Abstract

The present paper is designed to give a sharper focus on the development of a traffic signal control system for a particular intersection. The study sets forth to examine the movements of vehicles, pedestrians and other types of traffic participants on their approaching, stopping and passing through a traffic-light regulated intersection. Accomplished is a critical examination and made is a road traffic model of a given intersection zone in order to help reduce traffic obstructions and congestion. Singled out, accordingly, are the respective traffic indicators along with some traffic flow dependencies and determined, subsequently, are the quantitative values of the key intersection performance indicators. Established is the criterion of optimality and refined are the algorithms to optimize the relevant length of the phases and the traffic signal cycles at the intersection area. Proposed, further, is a concrete solution for a definite traffic light control system.
