摘要
通过在环形交叉口进口道和环道上设置信号灯,控制左转车辆两次停车通过交叉口的信号控制方法,是对负荷较大的让行控制大型环形交叉口较好的改善措施。运用微观仿真软件VISSIM仿真一定流量条件下设置左转两步信号控制环形交叉口和让行控制环形交叉口的运行状况,并进行比较分析,得出两种控制方式各自的优缺点和流量适用范围。
Setting signal on each in-lane and circle-lane of a large roundabout to control left-turn vehicles stop twice is an effective method to improve some large roundabouts＇ performance,which is called two-steps left-turn signal control.This paper simulations and analyzes the operation status of two-steps left-turn and yield signal controls of roundabout under a certain traffic flow by using the traffic simulation software VISSIM,and with comparison,advantages, disadvantages and applicable range of two control modes are analyzed.
