Single point diversion of freeway traffic. Paper prepared for the 55th Annual Meeting of the Transportation Research Board TRB, Washington, D.C., January 1976.

This paper discussed 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 those periods when the traffic demands exceed some roadway capacities. The evaluation of these policies has shown a consistent reduction in roadway congestion with a corresponding reduction in motorist delay and improvement of the overall system operation. The principal tool used for system evaluation was the Sperry Traffic Analysis and Research (STAR) simulation program. This macroscopic freeway simulation is based on the hydrodynamic traffic flow model.
