| 摘 要： | 为优化信号交叉口配时,减小交叉口延误和拥堵,通过改进现有的主干路协调控制相位相序优化算法,给出了基于双向绿波带宽最大化的相位相序优化模型。为验证优化模型的效果,采用VISSIM仿真软件对不同流量条件下的15组场景进行了仿真实验。仿真结果表明,交叉口延误减小了2%~29%,起停车次数降低了14%~28%,同时行驶时间缩短了1%~9%,可以有效改善城市主干路的交通运行状态。

| Abstract: | To reduce traffic delays,relieve congestion,and improve the operation of urban traffic network,a phase sequence optimization model was presented based on the idea of maximization of two-way green wave bandwidth.Under 15 difference groups of scenarios,VISSIM was used for testifying the effectiveness of the optimization model.The simulation results show that the optimized scheme reduces the intersection delay by 2% ~ 29%,the number of stops by 14% ~ 28% and travel time by 1% ~ 9%,which greatly improves the op... |
