| 摘 要： | 城市无环岛5路交叉口交通拥挤和交通事故频发，提高该类交叉口的安全性及其通行效率是城市交通规划设计研究的重要组成部分。交通学院以武汉市南湖壕沟无环岛5路交叉口为例，采用交叉口复杂度、车辆平均延误、排队长度、停车次数及服务水平作为评价指标，对交叉口渠化、交通组织、信号配时等方面进行组合优化设计研究，结合微观交通仿真软件Vissim进行模拟评价，仿真结果表明优化设计明显改善了该路口交通运行状况。

| Abstract: | Traffic congestion and traffic accidents frequently happen in urban five-road intersections without roundabout.It is important to improve the safety and efficiency of such intersections in the urban transportation planning/design context.Taking the Nanhu-Haogou five-road intersection in Wuhan as an example,this paper uses the following as the evaluation indices: intersection complexity,vehicle average delay,average queue length,stopping times and level of service and study an optimization design in channeli... |
