交叉口定时信号配时优化设计方法

分析了现行交叉口定时信号配时设计流程中存在的不足,提出了将空间设计和时间设计结合起来的新的信号配时优化设计流程,建立了三目标配时优化模型,并以此模型为基础进行了实例分析,证明该模型优于F.Webster模型,对我国城市信号交叉口的信号配时有一定的指导作用。

Optimization Design method on Signal Timing of Intersections

This paper summarizes the current signal timing design flow of intersections.Through the amelioration,the paper proposes a new design method which combines space and time together,and founds TTTOM(the Three-Targets Timing Optimization Model).By analysis based on this model,it can see that this model precedes the F.Webster model,and there are some guidances to the signal timing design flow of intersections in our country.
