Dynamic Traffic Management An overview by Frans Middelham

June 13th, 2006 Dynamic Traffic Management2 Problems Congestion Costs are 0.8 M€ per year Accessibility of Main ports Threat to: –Distribution function –Jobs and Economy –Environment –Safety

June 13th, 2006 Dynamic Traffic Management3 Policy Goals and Objectives 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

June 13th, 2006 Dynamic Traffic Management6 Motorway Signalling Systems since 1981

June 13th, 2006 Dynamic Traffic Management7 Motorway Signalling Systems since 1981 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 accidents with 15-25% –decrease of secondary accidents with % Safety assessment (1996): –confirmation of earlier results

June 13th, 2006 Dynamic Traffic Management9 Ramp Metering since 1989

June 13th, 2006 Dynamic Traffic Management10 Ramp Metering since 1989 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

June 13th, 2006 Dynamic Traffic Management11 Ramp Metering since 1989 Until Total44 Planned16

June 13th, 2006 Dynamic Traffic Management12 Dynamic Route Information Panels since 1990

June 13th, 2006 Dynamic Traffic Management13 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
