Dynamic Traffic Management

1. Dynamic Traffic Management An overview by Frans Middelham

2. Dynamic Traffic Management Problems • Congestion Costs are 0.8 M€ per year • Accessibility of Main ports • Threat to: • Distribution function • Jobs and Economy • Environment • Safety

3. Stronger economy by improving accessibility Enabling traffic & transport growth Reliable and predictable door-to-door accessibility Innovation is a must Rapid elimination of maintenance backlogs Road pricing necessary Dynamic Traffic Management Policy Goals and Objectives

4. Dynamic Traffic Management Traffic Management as a Control Scheme

5. Dynamic Traffic Management Dynamic Traffic Management • Motorway Signalling • Ramp Metering • Dynamic Route Information • Information Measures • New Developments

6. Dynamic Traffic Management Motorway Signalling Systems since 1981

7. For: lane closures near incidents and road works queue tail warning and protection special lane signalling Throughput: increased with 4-5 % Safety assessment (1983): increased stability of traffic streams overall decrease of accidentswith 15-25% decrease of secondary accidentswith 40-50 % Safety assessment (1996): confirmation of earlier results Dynamic Traffic Management Motorway Signalling Systems since 1981

8. Dynamic Traffic Management Motorway Signalling Systems since 1981

9. Dynamic Traffic Management Ramp Metering since 1989

10. For: alleviate motorway congestion better merging discouraging of ‘rat running’ Several assessment studies: Increase of speed on motorways Major reduction of shockwaves Capacity increase 0-5% Substantial reduction of 'rat-runners' Less accidents presumable but not explicitly monitored Dynamic Traffic Management Ramp Metering since 1989

11. Dynamic Traffic Management Ramp Metering since 1989

12. Dynamic Traffic Management Dynamic Route Information Panels since 1990

13. Dynamic Traffic Management Dynamic Route Information Panels since 1990 • For: • on route information • major incident information and response • Several assessment studies: • In 'normal' conditions, 8-10% of drivers reacts on information • Network performance may increase with 0-5% • Drivers satisfied, more comfort, less stress • Different implementations and tests: • Queue length • Traveltime • Graphical

15. Dynamic Traffic Management Tidal Flow Lane

16. Dynamic Traffic Management Rush-hour Lane (hard shoulder)

17. Dynamic Traffic Management Plus Lane (small left lane, lower speed)

19. Dynamic Traffic Management Plus Lane (small left lane, lower speed) • Safety considerations (not quantified) • Less queues • Less shockwaves • Lower speed in rush hours • Better monitoring • Fast incident response

20. Dynamic Traffic Management Truck-, Plus-, Rush-hour and Tidal flow lanes

21. Dynamic Traffic Management Incident Management • Tow away trucks at incident sensitive locations • Good communication between: • Police • Fire brigade • Ambulance service • Rijkswaterstaat • Salvage companies • Assurance companies • Video surveillance at incident spots • 53 installed until 2005 • 99 expected (Tunnels, bridges, special lanes not included herein)

22. Dynamic Traffic Management Monitoringsince 1995

23. Dynamic Traffic Management Traffic Management Centers • 1997 Wijde Blik (Noord-Holland) • 1998 Geldrop (Zuid Nederland) • 2001 Oudenrijn (Utrecht) • 2003 Planken Wambuis (Noord Nederland) • 2005 Rhoon (Zuid-Holland) • Surveillance of bridges and tunnels • Surveillance of special lanes • Incident Management • Motorway-signalling • Dynamic Route Information • Dynamic Traffic Management

24. Dynamic Traffic Management Traffic Management Centers • 2001 Oudenrijn Utrecht • Countrywide Traffic Management for severe accidents and crossboarder management • 2001 Oudenrijn Utrecht • Countrywide Traffic Information Centre • Traffic Information over Radio • Contact with Serviceproviders(like ANWB)

25. Dynamic Traffic Management Traffic Management Measures

26. Dynamic Traffic Management New Developments and Trials Graphical displays at Testcentre Delft for road users acceptance and comprehensibility surveys

27. Dynamic Traffic Management New Developments and Trials • Roadsection Speed Control for pollution prevention and better air quality • spots vehicles at two cross sections • measures time travelled over cross section distance and calculates speed • Speeding drivers get a fine automatically

28. Dynamic Traffic Management New Developments and Trials • Intelligent Speed Adaption(Trial in Tilburg) for reducing speed in urban areas • Lane Departure Warning Assistant(Several Trucks Equipped)

29. Dynamic Traffic Management New Developments and Trials • Dynamic Lane Marking(field tests at A44 running)

33. Dynamic Traffic Management Traffic Management Architecture • Goals: • Structured vision on the future of Traffic Management • Starting point for all other parts of architecture • Preconditions: • Network wide, not limited by borders between jurisdictions • Cooperation between road authorities • Coordination and integration of measures • Stable and practical framework for design and implementation
