A distributed phase time optimization method of the coordinated control for active bus signal priority

Active bus signal priority controlling method at a single intersection bases on single bus flow priority, applying for coordinated control in many intersections. This paper comprehensively considered green wave of general traffic and bus traffic in every decision project, made the priority signal distributed phase time parameter, based on green wave band width of general traffic flow, general flow delay and bus flow delay, made a comprehensive benefit preferred model, made the best decision, verified the controlling algorithm.
