SINGLE POINT DIVERSION OF FREEWAY TRAFFIC

This paper discusses the development and application of diversion control policies for the routing of freeway traffic at a single point. Specifically, this class of policies can be used to allocate traffic flows over a two-roadway system during periods when traffic demands exceed some roadway capacities. Evaluation of these policies reveals a consistent reduction in roadway congestion, a reduction in motorist delay, and an improvement in overall system operation. The principal tool used for system evaluation was the Sperry traffic analysis and research simulation program. This macroscopic freeway simulation is based on a hydrodynamic traffic flow model. The resulting optimized policies have been incorporated into the design for a practical real-time alternate routing system by Sperry Systems Management. /Author/
