EXECUTIVE SUMMARY
In this deliverable the off-line simulation testings for both sites (A10-WEST in Amsterdam and Corridor Périphérique in Paris) and a part of the algorithms for integrated design of control strategies applicable to corridor traffic networks are presented. A second portion of optimization based, fully integrated corridor control strategies will be presented in a future Deliverable 9B along with simulation investigations for the third EUROCOR site (M8 Corridor in Glasgow)
With respect to the Dutch site A10-WEST, this deliverable describes the ramp-metering simulation in the feasibility phase, in which two simulation studies were conducted. These studies encouraged to install 4 on-ramp installations and to investigate seven different control strategies. The first study was conducted with the assignment program SATURN. The general results show that ramp-metering will have a positive effect on the traffic flow on the A10-WEST: congestion will reduce and travel times will shorten. The urban network show some changes in usage, but the traffic situation will not deteriorate. The second study was conducted with the simulation program FLEXSYT and focused on two local situations near the motorway. The results show that the situation near the S102 junction is very critical.
For tuning and validation reasons, the local and coordinated ramp-metering schemes ALINEA and METALINE on A10-WEST have also been simulated and tested by use of the macroscopic simulation tool METANET.
With respect to the French site (Corridor Périphérique), it was decided to investigate the VMS control strategies impact on the Corridor traffic by using the simulation tool METACOR which has been already calibrated and validated on the same site. The heuristic approach has been applied including several scenarios at the strategic node in the Corridor where the diversion aspect took place.
The simulation results obtained, indicate that the improvement of the traffic conditions on the two components of the network (urban and motorway part) are fairly sensitive to the traffic portion diverted from the motorway to the urban part. Three optimal scenarios have been identified qualified and quantified. These opimal scenarios indicated that the portion of the diverted users does not exceed 400-500 veh/h. Otherwise the traffic conditions on the considered network is dramatically deteriorate.
