为克服干线绿波协调控制中上游交叉口公交优先控制策略对绿波协调方案和下游交叉口造成的影响，在单点公交优先控制策略的基础上提出了一种综合考虑上下游交叉口延误的干线公交优先模型。该模型以红灯早断、绿灯延长为基本策略，将相邻上下游交叉口车辆综合加权延误作为优化目标，保证上游交叉口公交优先通行的同时，尽量减少对干线绿波协调控制和下游交叉口的影响，并以干线协调控制下的上下游交叉口为例，利用 Vissim 进行仿真验证。结果表明：该模型与单点公交优先相比虽然上游交叉口车均延误增加2.6%，但下游交叉口车均延误降低10%，上下游交叉口综合车均延误降低3.7%，一定程度上缓解了公交优先控制策略与绿波协调控制策略互相冲突的问题。

The coordination of green-wave and the efficiency of downstream intersections are affected by the transit signal priority (TSP)set up at the upstream intersections.In order to address this issue,a TSP model that considers the delays at the upstream and downstream intersections along arterial roads is presented in this paper.The extension of green light phase and the reduction of red light phase are used in the model.The weighted delays of upstream and downstream intersections are used as the performance index.This model ensures the transit priority and reduces its impacts on green-wave coordination.It is validated by Vissim simulation in this study.The results show that the average vehicle delay at down-stream intersections decreases by 10%,although the average vehicle delay at upstream intersections increases by 2.6%.The weighted delay of upstream and downstream intersections decreases by 3.7% comparing with the isolated TSP control strategy.The study results clearly show that the strategy in the proposed model can reduce the conflict between the TSP and the green-wave coordination.
