摘　　要：该文以无锡市蠡湖大道-周新路路口为例,介绍可变车道在信号交叉口的应用方法,包含可变车道检测器的布置、信号灯控制机理,以及交通安全配套设施的设置等,最后通过饱和度指标评价可变车道方案的实施效果。结果显示,实施可变车道能够合理分配道路资源、缓解路口通行压力、减小车辆排队长度,对于潮汐车流明显的城市,具有推广的意义。This paper introduces the application method of variable guide lanes at a signalized intersection by the example of intersection of Zhouxin Avenue – Zhouxin Road in Wuxi,including the layout of variable lane detectors,signal control mechanism and the setup of traffic safety supporting facilities,and finally evaluates the implementing effect of the variable lane scheme by the saturation index.The results show that the application of variable lanes can allocate road resources reasonably,ease the traffic pressure at intersection and reduce the length of the vehicle queue.It has a promotional significance to popularize this method particularly for a city with obvious tidal traffic.
