9th March 2010
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
