Analysis of non-stop traffic at isolated signalised intersection by means of discrete event simulation

Abstract

This paper includes a simulation-based analysis of non-stop traffic at isolated signalised intersections. A Min-Max traffic control method is proposed to replace conventional traffic signals and maintain a continuous traffic flow. The method applicability is tested by means of Discrete Event Simulation (DES) using AutoMod software package. A set of quantitative Measures of Performance (MOP) is used to demonstrate the benefits of the proposed method compared to conventional traffic signals. In addition to eliminating vehicles stoppages, simulation results of the proposed method showed improvement in the overall traffic flow by reducing vehicle average travel time, average delay time, and the average number of vehicles at the intersection. The proposed method can be adapted to suit other types of traffic intersections and flow patterns and conditions.
