| 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 eliminate disturbances caused by traffic signal transition and ensure smooth traffic flow in dynamic coordination control system, in view of transition time and smoothing characteristics, a fast smoothing transition method was proposed based on the optimization of offset adjustment. This method intends to minimize offset difference for each intersection, calculates the optimal offset adjustments, and further computes signal interval during the transition of coordination control plans. The simulation analysis shows that when the amount of offset adjustment is 40 s, the proposed method, in contrast to Add and Subtract methods, can decrease average vehicle delay by 23% and 11%, and average number of stops by 9% and 8%. Furthermore, the proposed method can ensure transition time no more than 3 signal intervals, and its control performance is better than those of Add and Subtract methods. |
