APPLICATION OF NETWORK SIMULATION MODELS TO THE ANALYSIS OF URBAN INTERSECTION PERFORMANCE

It was the objective of the study to adapt and validate the UTCS-1 Network Simulation Model for use in the analysis of traffic performance of single urban intersections. Modifications to UTCS-1 in order for it to be applicable to a single intersection are described. The modified model was tested and compared to two other single intersection simulation models. The model was then validated by simulating isolated intersections in Oakland, California and Arlington, Virginia. As a demonstration of the model, two examples of applications were made. In the first example, the effectiveness of allowing right turns against a red signal indication was examined. In the second, a sampling procedure for estimating stopped delay at intersections was analyzed. It is concluded that UTCS-1S is an accurate and flexible model suitable for use in the analysis of the performance of individual intersections.
