摘  要:文章研究了公交优先策略对协调干线及公交车辆通行效率的影响,建立了上下游交叉口综合延误模型。采用公交相位红灯早断、绿灯延长的策略,以上下游交叉口综合延误模型为优化目标,保障上游交叉口公交车辆通行的同时,尽量降低对下游交叉口及绿波协调干线的不利影响。对通州区运河西大街的相邻交叉口进行了调查,采用 VISSIM 进行了实例仿真。

Abstract: The paper studies the impact of bus priority strategy on the traffic efficiency of coordinated trunk lines and bus vehicles, and stablishes a comprehensive delay model of upstream and downstream intersections, adopts the strategy of red light early break and green light extension, takes comprehensive delay model of upstream and downstream intersections as the optimization objectives. The model ensures traffic efficiency of public transport vehicles and minimize the adverse impacts on downstream intersection and green-wave coordination trunk lines, investigates the adjacent intersection of yunhe west street in tongzhou district. It is validated by VISSIM simulation.

Keywords: traffic control; green-wave coordination; transit priority; red truncation; green extension; VISSIM
