| 摘 要： | 基于信号2次控制模式的基本原理，对十字环形交叉口左转2次控制方法在交通设施布置和相位协调设计等方面进行改进，使其可用于多叉、中心环岛不规则等复杂环形交叉口的信号控制，并通过实例加以验证。其中，在环道相位之间通过绿灯间隔时间进行协调设计，可以使车辆连续通过相邻环道信号灯，减少车辆在环道上停车待行的次数，从而提高交叉口通行效率。

| Abstract: | Based on the secondary signal control mode, the left-turns secondary signal control method is applied to such roundabouts as multi-leg or anomaly-circled ones with improving the facility setting and coordination of phases. Hereinto,coordinating the loop phases by green light interval calculation could make vehicles pass neighboring loop signals uninterruptedly,which could reduce vehicles＇ waiting times and improve the transit efficiency of complex roundabouts. The example of Gulou roundabout in Nanjing is verified to illuminate all mentioned above. |
