以绿波带最大化为目标,利用干线协调控制的时空分析图,结合经典算例,从绿信比损失、理想信号间隔取值范围和迭代步长等角度出发,通过设置假想距离在数解法中考虑车辆实际运行中的延误情况,并设计最优理想信号间隔搜索方法,提出了一种新的通过带宽度计算方法。研究结果表明:考虑行车延误的干线协调控制信号配时数解算法,比经典算法求得的通过带宽度更大,计算得到的最佳公共信号周期与通过带宽度也更为准确。
Taking the maximization of the green wavelength band as the goal, using the spatiotemporal analysis diagram of the coordinated control of the main line, combined with the classical example, from the viewpoints of the loss of green signal, the range of ideal signal interval and the iteration step, Considering the delay in the actual operation of the vehicle and designing the optimal ideal signal interval search method, a new method for calculating the passing bandwidth is proposed. The results show that the algorithm of calculating the number of timing coordination of the trunk coordinated control signal considering traffic delay is more accurate than the passband obtained by the classical algorithm and the calculated optimal common signal cycle and passband width are more accurate.
