A STUDY ON THE TRAFFIC FLOW OF THE MAIN ROAD UNDER THE TRAFFIC LIGHT CONTROL

Open publisher page 3 citations

Abstract

This paper presents a cellular automata model that simulates the traffic flows on a main road in the city network in which there are traffic lights at the intersections. Factors relating to the formation and spread of traffic shock waves are investigated. It was found that the traffic flows have several peak values. When distances between the intersections are equal, for a fixed value of cycle times of the traffic lights, the current does not depend on the density of vehicles for a range of density. For a high density, when the distance between the intersections is greater than a certain value, the traffic flow remains constant.
