多交叉口公交优先协调控制方法

摘要

In order to settle issues of benefit balance of traffic stream of public transport and social transport in road network,a coordination control method of bus signal priority is proposed by taking average delay per person as control objective,and is used to realize smooth running of social transport based on guaranteeing bus priority.This thesis takes average delay per person as control objective and dynamic constraint as remaining path space to build a coordination control model of bus signal priority on multiple intersections,which is conducted through simulation verification by integrating living examples and using VISSIM software.The results show that average delay of per-son,vehicles and bus transport is all reduced.The average travel time of bus transport and average stops of vehicles are all reduced.The overall operation efficiency of transport is promoted effectively.%为解决路网内公交车流和社会车流的利益平衡问题,提出以人均延误为控制目标的公交信号优先协调控制方法,在保障公交优先通行权的基础上实现社会车流顺畅运行.以人均延误为控制目标,以路段剩余道路空间为动态约束,构建多交叉口公交信号优先协调控制模型,并结合实例利用VISSIM软件进行仿真验证.结果表明:人均延误、车均延误、公交车辆平均延误均降低,公交车辆平均行程时间和车辆平均停车次数减少,交通整体运行效率有效提高.
