The invention discloses a signal control period division method considering an extreme scene frequent period, and relates to the technical field of signal control period division, and the method comprises the steps: S1, collecting the historical traffic flow data of an intersection; s2, adopting a fisher optimal segmentation method; s3, correcting the basic signal control time period by using the total flow of the intersection, and solving the problem that the morning and evening peak division time period is too long in the division result of the fisher optimal division method; s4, on the basis of historical traffic flow data, frequent time periods of typical problems of exit lane overflow, queuing imbalance and green light empty-discharge extreme scenes in the three date states are identified; and S5, fusing the extreme scene typical problem frequent occurrence time period and the correction signal control time period. By analyzing time-varying features of historical traffic flow data and frequent features of typical problems, a signal control time period division method considering frequent time periods of extreme scenes is innovatively provided, and a plurality of signal control time periods are divided for three date states of workdays, non-workdays and holidays.

    本发明公开了一种考虑极端场景常发时段的信号控制时段划分方法,涉及信号控制时段划分技术领域,包括:S1.采集交叉口历史交通流数据;S2.采用fisher最优分割法;S3.使用交叉口总流量对基础信号控制时段进行修正,解决fisher最优分割法的划分结果中早晚高峰划分时段过长的问题;S4.基于历史交通流数据,识别三种日期状态下出口道溢出、排队不均衡以及绿灯空放极端场景典型问题的常发时段;S5.融合极端场景典型问题常发时段和修正信号控制时段。通过分析历史交通流数据的时变特征和典型问题的常发特征,创新地提出了一种考虑极端场景常发时段的信号控制时段划分方法,对工作日、非工作日和节假日三种日期状态划分多个信号控制时段。
