The problem of traffic control at intersections during reconstruction is addressed in this paper. This includes not only the appropriate type of control but also evaluation of the effects of geometrics on traffic operations. Evaluation of the alternatives is accomplished through microscopic simulation using an efficient microcomputer-based program specifically 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. Because of the modeling used by the program, reliable results can be obtained in a short period of time. Input to the program is entered interactively and includes the number of lanes for each approach, the saturation flow rate for each lane, vehicle clearance times, and vehicle demands. In addition, when traffic signals are simulated, the phasing arrangement and signal timings are entered. Printed outputs for each lane include the number of vehicles serviced and statistics dealing with delays, stops, and queue sizes. In addition to the printed outputs, 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. Design tables and curves are developed for quick determination of the control policy and evaluation of is effectiveness.
