基于VISSIM的货运大道信号灯控制及交通状况改善研究

Study on the Distribution of Traffic Light and Development of Traffic Condition Based on the VISSIM

随着现代物流的发展,物流园区的运作模式应运而生。物流园区出入口货车流量逐年增加,而外围道路发展缓慢,由此造成货运大道的交通拥挤及堵塞状况。而规范道路交通标志,合理设置信号灯配时,可使道路通行能力以及事故发生率有所改善。文中根据现场调研所得数据及相应算法,在VISSIM仿真软件基础上,得出新的配时方案,使得物流中心货运大道信号灯配时合理化、最优化。

With the development of the logistics,the model of operation emerges. The number of vehicle in the entrance and the exit has increased in recent years. But traffic condition develops slowly,and it results the congestion of Freight Avenue. So designing the cycle of signal light and making a standard of the traffic sign can improve the traffic capacity and decline the rate of accident. In this paper,all the data are real,and this research did data analysis by VISSIM.
