Abstract

The purpose of this study is to determine the effects of pedestrian movement on vehicle flow at signalized intersections. Specifically, a computer simulation model written in General Purpose Simulation System language was developed to calculate vehicle seconds of delay at two-lane by four-lane street intersections with fixed-time signal cycles.

Two intersections, operating under different conditions, were simulated at various pedestrian and vehicle flow volumes. Possible warrants, based on simulation output, for the inclusion of a separate pedestrian signal in the signal cycle for the two intersections studied were discussed.
