A time period division optimization method of an urban road intersection multi-time-period signal control scheme comprises the steps that starting from queuing evacuation time of an entrance flow direction hierarchy, a phase corresponding to the minimum time granularity, the air release rate of the flow direction and the unbalance rate are calibrated; and the green-time utilization condition of adjacent time intervals in different flow directions and the demand imbalance condition of different flow directions in the same phase are anlayzed, and the feasibility of merging the adjacent time intervals is judged on the basis. By means of multiple analysis and combination, an original time period division scheme is optimized, the signal optimization goal under the intersection unsaturated and saturated supersaturated states is met, and therefore signal control time period division higher in reliability and stability is achieved.

    一种城市道路交叉口多时段信号控制方案的时段划分优化方法,从进口流向层级的排队疏散时间着手,对最小时间颗粒度对应的相位、流向的空放率、失衡率进行标定,进而分析相邻时间间隔在不同流向的绿时利用情况以及同一相位内不同流向的需求失衡情况,在此基础上研判相邻时间间隔合并的可行性。通过多重分析与合并,对原始时段划分方案进行优化,满足路口非饱和以及饱和过饱和状态下的信号优化目标,从而实现可靠性更高、稳定性更强的信控时段划分。
