The invention provides a traffic signal control multi-period division method and related equipment. The method comprises the following steps: creating a south-north stage combination scheme library and an east-west stage combination scheme library; acquiring historical traffic flow data in a plurality of first time periods, counting the average traffic flow to obtain a flow structure, and respectively calculating each stage combination scheme in the south-north stage combination scheme library and the east-west stage combination scheme library through the flow structure to obtain a plurality of stage combination schemes in the south-north stage combination scheme library and the east-west stage combination scheme library; obtaining a south-north and east-west phase combination scheme, a phase duration and a period value in each first time period; setting a threshold value, calculating a difference value between the period value of the stage combination scheme of the first time period and the period value of the stage combination scheme of the adjacent time period, judging the size of the period difference value and the threshold value, and selecting to reserve or replace the stage combination scheme of the first time period; grouping and clustering the stage combination schemes, the period values and the stage duration values of all the first time periods to obtain division schemes; the problems of untimely transition and inflexible phase stage in the prior art are solved.

    本发明提供了一种交通信号控制多时段划分方法及相关设备,通过创建南北向、东西向阶段组合方案库;获取在多个第一时段中的历史交通流数据,并统计平均交通流量,得到流量结构,通过流量结构分别对南北向阶段组合方案库、东西向阶段组合方案库中的各个阶段组合方案进行计算,得到在每个第一时段中南北向、东西向的阶段组合方案、阶段时长及周期值;设置阈值,计算第一时段的阶段组合方案的周期值与相邻时段的阶段组合方案的周期值之间的差值,判断周期差值与阈值的大小,选择保留或替换第一时段的阶段组合方案;对所有第一时段的阶段组合方案、周期值及阶段时长值进行分组和聚类,得到划分方案;解决现有技术过渡不及时、相位阶段不灵活的问题。
