Abstract

A pedestrian-actuated traffic signal control system has been implemented at intersections where most traffic conflicts are between vehicle flows and pedestrians. When properly implemented, such a system can process traffic flows more efficiently than a pretimed control system. It is not yet clear, however, how a pedestrian-actuated system can be best utilized, and misuse is not uncommon. This study provides a basis for proper use of a pedestrian- actuated system by characterizing the performance of the system at isolated intersections in terms of traffic delay. Three optimization problems of signal setting--the minimization of (a) average vehicle delay, (b) total delay of pedestrians and vehicle riders, and (c) the difference between average pedestrian delay and average vehicle delay--are discussed.
