摘　　要：为解决公交车辆与社会车辆绿波协同问题,提出一种公交优先绿波协同交通控制方法。该方法以人均延误最小及公交车辆不停车通过交叉口为目标,以车速、站台停靠时间和信号优先时间为约束条件,构建协同平衡模型。根据公交车辆实时动态需求,平衡干线的绿波时间与公交车辆的运行时间,对需要在交叉口停车的公交车辆实行速度引导与站点停靠时间及信号优先控制。以桂林市中山路干线为例,利用Vissim仿真系统建立场景。结果表明,应用该方法后的车辆平均排队长度和人均延误均有所降低,验证在满足社会车辆绿波下同时满足公交车辆绿波的良好效果。In order to solve the problem that bus can't cooperate with the green wave of private vehicles,a new bus priority green wave cooperative traffic control method is proposed.The coordinated balance model is constructed with the goal of the minimizing per capita delay and the non-stop crossing of bus at intersections,and with the constraints of bus speed,platform dwell time and signal priority time.According to the real-time dynamic demand of bus,the green wave time of the arterial and the bus travel time are balanced,speed guidance,dwell time control and signal priority control are implemented for the bus that need to stop at the intersection.Taking the Zhongshan Road in Guilin as an example,the simulation scene is established by Vissim.The simulation results show a reduction in both average queue length and per capita delay for this study.This paper can satisfy the green wave of private vehicles and bus at the same time.
