MICROCOMPUTER-BASED SIMULATION PROGRAM FOR INTERSECTION SITES DURING RECONSTRUCTION.

The problem of traffic control at intersections during reconstruction is addressed. This includes not only the appropriate type of control but also evaluation of the effects of geometrics on traffic operations. Evaluatin of the alternatives is accomplished through microscopic simulation using an efficient microcomputer-based program specificially developed for this purpose. The program, which runs on the IBM PC, is interactive, menu driven, and has extensive graphic capabilities for easy data entry and better inspection and understanding of the results. It allows for simulation of four-way intersections or T-intersections controlled either by stop signs in all directions or by traffic signals. The program is capable of showing on a graphics screen the simulation of the intersection, including traffic signal indications, queue formation and dissipation, and vehicle arrivals and departures.
