摘要
针对多目标雷达检测器可以获取区域交通状态的特点,提出了一种基于多目标雷达数据的单点交叉口信号控制方法。首先,根据进口道检测区域排队长度情况,设计了单点信号控制策略,将单点信号控制划分为两个阶段。其次,分别确定两个阶段的信号控制方法。第一阶段主要解决常规车辆放行问题,建立了信号相位的切换规则。第二阶段主要解决进口道车辆排队过长以及出口道排队溢出问题,建立了相应的控制逻辑规则。在此基础上,确定了相关控制参数的取值与优化方法。最后,以实际典型交叉口为例对本文构建的控制方法进行仿真验证。结果表明,本文控制方法可以有效提升交叉口运行效率,平均车辆延误降低了9%,高交通需求下车辆排队长度降低了15.5%。
Aiming at the characteristics that the multi-target radar detectors can obtain the regional traffic performance,a signal control method at isolated intersections was r proposed based on multi-target radar data.First,according to the queue length of the detection area at the approach,a signal control strategy at isolated intersections is designed,and the signal control method is divided into two stages.Secondly,the signal control methods of the two stages are determined respectively.The first stage mainly solves the problem of conventional vehicle release,and establishes the signal phase transfer rule.The second stage mainly solves the problem of excessively long queues of vehicles at the approach and overflow of queues at the exit.The corresponding control logic rules are established.On this basis,the value and optimization method of related control parameters are determined.Finally,the actual typical intersection is taken as an example to simulate and verify the proposed signal control method.The results show that the proposed signal control method in this paper can effectively improve the operation efficiency of the intersection,the average vehicle delay is reduced by 9%,and the vehicle queue length under high traffic demand is reduced by 15.5%.
