Abstract

This study suggests an automate traffic signal system, which performs based on vehicle queues form at intersections. The presented system focuses on dynamic que length estimation, designing of traffic phases and signal coordination algorithms in a way that provide maximum opportunity for vehicles. The system was developed by considering a four leg intersection and graph theoretic concepts were adopted in designing traffic phases. Logical expressions have used for the signal coordination. This paper suggests using sensor networks arranged in an efficient geometry, as the estimator of traffic queue lengths. The proposed system results in four sets of traffic phase changes. The system optimizes the traffic flow by providing more opportunity for vehicles while eliminating unnecessary green time assigned for the traffic phases.
