基于图解法的城市干道信号协调控制设计

针对淮安市淮海南路现行交通信号控制系统存在交通拥挤、停车次数多、运行车速慢等问题,提出交通信号协调控制方式。应用Webster法对各进口道进行重新配时,然后进行各交叉口的信号协调控制方案设定,再用图解法求得各交叉口信号相位差,最后通过vissim仿真。通过研究得到以下结论:干道信号协调控制方案在交通延误、停车次数、运行车速等指标方面比现行的信号控制方案优越。

Research on Signal Coordination Control in Urban Arteries Based on Graphic Method

Aiming at the traffic signal control problems existing in the south of Huaihai Road in Huai'an city such as large traffic jams,large number of car stops and low running speed,a method for traffic signal coordinating control was proposed.Firstly,Webster method was used to reset the time of each entranceway,and signal coordination control plan for each crossroad was made.Then graphic method was used to get the signal phase difference of each crossing,and vissim simulation was conducted.It is concluded that th...
