摘　　要：设计了8种不同控制思路下的决策方案,并在每种决策方案下,综合考虑社会车流绿波带和公交车流绿波带,分析上游交叉口到达下游交叉口的时刻对绿波带的影响情况,建立了基于绿波带宽度的优化目标.以社会车流和公交车流能够获得的绿波带宽度之和最优为原则,确定出8种决策中的最佳决策,并对控制算法进行了验证.提出的信号配时优化方法不仅可以同时满足社会车流和公交车流需求,还可以实现绿波带最大化.This paper firstly designed 8decision making plans under different control idea.Comprehensively according to band of general traffic and bus in every plan,it analyzed the time of flow from upstream arriving to downstream make influence on band to establish the optimization goal based on band.Then best plan is decided by making the sum of general traffic and bus band biggest,and the paper makes validation on this control algorithm.The Active Coordinated Control timing Optimization algorithm not only satisfy the needs of general traffic and bus,and make band biggest,which propose the urban traffic control system to direction of time allocation between general traffic and bus,and build the theoretic base on transit signal priority.
