A design simulation of traffic light intersection using SimEvents MATLAB

Abstract

Abstract The smoothness of traffic flow is one indicators of the excellent management by road managers, especially in the settings of traffic lights on road intersection. The time duration the red and green light must be set precisely according to the traffic density, so that the optimal and fairness queue length and waiting time are obtained for road users in each lane. Some problems at the intersection of the highway are the occurrence of very long queues in one lane, but quite short on the other lane. This happens because the setting is not appropriate on the traffic light time duration. In this article, we propose a model and simulation for intersection with traffic light using MATLAB SimEvents tools. The proposed model is to place an inhibitor module on each path at the intersection, where the entity does not flow for a certain duration of time. Through this simulation, it can be predicted the exact duration time of traffic lights based on the traffic density on each lane.
