摘　　要：信号交叉口延误严重影响了公交系统的运输效率以及服务可靠性。公交优先控制是降低公交车辆在信号控制交叉口延误的有效方法,然而当前研究主要考虑公交车辆的通行效率需求,欠缺考虑公交车辆之间的串车以及交叉口下游站点由于泊位数不足而导致的排队延误问题。基于车路协同环境提出了一种公交车队运行速度调控方法,让公交车辆以协同车队的方式主动适应信号配时相位;同时,对协同车队引入准入规则,使得协同车队同时满足串车预防与下游站点停靠泊位数约束的双重要求。实例研究结果表明:该方法在显著降低信号控制交叉口公交车辆停车延误的同时,可以有效避免同一线路公交车辆的串车现象以及站点排队进站情况,实现了公交运行效率与可靠性的双重提升。Signal intersection delays seriously affect the transportation efficiency and service reliability of the bus system.Bus priority control is an effective method to reduce the delay of buses at signal-controlled intersections.However,the efficiency of buses is mainly considered in current researches,rather than the bus bunching and queuing delay at downstream stations of intersections.A bus fleet speed control method was proposed based on the cooperative vehicle and infrastructure system(CVIS)environment,which makes the buses actively adapt to the signal phase in a cooperative fleet way.Furthermore,two access rules were introduced to the cooperative fleet,so that the cooperative fleet can meet the requirements of bus bunching prevention as well as the number of berths at downstream stations.The result of the case study shows that the proposed method can significantly reduce the delay of buses at signal-controlled intersections.And the phenomena of same route bus bunching and the queuing into stations are effectively avoided as well,which literally promoting the efficiency and reliability of urban bus operation.
