摘要
如何缓解交通拥堵问题是近年来的一个热点话题,国内外一直致力于对此问题进行研究,其中对于交通信号控制方法的研究较多。目前常用的城市交通信号协调控制的方法为单点控制、干线控制和区域控制,这些交通信号控制方法经历了从手动到自动、固定周期到可变周期、无感应控制到感应控制、单一交叉口到关联交叉口再到区域交叉口控制的进步历程,每种方法相应可以满足不同交通系统的控制需要。基于国内外现有的研究成果,对单点控制、干线协调控制和区域协调控制方法进行了梳理,为发展智能交通,解决交通拥堵问题提供更有效的途径。
How to alleviate traffic congestion is a hot topic at home and abroad in recent years.And people pay more attention to traffic signal control methods.Now,the common methods of coordinated control of urban traffic signals are single-point control,trunk coordinated control and regional coordinated control.All in all,these traffic signal control methods have experienced the progress from manual to automatic,fixed to variable,non-inductive control to inductive control,single intersection to associated intersection and regional intersection control.Each method can meet different traffic system control needs accordingly.Based on the existing research results at home and abroad,the single-point control,trunk coordinated control and regional coordinated control methods are introduced and sorted out,and it can provide more effective means to develop the intelligent transportation and solve traffic congestion.
