The adaptive algorithm of a four way intersection regulated by traffic lights with four phases within a cycle

Abstract

In many urban areas, road traffic is mostly regulated by traffic lights, which – if not configured effectively – can lead to unnecessary long waiting periods when crossing the intersection and increasing the overall congestion delay. Inefficient configuration of traffic lights is still present, particularly in traffic zones where the functioning of most traffic lights is based on a fixed mode of operation. In order to improve the functioning of traffic lights and reduce the overall congestion delay, the aim of this paper is to suggest a software solution for traffic light system operation that enables an adaptive mode of operation on Four Way Crossing Regulated by Traffic Light-Four phases. In such a mode of operation, the cycle duration, green light, and the duration of the phases can be adjusted to the traffic conditions at the intersection.
