A Phase-by-phase Traffic Control Policy at Isolated Intersection Based on Cooperative Vehicle-infrastructure System☆

The recently developed Cooperative Vehicle Infrastructure System (CVIS) enables the monitoring of high resolution vehicle probe data. In this paper, a phase-by-phase control policy was developed, which can optimize split and cycle under the concept of every vehicle on the road communicating to the controller at an isolated signalized intersection. The green time of each phase was determined at the beginning of itself subject to the corresponding approaches’ probe data. The proposed policy was compared with the pre-timed control policy by simulation experiments, and the results shown that the authors policy is better in terms of average queue length and total time spent by all the vehicles in the network (TTS).
