【摘要】：针对现有干线交通信号绿波控制方法采用平行等宽的绿波带宽,无法考虑相邻交叉口间交通流运行速度波动性的缺陷,引入了基于路段速度波动区间的不等绿波带宽,提出了干线交通双向绿波优化控制方法.该方法在满足非绿波相位交通需求的前提下,以相邻交叉口之间的绿波带宽最大化为优化目标,通过构建带宽最大化模型,调整相邻交叉口之间的相对相位差,并以重叠度检验为约束条件,防止了绿波带断层现象的产生,进而实现了干线道路交通信号的双向绿波控制.以昆山市长江路为例,基于效率层面的评价指标对提出的干线交通双向绿波优化控制方法性能进行评估,结果表明:该方法较之传统的绿波控制方法在绿波带宽方面增加了11.8%,在交通延误和车辆排队长度方面分别减少了15.34%和10.86%.
[Abstract]:Aiming at the disadvantage of the existing green wave control methods of trunk road traffic signal using parallel and equal width green wave bandwidth, which can not take into account the fluctuation of traffic flow speed between adjacent intersections, the unequal green wave bandwidth based on section velocity fluctuation interval is introduced. In this paper, a bi-directional green wave optimal control method for trunk line traffic is proposed. Under the premise of satisfying the requirement of non-green wave phase traffic, the optimization goal is to maximize the green wave bandwidth between adjacent intersections, and a bandwidth maximization model is constructed. The relative phase difference between adjacent intersections is adjusted, and the overlap test is taken as the constraint condition to prevent the occurrence of the fault in the green wave zone, thus realizing the two-way green wave control of traffic signals on the trunk roads. Taking the Changjiang Road in Kunshan City as an example, Based on the evaluation index of efficiency level, the performance of the proposed bi-directional green wave optimal control method for trunk traffic is evaluated. The results show that compared with the traditional green wave control method, the proposed method increases the green wave bandwidth by 11.8%, reduces the traffic delay and vehicle queue length by 15.34% and 10.86 respectively.
