during peak periods and any alternate metric determined by the department in conjunction with the federal highway administration Revenue The express toll lanes have consistently generated more revenue than is necessary to fund operational costs During the 2019 spring quarter the express toll lanes generated $93 million in total revenue which was more than enough to cover the $52 million in expenditures This brings the total revenue generated through 45 months of operations to $995 million with the total cost of operating and maintaining the lanes at $328 million
The Legislature specified that net revenue must be used to improve the corridor WSDOT has already reinvested $115 million into the peak use shoulder lane Additional revenue was allocated by the Legislature to fund preliminary engineering and environmental review processes for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange Construction for this

project is scheduled to begin in 2021 with an anticipated three to four year construction period
Speed reliability While the express toll lanes have reduced travel times and increased speeds during peak periods in most sections of the corridor some sections have fallen short of the second legislative performance measure of maintaining speeds of 45 mph or faster 90 percent of the time during peak periods However the southbound dual lane section and the northbound single lane section are both surpassing the 90 percent goal WSDOT reports this measure in six month increments in order to be consistent with reporting to the Federal Highway Administration
Overall the express toll lanes are meeting the speed target 80 percent of the time during peak periods from January 2019 to June 2019 despite the fact that I-405 is carrying up to 23 percent more vehicles each weekday when compared to before tolling began This is a significant improvement compared to the old HOV lanes which only met the goal 62 percent of the time during the same time of year in 2015 before they were turned into express toll lanes
The southbound lanes move at 45 mph 71 percent of the time during peak periods due to a lack of capacity in the single lane section and increasing traffic volumes The northbound lanes met the speed goal 89 percent of the time due to heavy demand between Bellevue and Bothell Percent of peak time periods Express toll lanes Pre-Tolling HOV

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

I-405 EXPRESS TOLL LANES 45 MONTH UPDATE OCTOBER 2015 ndashJUNE 2019
EXECUTIVE SUMMARY The express toll lanes are continuing to meet the three goals that the Washington State Department of Transportation set for them
GOAL 1 Provide a choice to people bull 59000 vehicles use the express toll lanes each day 39000 drivers choose to pay a toll and 20000 vehicles drive toll-free
bull Drivers pay an average toll rate of $479 for peak period peak direction trips
GOAL 2 Provide a faster more predictable trip Drivers saved an average of 11 minutes using the express toll lanes compared to the general purpose lanes on trips between Bellevue and Lynnwood during peak periods
I-405 now carries up to 23 percent more vehicles each weekday during the peak periods when compared to before tolling began Using the most recent occupancy data from 2018 I-405 also carries up to 16 percent more people when compared to before tolling began
Even though I-405 is carrying many more vehicles average speeds in the express toll lanes have increased by as much as 17 mph while general purpose lanes have improved by as much as 3 mph compared to pretolling in some areas
Every day 7750 people ride buses in the express toll lanes This is an increase of 9 percent for King County Metro and 2 percent for Community Transit when compared to before tolling began

GOAL 3 Generate revenue to reinvest in the corridor bull In 45 months the express toll lanes generated $995 million in total revenue While $328 million has been used to maintain and operate the lanes the remaining $668 million has been dedicated to be reinvested back into the I-405 Corridor including Complete $115 million for the peak use shoulder lane on northbound I-405 in Bothell Under way Funding for preliminary engineering environmental review processes and construction for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange
2
Washington State Department of Transportation
Legislative Performance Measures The legislation that authorized the construction and operation of the I-405 express toll lanes requires WSDOT to report quarterly on several performance measures including
bull Whether the express toll lanes generated sufficient revenue to pay for all express toll lane-related operating costs
bull Whether the express toll lanes maintain speeds of 45 miles per hour at least 90 percent of the time during peak periods and any alternate metric determined by the department in conjunction with the federal highway administration Revenue The express toll lanes have consistently generated more revenue than is necessary to fund operational costs During the 2019 spring quarter the express toll lanes generated $93 million in total revenue which was more than enough to cover the $52 million in expenditures This brings the total revenue generated through 45 months of operations to $995 million with the total cost of operating and maintaining the lanes at $328 million
The Legislature specified that net revenue must be used to improve the corridor WSDOT has already reinvested $115 million into the peak use shoulder lane Additional revenue was allocated by the Legislature to fund preliminary engineering and environmental review processes for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange Construction for this

project is scheduled to begin in 2021 with an anticipated three to four year construction period
Speed reliability While the express toll lanes have reduced travel times and increased speeds during peak periods in most sections of the corridor some sections have fallen short of the second legislative performance measure of maintaining speeds of 45 mph or faster 90 percent of the time during peak periods However the southbound dual lane section and the northbound single lane section are both surpassing the 90 percent goal WSDOT reports this measure in six month increments in order to be consistent with reporting to the Federal Highway Administration
Overall the express toll lanes are meeting the speed target 80 percent of the time during peak periods from January 2019 to June 2019 despite the fact that I-405 is carrying up to 23 percent more vehicles each weekday when compared to before tolling began This is a significant improvement compared to the old HOV lanes which only met the goal 62 percent of the time during the same time of year in 2015 before they were turned into express toll lanes
The southbound lanes move at 45 mph 71 percent of the time during peak periods due to a lack of capacity in the single lane section and increasing traffic volumes The northbound lanes met the speed goal 89 percent of the time due to heavy demand between Bellevue and Bothell Percent of peak time periods Express toll lanes Pre-Tolling HOV

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Washington State Department of Transportation
Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

APPENDIX A LEGISLATIVE PERFORMANCE MEASURES
In its 2011 authorization of the I-405 express toll lanes (RCW 4756880) the Legislature directed WSDOT to monitor and report on seven performance metrics on a quarterly basis
11
Washington State Department of Transportation
Legislative Performance Measures The legislature added reporting requirements during the 2016 budget process detailed in ESHB 2524 209 (7) and in the 2019 budget process in ESHB 1160 209 (8) These subsequent reporting requirements address travel times and volumes for 10 specific travel segments along the I-405 express toll lanes corridor This appendix provides a high-level summary of the travel time data and links to electronic copies of the detailed travel time and volume data The Legislature requested average and at minimum 90th percentile travel times Consistent with WSDOT methodology and the requirements of the proviso this report includes 95th percentile travel times

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Legislative Performance Measures The legislation that authorized the construction and operation of the I-405 express toll lanes requires WSDOT to report quarterly on several performance measures including
bull Whether the express toll lanes generated sufficient revenue to pay for all express toll lane-related operating costs
bull Whether the express toll lanes maintain speeds of 45 miles per hour at least 90 percent of the time during peak periods and any alternate metric determined by the department in conjunction with the federal highway administration Revenue The express toll lanes have consistently generated more revenue than is necessary to fund operational costs During the 2019 spring quarter the express toll lanes generated $93 million in total revenue which was more than enough to cover the $52 million in expenditures This brings the total revenue generated through 45 months of operations to $995 million with the total cost of operating and maintaining the lanes at $328 million
The Legislature specified that net revenue must be used to improve the corridor WSDOT has already reinvested $115 million into the peak use shoulder lane Additional revenue was allocated by the Legislature to fund preliminary engineering and environmental review processes for the I-405 - SR 522 Vicinity to SR 527 Express Toll Lanes Improvement Project which will increase capacity and improve mobility north of the SR 522 interchange Construction for this

project is scheduled to begin in 2021 with an anticipated three to four year construction period
Speed reliability While the express toll lanes have reduced travel times and increased speeds during peak periods in most sections of the corridor some sections have fallen short of the second legislative performance measure of maintaining speeds of 45 mph or faster 90 percent of the time during peak periods However the southbound dual lane section and the northbound single lane section are both surpassing the 90 percent goal WSDOT reports this measure in six month increments in order to be consistent with reporting to the Federal Highway Administration
Overall the express toll lanes are meeting the speed target 80 percent of the time during peak periods from January 2019 to June 2019 despite the fact that I-405 is carrying up to 23 percent more vehicles each weekday when compared to before tolling began This is a significant improvement compared to the old HOV lanes which only met the goal 62 percent of the time during the same time of year in 2015 before they were turned into express toll lanes
The southbound lanes move at 45 mph 71 percent of the time during peak periods due to a lack of capacity in the single lane section and increasing traffic volumes The northbound lanes met the speed goal 89 percent of the time due to heavy demand between Bellevue and Bothell Percent of peak time periods Express toll lanes Pre-Tolling HOV

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

APPENDIX A LEGISLATIVE PERFORMANCE MEASURES
In its 2011 authorization of the I-405 express toll lanes (RCW 4756880) the Legislature directed WSDOT to monitor and report on seven performance metrics on a quarterly basis
11
Washington State Department of Transportation
Legislative Performance Measures The legislature added reporting requirements during the 2016 budget process detailed in ESHB 2524 209 (7) and in the 2019 budget process in ESHB 1160 209 (8) These subsequent reporting requirements address travel times and volumes for 10 specific travel segments along the I-405 express toll lanes corridor This appendix provides a high-level summary of the travel time data and links to electronic copies of the detailed travel time and volume data The Legislature requested average and at minimum 90th percentile travel times Consistent with WSDOT methodology and the requirements of the proviso this report includes 95th percentile travel times
ESHB 2524 209 (7) states
The department must provide quarterly reports to the transportation committees of the legislature on the Interstate 405 express toll lane project performance measures listed in RCW 4756880(4) These reports must include
(a) Information on the travel times and travel time reliability (at a minimum average and 90th percentile travel times) maintained during peak and nonpeak periods in the express toll lanes and general purpose lanes for both the entire corridor and commonly made trips in the corridor including but not limited to northbound from Bellevue to Rose Hill state route number 520 at NE 148th to Interstate 405 at state route number 522 Bellevue to Bothell (both NE 8th to state route number 522 and NE 8th to state route number 527) and a trip internal to the corridor (such as NE 85th to NE 160th) and similar southbound trips
(b) A month-to-month comparison of travel times and travel time reliability for the entire corridor and commonly made trips in the corridor as specified in (a) of this subsection since implementation of the express toll lanes and to the extent available a comparison to the travel times and travel time reliability prior to implementation of the express toll lanes
(c) Total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane (i) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane on this segment of Interstate 405 prior to implementation of the express toll lanes and (ii) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane from month to month since implementation of the express toll lanes and
(d) Underlying congestion measurements that is speeds that are being used to generate the summary graphs provided to be made available in a digital file format
12
Washington State Department of Transportation
ESHB 1160 209 (8) states
(a) The department shall compile monthly data on the number of Washington state patrol enforcement hours on each facility and the percentage of time during peak hours that speeds are at or above forty-five miles per hour on each facility
The Legislature directed WSDOT to examine travel times along specific segments of the I-405 express toll lanes corridor The following table lists these travel segments and their corresponding mileposts A map of the express toll lanes with milepost markers is included for reference at the end of this appendix

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Speed reliability While the express toll lanes have reduced travel times and increased speeds during peak periods in most sections of the corridor some sections have fallen short of the second legislative performance measure of maintaining speeds of 45 mph or faster 90 percent of the time during peak periods However the southbound dual lane section and the northbound single lane section are both surpassing the 90 percent goal WSDOT reports this measure in six month increments in order to be consistent with reporting to the Federal Highway Administration
Overall the express toll lanes are meeting the speed target 80 percent of the time during peak periods from January 2019 to June 2019 despite the fact that I-405 is carrying up to 23 percent more vehicles each weekday when compared to before tolling began This is a significant improvement compared to the old HOV lanes which only met the goal 62 percent of the time during the same time of year in 2015 before they were turned into express toll lanes
The southbound lanes move at 45 mph 71 percent of the time during peak periods due to a lack of capacity in the single lane section and increasing traffic volumes The northbound lanes met the speed goal 89 percent of the time due to heavy demand between Bellevue and Bothell Percent of peak time periods Express toll lanes Pre-Tolling HOV

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Washington State Department of Transportation
Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Washington State Department of Transportation
Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

APPENDIX A LEGISLATIVE PERFORMANCE MEASURES
In its 2011 authorization of the I-405 express toll lanes (RCW 4756880) the Legislature directed WSDOT to monitor and report on seven performance metrics on a quarterly basis
11
Washington State Department of Transportation
Legislative Performance Measures The legislature added reporting requirements during the 2016 budget process detailed in ESHB 2524 209 (7) and in the 2019 budget process in ESHB 1160 209 (8) These subsequent reporting requirements address travel times and volumes for 10 specific travel segments along the I-405 express toll lanes corridor This appendix provides a high-level summary of the travel time data and links to electronic copies of the detailed travel time and volume data The Legislature requested average and at minimum 90th percentile travel times Consistent with WSDOT methodology and the requirements of the proviso this report includes 95th percentile travel times
ESHB 2524 209 (7) states
The department must provide quarterly reports to the transportation committees of the legislature on the Interstate 405 express toll lane project performance measures listed in RCW 4756880(4) These reports must include
(a) Information on the travel times and travel time reliability (at a minimum average and 90th percentile travel times) maintained during peak and nonpeak periods in the express toll lanes and general purpose lanes for both the entire corridor and commonly made trips in the corridor including but not limited to northbound from Bellevue to Rose Hill state route number 520 at NE 148th to Interstate 405 at state route number 522 Bellevue to Bothell (both NE 8th to state route number 522 and NE 8th to state route number 527) and a trip internal to the corridor (such as NE 85th to NE 160th) and similar southbound trips
(b) A month-to-month comparison of travel times and travel time reliability for the entire corridor and commonly made trips in the corridor as specified in (a) of this subsection since implementation of the express toll lanes and to the extent available a comparison to the travel times and travel time reliability prior to implementation of the express toll lanes
(c) Total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane (i) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane on this segment of Interstate 405 prior to implementation of the express toll lanes and (ii) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane from month to month since implementation of the express toll lanes and
(d) Underlying congestion measurements that is speeds that are being used to generate the summary graphs provided to be made available in a digital file format

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Transit Travel Times Since the express toll lanes opened in September 2015 transit ridership has increased by an average of five percent on I-405 During the spring 2019 quarter an average 7750 people used transit routes on the express toll lanes every day WSDOT works with regional transit agencies King County Metro and Community Transit (servicing Snohomish County) to monitor transit performance on the I-405 express toll lanes Both Community Transit and King County Metro operate Sound Transit routes on I-405
King County Metro travel times on I-405 between Bellevue and Lynnwood have improved by 1 to 11 minutes When comparing travel times to pre-tolling conditions daily average travel times for Community Transit showed an improvement for the majority of routes with the exception of Route 424 that travels along I-405 between SR 520 and SR 522 The travel time increase was slightly over a minute The remaining routes have travel time savings of up to 4 minutes

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Revenue Toll revenue is appropriated by the Legislature and monitored by the Office of Financial Management Under existing law I-405 express toll lane revenue must be used to cover facility operations and maintenance costs and any additional revenue is to be invested back in to the corridor
Express toll lane revenue has increased over time due to increasing demand as the number of cars on the road increases However operations costs have remained relatively consistent over the past three years As a result the percentage of revenue going to I-405 improvements has increased each year
In winter 2019 express toll lane revenue decreased due to the snowy weather in February which resulted in less volume on I-405 However the express toll lanes generated more than enough revenue to cover expenses and finances have returned to the previous trend of increasing revenue with relatively stable expenditures

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Washington State Department of Transportation
Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Toll Rates In March 2015 the Washington State Transportation Commission (WSTC) approved a minimum toll rate of 75 cents and a maximum of $10 Toll rates are adjusted by a congestion-based tolling algorithm designed to keep the express toll lanes flowing by adapting the toll rate to match the demand
In the most recent quarter
bull For peak period peak direction trips the average toll rate was $479 a 56 cent increase from last quarter
bull The spring 2019 quarter is returning to the trend of increasing peak period rates 30 2018

Washington State Department of Transportation
Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Maximum Toll WSDOT tracks the instances where the express toll lanes reached $10 In spring 2019 the proportion of drivers who paid the $10 maximum toll rate was
$4 - $bull 85 percent for all tolled trips bull 151 percent for peak period peak direction trips 155 percent of northbound peak period trips paid the $10 toll rate
147 percent of southbound peak period trips paid the $10 toll rate
The chart below represents the percentage of days that the maximum $10 toll rate was displayed during the peak period by quarter For consistency percentages for each quarter are calculated based on the current tolling hours before and after the hours of operation were changed in March 2016

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

APPENDIX A LEGISLATIVE PERFORMANCE MEASURES
In its 2011 authorization of the I-405 express toll lanes (RCW 4756880) the Legislature directed WSDOT to monitor and report on seven performance metrics on a quarterly basis
11
Washington State Department of Transportation
Legislative Performance Measures The legislature added reporting requirements during the 2016 budget process detailed in ESHB 2524 209 (7) and in the 2019 budget process in ESHB 1160 209 (8) These subsequent reporting requirements address travel times and volumes for 10 specific travel segments along the I-405 express toll lanes corridor This appendix provides a high-level summary of the travel time data and links to electronic copies of the detailed travel time and volume data The Legislature requested average and at minimum 90th percentile travel times Consistent with WSDOT methodology and the requirements of the proviso this report includes 95th percentile travel times
ESHB 2524 209 (7) states
The department must provide quarterly reports to the transportation committees of the legislature on the Interstate 405 express toll lane project performance measures listed in RCW 4756880(4) These reports must include
(a) Information on the travel times and travel time reliability (at a minimum average and 90th percentile travel times) maintained during peak and nonpeak periods in the express toll lanes and general purpose lanes for both the entire corridor and commonly made trips in the corridor including but not limited to northbound from Bellevue to Rose Hill state route number 520 at NE 148th to Interstate 405 at state route number 522 Bellevue to Bothell (both NE 8th to state route number 522 and NE 8th to state route number 527) and a trip internal to the corridor (such as NE 85th to NE 160th) and similar southbound trips
(b) A month-to-month comparison of travel times and travel time reliability for the entire corridor and commonly made trips in the corridor as specified in (a) of this subsection since implementation of the express toll lanes and to the extent available a comparison to the travel times and travel time reliability prior to implementation of the express toll lanes
(c) Total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane (i) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane on this segment of Interstate 405 prior to implementation of the express toll lanes and (ii) compared to total express toll lane and total general purpose lane traffic volumes as well as per lane traffic volumes for each type of lane from month to month since implementation of the express toll lanes and
(d) Underlying congestion measurements that is speeds that are being used to generate the summary graphs provided to be made available in a digital file format

Washington State Department of Transportation
ESHB 1160 209 (8) states
(a) The department shall compile monthly data on the number of Washington state patrol enforcement hours on each facility and the percentage of time during peak hours that speeds are at or above forty-five miles per hour on each facility
The Legislature directed WSDOT to examine travel times along specific segments of the I-405 express toll lanes corridor The following table lists these travel segments and their corresponding mileposts A map of the express toll lanes with milepost markers is included for reference at the end of this appendix

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Though tolls reached the maximum most weekdays this spring they did not remain at that price for long The following chart shows how many minutes on average the lanes were at the $10 maximum
Southbound commutes on Tuesdays saw the longest $10 maximum remaining at that price for an average of 125 minutes However Friday commutes heading south saw a $10 toll for only 30 minutes
The northbound peaks were more consistent with the lanes displaying the maximum between 65 and 110 minutes on average

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Washington State Department of Transportation
Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed General Purpose Lane Travel Time Data After 45 months of I-405 express toll lanes operation several sections of the general purpose lanes have experienced improved speed and reliability compared to before tolling
The largest improvements in travel times occur on northbound I-405 during the evening peak period between Bothell and Lynnwood Travel times in this section degraded until April 2017 when the peak-use shoulder lane opened which significantly improved travel times and reliability
Projects that have added capacity in the that section such as the toll-funded peak use shoulder lane have improved speeds in the general purpose and express toll lanes This additional general purpose capacity frees up room for vehicles allowing for faster speeds and shorter travel times However as vehicle volumes continue to increase the peak-use shoulder will only serve as an interim improvement General purpose lane speeds in the that section have been steadily decreasing from an average 46 mph in summer 2017 after the shoulder lane opened to 41 mph in spring 2019
Speeds in the southbound general purpose lanes from Lynnwood to Bothell continue to fluctuate during the morning peak period and have not seen consistent improvements When the express toll lanes first opened in fall 2015 drivers were averaging speeds of 28 mph But by late 2017 those speeds decreased to the 21-23 mph average the lanes experienced prior to tolling Since then the average speeds have continued to range between 21 and 27 mph
The southbound dual lane section between Bothell and Bellevue shows faster more reliable speeds during the morning peak period when compared to pretolling However general purpose travel times and reliability in the afternoon peak period have progressively declined in recent months due to a higher traffic demand in the area between Bellevue and NE 116th St

bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

Detailed Volume Data bull The following pages contain a summary of the requested volume data Due to the large quantity and detail of volume data requested for each travel segment the rest of this data will be provided on WSDOTrsquos website at wwwwsdotwagovTolling405libraryhtm
bull The appendix volume data summarizes volume totals by peak hour peak period daily total direction lane and by month from October 2014 through June 2019 at four screen line locations along the corridor During the first 45 months of express toll lane operations all four locations saw average volume growth compared to the year prior to express toll lane operations The rate of growth was higher during the peak periods in the peak direction than the daily volume rate of growth The rate of growth was also higher at the locations between Bellevue and Bothell than between Bothell and Lynnwood The locations between Bellevue and Bothell clearly showed greater growth during the first year of operations than the second year However the locations between Bothell and Lynnwood displayed a mix of trends over the two years Most notably the southbound AM peak period primarily grew in the first year of operations while northbound PM peak period primarily grew in the second year of operations The evening peak period data collected after April 2017 includes the operation of the peak-use shoulder lane

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling

Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate

Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas

APPENDIX C EXPRESS TOLL LANE GUIDE Operational Parameters The following parameters define how the express toll lanes operate and are critical to understanding the data and analysis discussed in this report
bull The I-405 express toll lane corridor is made up of single- and dual-lane sections The 79 mile portion of the system with two lanes in each direction between Bellevue and Bothell is referred to as the dual-lane section The 715 mile portion of the system with one express toll lane in each direction between Bothell and I-5 in Lynnwood is referred to as the single-lane section
bull The I-405 express toll lanes operate as a tolled facility on weekdays between 5 am and 7 pm except on major holidays During all other days and times the lanes are open to all traffic
bull Carpools with enough occupants may use the express toll lanes for free with a Flex Pass set to HOV mode The carpool occupancy requirement set by the Transportation Commission allows vehicles with three or more occupants to travel toll-free during peak periods on weekdays and vehicles with two or more occupants to travel toll-free on weekdays from 9 am to 3 pm
bull Peak time peak directions are southbound morning peak period (5 am-9 am) and northbound afternoon peak period (3 pm-7 pm)
bull Trip categories The following categories define toll trips Toll-exempt Buses vanpools on-duty emergency vehicles on-duty incident response and maintenance vehicles authorized in-service tow trucks carpools traveling toll-free with a Flex Pass set to HOV mode and motorcycles with a motorcycle pass
Good To Go pass Non-carpools that pay a toll using any Good To Go pass installed in their vehicle this method is the most inexpensive way to pay a toll
Photo toll Vehicles who pay the toll through a photo of the vehicle license plate There are two types of photo tolling
Pay By Plate License plates registered to a Good To Go account drivers are charged an additional 25 cent fee per trip
Pay By Mail Drivers without a Good To Go account receive toll bills through the mail for an additional $2 per trip
How Express Toll Lanes Work The I-405 express toll lanes were designed to provide faster more predictable trips for transit vanpools carpools and toll-paying vehicles While some factors such as collisions can inhibit the efficiency of the lanes managing the flow of traffic in and out of the lanes allows the lanes to maintain faster speeds than general purpose lanes during periods of congestion
WSDOT uses different strategies in the express toll lanes to promote steady speeds and more efficient person throughput including lane design vehicle limitations and tolling
57
Washington State Department of Transportation
Design Vehicles and transit can only enter and exit the express toll lanes by using specific access points Limiting merging points and managing traffic flow through dynamic tolling allows the express toll lanes to maintain more consistent speeds Drivers do not have to adjust the speeds of their vehicles as often in the express toll lanes to compensate for merging with other vehicles Some access points have a dashed white line for vehicles to merge in or out Temporary weave lanes allow vehicles to merge in and out of the express toll lanes with less disruption allowing the express toll lanes to operate more efficiently Additionally there are two direct access ramps that transit high occupancy vehicles (HOV) and toll-paying drivers can use from NE 6th Street in Bellevue and NE 128th Street in Kirkland to enter the express toll lanes directly
Vehicle Limitations WSDOT manages the types of vehicles that can and cannot use the express toll lanes during operational hours Between 7 pm and 5 am and on weekends and holidays the lanes are open to all vehicles
Express toll lanes are always free to transit vanpools and carpools that meet occupancy requirements During peak hours vehicles must have at least three occupants and a Flex Pass in order to use the lanes free of charge The lanes incentivize transit and carpooling by providing faster more predictable trips without a toll
Large commercial vehicles such as trucks over 10000 pounds gross vehicle weight are never allowed in the express toll lanes This is consistent with HOV lane restrictions throughout Washington which are designed to promote more efficient person throughput
One of the primary goals of the express toll lanes is to improve transit reliability and travel times The previous HOV lanes often experienced gridlock which interfered with transit efficiency Limiting the number of vehicles that can use the lanes ensures more reliability for transit riders Motorcycles can always use the lanes free of cost as long as they have a Good To Go motorcycle pass
Dynamic Tolling The efficiency of the express toll lanes relies heavily on the dynamic tolling algorithm which determines toll rates for the lanes The algorithm adjusts toll rates every 5 minutes based on congestion to influence the flow of vehicles into the lanes ensuring that traffic continues to move smoothly Toll rates range from 75 cents to $10
As traffic increases the toll increases As traffic subsides the toll goes down This process is called ldquodynamic pricingrdquo Dynamic pricing works to ensure that the lanes donrsquot get overloaded with vehicles and become as congested as the general purpose lanes The tolling system monitors congestion throughout the corridor which is why toll rates can vary for different destinations or ldquotoll zonesrdquo
Typically drivers chose to use the express toll lanes most during peak periods when traffic is heavy As more vehicles enter the toll rate goes up This is why when congestion is at its worst toll rates increase to the maximum rate
58
Washington State Department of Transportation
Transit and qualifying carpools can use the lanes for free This has the combined benefit of incentivizing carpooling or use of public transportation to avoid paying a toll When people opt to use these forms of transportation they reduce the number of cars on the road which in turn helps reduce congestion
Dynamic pricing is used successfully at other toll facilities around the country including San Diego Los Angeles Miami Denver Northern Virginia the Bay Area and Dallas
How the Signs Work The rates displayed on the roadway signs are for vehicles with transponders installed traveling to any point up to and including the listed destination Once a vehicle passes a listed destination the rate for that trip will be based on the rate for the next destination displayed on the sign when you entered Learn more about how express toll lanes work wwwyoutubecomwatchv=lhwRTz7zxrYampfeature= youtube
