信号交叉口车辆排队统计方法研究

信号交叉口排队控制的关键在于排队统计.以排队检测器和感应检测器为硬件基础,检测进口车辆排队状态,设计排队统计逻辑对采集的实时信息做出规整,建立排队统计方法,为信号机提供准确的路口排队信息,提高排队控制效果.应用Vissim交通仿真软件对排队统计策略进行仿真分析,结果表明,交叉口排队信息优化了配时方案,减少了绿灯损失时间、停车次数和延误,完善了智能交通控制效果.

Study on Vehicle Queue Statistics Methods of Signalized Intersections

Queue statistics is the key point of the signalized intersection queue control. Tak- ing the queuing detector and inductive detector as hardware basis, this paper detects the incoming vehicle queue situation, designs the queue statistics logic, adjusts the real-time information,sets up the queue statistics method and provides the accurate queue information of the intersections for the signaler so as to raise the effect of the queue control. The Vissim traffic simulation software is used to analyze the vehicle queue statistics strategies, as a result, the queue data of intersections can optimize the timing program and reduce the loss of the green light, parking times and delays, which can perfect the intelligent traffic control.
