基于VISSIM的逆向可变车道设计研究——以南通市世纪大道与工农南路交叉口为例

Research on Reverse Variable Lane Design Based on VISSIM: Taking the Intersection of Century Avenue and Gongnong South Road in Nantong City as an Example

本文对逆向可变车道进行深入研究,并以南通市的一个交叉口作为改造对象,通过Vissim软件进行模拟分析,验证采用逆向可变车道后,该交叉口的四个交通指标均得到了优化,如平均排队长度指标降低了30.7%,平均延误时间降低了27.6等。

This paper conducts in-depth research on reverse variable lane,takes an intersection in Nantong City as the transformation object,and conducts simulation analysis through Vissim software to verify that the four traffic indicators of the intersection have been optimized after the use of reverse variable lane,such as the average queue length index reduced by 30.7% and the average delay time decreased by 27.6.
