相邻近距桥头交叉口信控协调优化

Coordination and Optimization of Signal Control at Adjacent Bridge Intersections

为提高相邻近距桥头的通行能力,减少桥面车辆排队和排队车辆的制动等影响,以泉州市德化县龙津桥两端交叉口为例,以排队长度、路段平均行程速度等为目标评价指标,借助Synchro仿真软件进行分析评价。在单点信控优化的基础上,根据高峰时段的交通量和交通管理措施,采取“双向绿波”的信号协调控制优化策略,建立优化的信号协调控制系统。

In order to improve the traffic capacity of intersections and reduce the influence of vehicle queuing and braking of queuing vehicles, this paper, taking Dehua Longjin Bridge as an example, the queue length and average travel speed of the sections as evaluation index, with the Synchro simulation software for analysis and evaluation, studies the traffic signal timing optimization method of such intersections near the two ends of the bridge. On the basis of optimizing the single-point signal timing, and analysing the traffic volume and management measures in morning peak hours, a“two-directions green wave” signal coordination control optimization strategy is adopted, so as to establish an optimized signal coordination control system.
