摘　　要：城市交通量不断增加,一些交叉口进口道设计为“主路+隔离带+辅路”,且辅道中再设有左直右车道,如何对该交叉口进行科学配时成为实际难题。文中以旅行时间分布法计算出的车均延误作为评价指标,比较辅道独立法、辅道折算系数法以及遗传系数法,选出最佳配时方法与信号方案。然后以常德市武陵大道与洞庭大道交叉口为例,分别使用HCM延误、Vissim仿真以及旅行时间分布法延误分析现用方案与上述三种方案的优劣,验证了辅道独立法更为简单实用。The traffic volume of the city is increasing,and some intersections are designed as main road、isolation zone and auxiliary road,and the auxiliary road equipped with left、straight and right lane,so how to make scientific timing scheme of the intersection becomes a practical problem.Travel time distribution method was used to calculate the vehicle delay,which is regarded as the evaluation index,compared with the alone auxiliary method,the auxiliary conversion coefficient method and the genetic algorithm method,and the best timing method and signal scheme are slected.This paper,takes the intersection of Wuling Avenue and Dongting Avenue in Changde City as an example,HCM delay,Vissim simulation and travel time distribution method are used to analyze the current scheme,and above mentioned three methods and the feasibility of the alone auxiliary method is proved to be more simple and practical.
