摘要
在对平面交叉口交通特性进行分析的基础上,提出相应的交通组织优化措施.结合案例云南省曲靖市翠峰东路与书院路交叉口的调研数据,针对该路口现状存在的诸多问题,分别从渠化设计、信号控制和交通管理等方面提出优化改善方案,并通过微观仿真VISSIM软件对改善前后的交通运行效率指标进行对比分析.仿真结果表明对交叉口进行合理的交通组织优化设计,可一定程度上降低交叉口的平均延误、排队长度和平均停车次数,提高服务水平和通行能力.
The traffic characteristics of the road intersection are analyzed firstly,and then the corresponding measures of traffic organization optimization are put forward.Combined with the investigation data of the intersection of Cuifeng East Road and Shuyuan Road in Qujing City,Yunnan Province,this paper puts forward the optimization and improvement schemes in view of the current situation of this intersection from many aspects,such as channelization design,traffic signal control,traffic management.The traffic efficiency indexes before and after improvement are compared and analyzed through micro-simulation software VISSIM.The simulation results show that the reasonable design of traffic organization optimization for the intersection can reduce the average delay,queue length and average stops of the intersection to a certain extent,and improve the service level and road capacity.
