Simulation of the traffic light optimization algorithm based on the current traffic frequency

Abstract

Due to the constant increase in the number of inhabitants in cities, the number of cars inevitably increases, which contributes to the creation of ever-increasing traffic jams. These traffic jams culminate at particular times of the day on specific road routes and junctions. One of the ways to regulate traffic at intersections is the use of traffic lights, and the operation of traffic lights for different traffic intensities is generally corrected by setting various modes of operation of traffic lights in which the duration of green and red lights change. This paper examines the possibility of applying an algorithm to optimize traffic light operation in real time based on the current traffic frequency measured by inductive traffic counting loops. The algorithm was tested on a simulator developed for this need based on real intersections in a city.
