摘　　要：为了提高城市道路交叉口的通行能力、运行效率和安全性,利用VISSIM微观仿真软件分析交叉口的车辆延误、停车次数、平均排队长度和最大排队长度等输出参数,对比优化前后的信号配时方案,结果表明:改造方案的车辆平均延误降低了38.98%,平均停车次数减少了65.13%,平均排队长度减少了55.53%,最大排队长度减少了76.5%.可为同类型城市道路交叉口信号配时优化设计提供有效的参考.In order to improve the traffic capacity,operation efficiency and safety of urban road intersection,vehicle delay,parking times,average queue length and maximum queue length are analyzed by VISSIM micro simulation software.Compared with the signal timing scheme before and after optimization,the results show that the average delay of vehicles in the modified scheme is reduced by 38.98%,the average number of parking times is reduced by 65.13%,the average queue length is reduced by 55.53%,and the maximum queue length is reduced by 76.5%.It can provide an effective reference for the signal timing optimization design of the same type of urban road intersections.
