COSMOS (Congestion Management Strategies and Methods in Urban Sites) is one of the European ATT projects. COSMOS will develop, validate and demonstrate new procedures for reducing and, where possible, preventing congestion in densely trafficked urban areas. These procedures comprise special modules for Congestion and Incident Management (CIM) on the basis of Automatic Congestion and Incident Detection (ACID) which are to be included in SCOOT, UTOPIA and MOTION, and strategies for rerouting traffic to make the best use out of the capacity at junctions and in the links between them. COSMOS started with the definition of general and specific user requirements for congestion and incident management. In the next step, common control strategies for Congestion and Incident Management with on-line network signal control have been developed. These strategies take account of the information available from Automatic Congestion and Incident Detection or from the system operator; the possibilities of on-line urban network signal control; and the restrictions set by the demands of other UTC systems. The presentation of these strategies is the main focus of the paper.
