2Weekly Supervisor Meeting – Project Waalbrug

Outline

• Introduction• Solution Space• Alternatives

3Weekly Supervisor Meeting – Project Waalbrug

Solution Space

Result from brainstorm session:Solution ideas

• - Road pricing on the Waalbrug (in peak hours)

• - Improving the Waalsprinter service and PT

• - Separation of flows in the singles

• Bridges/tunnels

• Lowering the road level

• Dynamic Traffic Management (DTM)

• Dynamic route guidance panels

• Green waves

4Weekly Supervisor Meeting – Project Waalbrug

Solution Space (continued)

• PT alternatives not using the Waalbrug(e.g. Ferry)

• Diverting traffic flows to alternative routes, including those that include

the Stadsbrug

• Redesign the Keizer Traianusplein

• Location basic services in the northern part

• Central parking places (north)

• New parking facilities in the city centre (near Traianusplein)

• Hov lanes

• Extra bridge

• Extending/widening waalbrug

5Weekly Supervisor Meeting – Project Waalbrug

Alternatives: Rough sketches

• Route Guidance system• Improving public transport• Redesign Keizer Traianusplein• Reducing conflicts on the Singels• HOT lanes• Ferry system

6Weekly Supervisor Meeting – Project Waalbrug

Route Guidance

Goal: Better use of capacity, to distribute traffic equal over available routes

Current Situation:• One car route to city center

available (via Waalbrug).

7Weekly Supervisor Meeting – Project Waalbrug

Route Guidance

Solution directions

• To reduce the delays divert other traffic from the north to other routes, like

via the Stadsbrug or A50/A73

• Matrix signs (see previous sheet) on the routes to Nijmegen (Junction Ressen)

• Smartphone applications with traffic situation status include alternatives like

Waalsprinter

• Remark: Reliability is important, only then people are going/willing to switch.

8Weekly Supervisor Meeting – Project Waalbrug

Improving Public Transport

• Goal: Give a better alternative for car users to access the city center

• Solution directions:• Increase service - more routes, increased frequency etc.• Improved user information - real-time information etc.• Lower fares and discounts• Services targeting particular travel needs, such as express

commuter buses, etc.

9Weekly Supervisor Meeting – Project Waalbrug

High Occupancy Toll-Lane (HOT)

•Goal: Better use of capacity of the Waalbrug

•Current situation Waalbrug; Bus lane for Waalsprinter & Local Busses

•Solution Direction:Combines HOV and pricing strategies by allowing single occupancy vehicles to gain access to HOV lanes by paying a toll.

10Weekly Supervisor Meeting – Project Waalbrug

HOT- Principle

• Route pricing depending on time of day (peak hours)• Dynamic variable pricing depending on the observed

number of vehicles • The fare of the HoT lane depends on the number of

vehicles on the lane and changes every 5 minutes to maintain a minimum LOS(level of service)

• Per trip charging• Solo drivers willing to pay the charge only during peak

hours

12Weekly Supervisor Meeting – Project Waalbrug

Ferry-system

• Introduction of a speedy fast passenger Ferry to enter the city center from the north

• Keizer Trajanusplein – February 5th – 13.00h

13Weekly Supervisor Meeting – Project Waalbrug

Fast passenger ferry

• Goal: • Give an alternative to cross the Waal without using the current

alternatives

• Solution Direction: • Focus is more on people who work in the city center area, also

people who wants to visit the city center• Parking places to park your car and use the ferry to cross the Waal• No tariff (in peak hours)• ‘recreation’ while going to your work

14Weekly Supervisor Meeting – Project Waalbrug

Redesign Keizer Traianusplein

• Goal: Improving flow on Keizer Traianusplein

• Current situation: Bottleneck during peak hours, many conflicts; especially with left turns

• Solution direction: improving flow on Traianusplein by reducing conflicts through a redesign.

15Weekly Supervisor Meeting – Project Waalbrug

Redesign Keizer Traianusplein

• Facilitate left turn on viaduct• Remove conflict by lowering lanes for straight traffic

Current traffic situation

16Weekly Supervisor Meeting – Project Waalbrug

Reducing conflicts on Singels

Traffic intensities on Singels (evening peak)

• Goal: Improving flow on Singels

• Current situation: Conflicts on crossings on Singels disturb flow of traffic, major left turn on Prins Bernhardstraat

• Solution direction: reduce conflicts on Singels by changing traffic situation and diverting flows

17Weekly Supervisor Meeting – Project Waalbrug

Reducing conflicts on Singels

• Reducing conflicts on two crossings (Prins Bernhardstraat and Berg en Dalseweg)

• Diverting left turning traffic to Bijleveldsingel

• Reduces number of traffic light phases and waiting time

Concept new traffic situation on Singels
