The problem of traffic light optimization has been studied in the past twenty years. Since too many factors in the real traffic could be involved, lots of researchers proposed different kinds of models with various assumptions. In this paper, the authors propose a PSO algorithm based model to investigate how to set the given traffic lights such as that the total waiting time of roads is minimized. They demonstrate that PSO algorithm provides an optimal solution to traffic signal timing, leading therefore to improve the total flow and minimize the waiting times behind crossing points.
