摘　　要：公交优先是解决城市交通拥堵的有效手段,各大城市都在鼓励实施。公交优先体现在时间优先和空间优先,时间优先关键在于交叉口的信号优先,通过仿真得到公交信号优先控制方案评价指标,可以为交通管理者提供决策支持。本文研究利用Vissim微观交通仿真软件实现公交信号优先控制策略的仿真评价方法。通过在Vissim中设置车辆检测器、信号机,信号机中编辑灯组、相位、信号过渡,设置虚拟信号灯组,再结合Vis VAP编辑感应信号控制流程图,成功实现绿灯延长、信号早启、相位插入、相位逆转等公交主动优先信号控制方案的仿真。通过实例演绎该过程,证明了方法的有效性。Bus priority is an effective means to solve urban traffic congestion,and all major cities are encouraging implementation.Bus priority is reflected in time priority and space priority,the key to time priority is the signal priority at the intersection,the evaluation index of bus signal priority control scheme can be obtained by simulation,which can provide decision support for traffic managers.In this paper,micro traffic simulation software Vissim is used to realize the simulation evaluation method of bus signal priority control strategy.By setting up the vehicle detector and signal machine in Vissim,the light group,phase,signal transition in the signal machine,and the virtual signal light group are set,combining VisVAP edit induction signal control flow chart,a successful implementation and extension,signal early,phase inserts,phase reversal bus priority signal control scheme of the simulation.The validity of the method is proved by the example.
