摘　　要：为缓解交叉口拥堵问题,提高交叉口干线之间的通行效率,提出结合车速引导的相邻交叉口公交信号优先协调控制方法.通过设置预指令车速信息引导公交车队在上下游交叉口运行期间产生集结,从而扩大社会车辆绿波带带宽,确保公交信号优先协调控制方案的有效实现.仿真试验结果表明:协调控制中上下游交叉口社会车辆与公交车辆延误与停车次数有效降低;确保公交优先通行的同时,改善交叉口干线之间车辆排队情况,提高绿灯时长的有效利用率,缓解交通拥堵.In order to alleviate the congestion problem at intersections and improve the traffic efficiency between trunk lines at intersections,a bus signal priority coordination control method combined with speed guidance at adjacent intersections was proposed.By setting the pre-command speed information,the bus fleet was guided to gather during the running of the upstream and downstream intersections,so as to expand the bandwidth of the green band of social vehicles and ensure the effective realization of the bus signal priority coordination control scheme.The simulation results show that:①The delay and parking times of social vehicles and public transport vehicles at the intersection of upstream and downstream are effectively reduced by coordinated control;②This scheme can ensure the priority of public transportation.Moreover,the queuing situation of vehicles between trunk lines of intersections is improved and the effective utilization rate of green light duration is promoted,thus enhancing overall efficiency of adjacent intersections.
