Freeway Volume-Crash Summary

Twin Cities Metropolitan Area_____________________________________________________________________Purpose and NeedThe purpose of this report is to identify segments on the metro area freeway system that experiencehigh numbers of crashes. This information is then used for:

• identification of locations that experience higher crash rates due to recurringcongestion.

• project planning• resource allocation (Traffic Management Systems, FIRST routes, incident

management, etc.)

This report is typically published on an annual basis. Data within this report represents 2002 peakperiods and 24-hour volume levels, crashes, and crash rates for each freeway segment.

_____________________________________________________________________

IntroductionThis report is a summary of the metro area freeway system’s crash data and volume data in 2002. The report has been developed by the Traffic Management Center since 1975 and was primarilyused by TMC personnel to help establish priorities for future traffic management systems. This yearthe report has been reformatted to help broaden the audience of the report. Graphicalrepresentations of the data where added to make the report more user friendly and to show theconnection between congestion and freeway crashes.

Congestion and Freeway CrashesFreeway congestion and freeway crashes are related. Freeway congestion can be defined as eitherrecurring congestion or incident related congestion. Recurring congestion is congestion that occursat the same location on a daily basis due to some type of roadway characteristic that affects trafficflow such as a major interchange, lane drop, or weaving traffic. Incident related congestion can becaused by a crash, a stalled vehicle, debris on the roadway, adverse weather, or a special event. According to the FHWA, incident congestion accounts for up to 50% of the total congestion.

2

Increased congestion increases the potential forcrashes to occur on the freeway. In 2002, there were9,439 crashes on metro area freeways. As the chartentitled “Crashes by Peak Period” shows, 47% of thecrashes occurred during the peak travelhours. The peak hours consist of 6:00 am to 8:59am during the AM Peak and 3:00 pm to 6:59 pm during the PM Peak, Monday through Friday. Weekends and non-peak weekday hours make up theOff Peak crashes. While peak hours consist of onlyseven hours a day or 20% of hours in a week, Mondaythrough Friday, they represent almost half the numberof freeway crashes.

Freeway crashes are attributed to shock wave activity, merging traffic, and weaving traffic oncongested roadways. These types of crashes are typically side-swipe or rear-end type collisions. The potential for more severe crashes typically occurs where free flow traffic and congested trafficconverge. Examples include when free flow traffic meets slower moving congested traffic around ahorizontal or vertical curve where the congested traffic may be unexpected. Another situation iswhere one or two lanes of traffic are congested due to a high volume entrance or exit ramp andadjacent lanes are free flowing traffic.

Incident-related congestion is unexpectedsince it can occur during peak or non-peak hoursand in areas where motorists may not expect slowmoving traffic. A study done by the TrafficManagement Center in 1982 found that 13% oftraffic crashes were secondary crashes fromincident-related congestion. An example of howincident congestion can cause secondarycrashes occurred on February 1, 2002. One crash on I-35W during the mid-day hourscaused congestion on I-35W and Highway 62 overa two hour period, which led to six additional crashes. Most of these crashes occurred at the boundarywhere free flow traffic meets congested traffic.

Study MethodologyThe freeways studied in this report are shown in the map on page 5. Each interstate and trunkhighway is divided into sections with breaks based on changes in traffic volumes and other freewaycharacteristics.

The study uses crash data from the Department of Public Safety's crash record database. Mn/DOT’sOffice of Transportation Data and Analysis processes the data with a crash analysis routine appliedto the Transportation Information System (TIS). Crash data include only vehicular crashes on themainline; interchange-related data is not included.

Traffic volume data was obtained from the RTMC and the Office of Transportation Data Analysis.Each freeway link between entrance and/or exit ramps was assigned an annual average daily trafficvolume (AADT). For even years (1998, 2000, and 2002), the AADT is based on actual trafficcounts. For odd years (1999 and 2001) AADT is based on actual counts recorded from the previouseven year and projected to the next year’s levels. Averages of link volumes, weighted for linkdistances, on each part of a freeway section were used to determine the average volume for eachfreeway section.

Individuals using data from this report should be aware that weather, construction, and maintenanceactivities were not analyzed with respect to crash rates shown.

Crash rates are expressed in units of crashes per million vehicle miles traveled (Crash/MVM) andcalculated as follows:

Annual Rate = Total Annual Crashes x 1,000,000Section Length (Miles) x AADT x 365

Peak Period Rate = Total Annual Peak Period Crashes x 1,000,000Section Length (Miles) x Average Period Volume x 260

Peak periods for this study are from 6:00-8:59 A.M. and 3:00-6:59 P.M. weekdays.

Segment Definition

For purposes of this report, freeway segments are generally defined from the lowest logpoint listingnumber to the highest logpoint listing number of a particular section of roadway. The limits of thefirst study segment for each corridor includes two interchanges. The next segment of that roadwaystarts just past the previous interchange and ends just past the next interchange. Segmentdefinitions continue in this manner to the end of the reported roadway. NOTE: Only crashesoccurring on the mainline are included – no interchange ramps or overpass crash data is included inthis study.

Example:

SECTION OF I-94 CORRIDOR

Segment 1: MN 101 to I-494This is the first segment reported on this roadway in this study. The logpoints usedincludes the crashes that occurred just prior to the Hwy 101 interchange to just pastthe I-494 interchange.

Segment 2: I-494 to CR 81This segment includes crashes that occurred from just past the I-494 interchange to just past the CR 81 interchange.

Segment 3: CR 81 to I-694This segment contains crashes that occurred from just past the CR 81 interchange tojust past the I-694 interchange.

Summary of ResultsThe table below summarizes yearly crash totals and crash rates for 1996 through 2002. There were9,439 crashes in 2002, resulting in an urban freeway crash rate of 0.96 Crashes/MVM. Crashesrose slightly from the year 2001 when there were 9,395 crashes, or 0.92 crashes per million vehiclemiles in a 24 hour, 7 days per week period.

During the AM peak periods, there were 1,556 crashes in 2002, resulting in a crash rate of 1.64Crashes/MVM. During PM peak periods, there were 2,886 crashes in 2002, or 2.27 Crashes/MVM.As seen in the line graph, crash rates during the peak periods have continued to increase since1996, due mainly to increased levels of congestion.

Crash MapThe following map graphical shows the frequency of crashes on metro area freeways for both theAM Peak Period and the PM Peak Period combined. Crashes were plotted as the number ofcrashes per reference point. Since reference points on metro area freeways are approximately onemile apart, this map represents the frequency of crash as the number of crashes per mile.

Approximately half of the segments on the map were in the category of 0 to 9 crashes per mile. Theremaining 50% had greater than 10 crashes per mile with 5% of the segments having greater that 44crashes per mile. The maximum number of crashes per mile for both peaks was 137, which was onI-94 in the I-35W commons.

Comparing the following crash map with the congestion maps from the 2002 congestion report, thecorrelation between congestion and crashes can be seen. Areas experiencing heavy congestionalso show a high frequency of crashes. The congestion maps are included in the appendix of thisreport for reference.

SELECTED INTERSTATE AND STATE ROADS

How To Read This Section

The following pages provide more detailed information on selected metro area freeways. The firstpage for each metro area freeway has a bar graph that shows the trends in crash rates from 1996 to2002. Each grouping of bars in the graph represents a specific segment of that freeway. Individualbars within the grouping then represent the crash rate for a given year. The table below the barchart represents 2002 volume and crash data for that freeway.

The second page for each freeway contains two bar charts that show the number of crashes perreference point during the AM and PM peak periods. Reference points on metro area freeways areabout one mile in length. The purpose of these charts is to show locations where there are a highnumber of crashes. These locations are typically at major interchanges, bottlenecks, and areaexperiencing high levels of congestion.

• Heaviest levels of congestion on I-35E are on the segment from I-94 to MN 36during both the AM and PM peak periods. The 24-hour crash rate for this sectionis the highest segment for I-35E with a rate of 1.35 Crashes/MVM. Crash ratesduring the AM and PM peak periods are 3.28 Crashes/MVM and 3.22 Crashes/MVM.

• Referring to the “I-35E Crashes per Reference Point” chart for the PM peak period,a high number of crashes occur on I-35E from I-94 to Maryland Ave due to increasedlevels of congestion and merging traffic. Shockwave activity traveling back into thecommons of I-94 and weaving traffic contributes to crashes in this area.

• In 2002, the 24-hour crash rates increased substantially along the I-35W segmentsfrom the east junction of MN 62 to the east junction of I-94 in Hennepin County. Thenumber of crashes accounted for about one-third of the total number of crashes alongI-35W for the 24-hour period. Congestion on this segment is heavy in both directionsduring both the AM and PM peaks periods.

• The highest number of crashes per reference point for the AM peak period occurs atCliff Rd. This area is heavily congested in the morning from the Minnesota RiverBridge back to MN 13.

• The PM peak period sees the highest number of crashes per reference point betweenMN 65 and Lake St. Crashes occur here in the southbound lanes of I-35W due toshock waves, merging traffic from downtown, and weaving traffic as motorists switchlanes for the MN 62 junction downstream.

• The I-394 to West I-35W segment of I-94 had the most crashes, 355 crashes in a24 hour period. While there were 86 more crashes at this location than the 24 hourperiod in 2001, the AM peak increased more than 70% from 29 to 50 crashes.

• In 2002, the greatest number of crashes during any peak period at any referencepoint along Twin Cities metro freeways occurred at MN 65/I-35W. There were 107crashes during the PM peak period at this location. Crashes on westbound I-94 atMN 65/I-35W during the PM peak period are attributed to heavy congestion, mergingtraffic from I-35W and Hiawatha Ave., and weaving traffic as motorists switch lanesfor the I-394 junction downstream.

• The segment of I-94 that showed the greatest increase in the number of crashes wasMN 101 to West I-494 where total crashes increased from 192 in 2001 to 292 in 2002over a 24 hour period, a 50+% surge.
