【摘要】：为减少动态协调控制系统中因信号控制方案切换而导致系统产生的扰动,保证交通流的平稳运行,在综合考虑过渡时间和平滑特性的基础上,提出一种基于最佳相位差调整量控制方案的快速平滑过渡方法.该方法以使各交叉口相位差变化量最小为目标,优化计算得出各交叉口最佳相位差调整量,并以此为依据计算各交叉口在控制方案过渡期间的信号周期.仿真实验对比分析显示,当相位差变化量为40 s时,提出的方法与国外著名的Add和Subtract方法相比,车均延误指标分别下降了23%和11%,路网车均停车次数指标分别下降了9%和8%;此外,本文方法能够使干线协调控制方案最多通过3个信号周期快速地过渡到新方案,且过渡期间的控制效果优于Add和Subtract方法.
[Abstract]:In order to reduce the disturbance caused by signal control scheme switching in dynamic coordinated control system and ensure the smooth operation of traffic flow, the transition time and smooth characteristics are considered synthetically. A fast and smooth transition method based on the optimal phase difference control scheme is proposed, in order to minimize the change of phase difference at each intersection, the optimal phase difference adjustment quantity of each intersection is obtained by optimization calculation. The simulation results show that when the phase difference is 40 s, the proposed method is compared with the famous Add and Subtract methods. The average vehicle delay index decreased by 23% and 11 respectively, and the average stop times of road network decreased by 9% and 8 respectively. In addition, the method in this paper can make the trunk line coordination control scheme transition to the new scheme quickly through up to three signal cycles. The control effect during transition is better than that of Add and Subtract.
