  1. PLANNING OF TRAFFIC MANAGEMENT SYSTEMS DURING WIDENING OF THE RING ROAD AROUND COPENHAGEN Charlotte Vithen Coordinator of Traffic Management Danish Road Directorate

  2. ROAD WORKS IN GREATER COPENHAGEN Køge Bugt north: 2002 - 2003 Motorring 3: 2005 - 2008 Køge Bugt south: 2005 - 2008 Traffic Management on Motorring 3

  3. TRAFFIC MANAGEMENT ON MOTORRING 3 • The Danish Road Directorate's largest ITS investment in one project so far • In the summer 2003 a resolution on the construction work was adopted by the Danish parliament. • The resolution holds a budget of DKK 1.790 mio. kr. (approx. 240 mio. Euro), including about 10% set aside for traffic management during construction Traffic Management on Motorring 3

  4. HOW TO SUCCEED • How did we manage to get the stakeholders to realize the needs for advanced traffic management on such a large scale? • A combination of logical and structured thoroughly analysis, experiences from the use of traffic management at previous road constructions and documentation of effects Traffic Management on Motorring 3

  5. STRUCTURE OF PRESENTATION • Decision process • Proposal for solutions • Status for the project Traffic Management on Motorring 3

  6. VVM Investigation of the traffic, environmental and economical effects of a road enlargement An essential part of the investigation is the planning of traffic management during road construction Traffic Management on Motorring 3

  7. Gathering of necessary information Analysis of traffic problems Needs analysis Assessment of ITS: Traffic control Traffic information Proposal for solutions DECISION PROCESSFOR ITS Traffic Management on Motorring 3

  8. GATHERING OF NECESSARY INFORMATION • Success criteria • Existing conditions • Planned execution of the road construction Traffic Management on Motorring 3

  9. SUCCESS CRITERIA • The number of accidents must not increase in the construction period • The road users should be of the opinion that the Roads Directorate makes a good effort to maintain the traffic flow on an acceptable level • The road users shall receive a good and effective traffic information regarding alternative routes and traffic modes • At least 80% should be content with the traffic information given Traffic Management on Motorring 3

  10. EXISTING CONDITIONS • 24 entry ramps on 17 km, some with heavy exchange of traffic • 40 bridges (crossing roads, paths, railways, streams) • AADT between 50.000 – 82.000 • Capacity fully utilized in the peek hour Traffic Management on Motorring 3

  11. Average number of minutes on a weekday in year 2000, with speed below 40 km/h Traffic Management on Motorring 3

  12. EXECUTION OF THE ROAD CONSTRUCTION • Road construction will be in progress along the whole stretch in 4 years • The traffic will be handled in 2 narrow lanes in each direction – no hard shoulder • Safety fences will create “tunneleffect” Traffic Management on Motorring 3

  13. Bridges to be replaced, rebuild or widened Traffic Management on Motorring 3

  14. Gathering of necessary information Analysis of traffic problems Needs analysis Assessment of ITS: Traffic control Traffic information Proposal for solutions DECISION PROCESSFOR ITS Traffic Management on Motorring 3

  15. ANALYSIS OF TRAFFIC PROBLEMS • Acceleration and deceleration lanes • Traffic flow • Transferred traffic to other roads • Incidents Traffic Management on Motorring 3

  16. ACCELERATION AND DECELERATION LANES • Limited length of acceleration and deceleration lanes have an unfavourable influence on traffic flow • Distance between lanes is 1 – 1,5 km • Advantageous to limit the number of open lanes Traffic Management on Motorring 3

  17. TRANSFERRED TRAFFIC • The OTM traffic model was used to determine the consequences of reduced capacity and speed on Motorring 3 • 30% of the road users will use other routes – primarily parallel routes (ring roads) • Appr. 60% of the road users on Motorring 3 are “local”. • Appr. 25% passes through the hole stretch Traffic Management on Motorring 3

  18. Primary alternative routes: ring road (02), 03 and 04 + Tårnvej-connection Traffic Management on Motorring 3

  19. INCIDENTS • Incidents in the peek hours will have a heavy influence on the traffic flow • Today there is one daily incident on the stretch - from this 1 accident a week • The number of incidents are expected to increase due to reduced traffic flow and congestion • The bridge and ramp construction works will complicate the driving conditions Traffic Management on Motorring 3

  20. Gathering of necessary information Analysis of traffic problems Needs analysis Assessment of ITS: Traffic control Traffic information Proposal for solutions DECISION PROCESSFOR ITS Traffic Management on Motorring 3

  21. NEEDS ANALYSIS • Needs for ITS contra traditional traffic management, i.e.: • Flexible solutions • Dynamic information and control • Real-time data and information Traffic Management on Motorring 3

  22. Gathering of necessary information Analysis of traffic problems Needs analysis Assessment of ITS: Traffic control Traffic information Proposal for solutions DECISION PROCESSFOR ITS Traffic Management on Motorring 3

  23. ASSESSMENT OF THE ITS SOLUTION • Needed functionality • Experience from other applications • Evaluation of technical performance and drivers behaviour and opinions • Other outside circumstances Traffic Management on Motorring 3

  24. Gathering of necessary information Analysis of traffic problems Needs analysis Assessment of ITS: Traffic control Traffic information Proposal for solutions DECISION PROCESSFOR ITS Traffic Management on Motorring 3

  25. PROPOSAL FOR SOLUTIONS • Functional description and expected effects • Priority of solutions in relation to success criteria and traffic problems • Budget Traffic Management on Motorring 3

  26. PROPOSAL FOR MOTORRING 3 • Extensive use of ITS systems • Traffic control to increase traffic safety and achieve a more fluent traffic flow • Traffic information to offer a good service to the road users and to distribute the traffic optimally in the available network Traffic Management on Motorring 3

  27. TRAFFIC CONTROL • Dynamic speed control on the whole of M3 • Queue warning • Ramp metering • Incident management Traffic Management on Motorring 3

  28. DYNAMIC SPEED CONTROL Traffic Management on Motorring 3

  29. RAMP METERING Traffic Management on Motorring 3

  30. INCIDENT MANAGEMENT Traffic Management on Motorring 3

  31. TRAFFIC INFORMATION Information pre- trip and on-trip: • VMS on M3 and radial roads: delays / travel time and special guidance • Traffic status on M3 and 04 (+ alternative routes): dynamic maps with real time and prognosis, reports in the radio, telephone-service, RDS-TMC • Information regarding alternative routes: Traffic-SMS, E-mail service • Campaigns: to influence travel time, transport mode and to change road users behaviour Traffic Management on Motorring 3

  32. DELAYS / TRAVEL TIME Traffic Management on Motorring 3

  33. TRAFFIC STATUS Traffic Management on Motorring 3

  34. ALTERNATIVE ROUTES Traffic Management on Motorring 3

  35. WHATS NEXT? • Medio February 2004: Tender • Medio April 2004: Contract • Ultimo November 2004: Testing operation • Primo December 2004: Service trial • Primo April 2005: Real operation! Traffic Management on Motorring 3
