The invention relates to an urban road intersection time period division method and a storage medium. The method comprises the following steps: acquiring multi-dimensional data of a fixed-point intersection; aggregating the historical data, and calculating the hour traffic volume; the real hour traffic is calculated by adopting a moving average method for the hour traffic, and data of sliding center time granularity is replaced after calculation; selecting to divide the intersection data, the intersection branch data and the steering data according to actual signal optimization requirements; and performing division by using an improved fisher optimal division algorithm to obtain an optimal division result. According to the invention, on the basis of flow data collected by urban traffic flow monitoring equipment, a refined time period division result of an urban intersection signal control scheme is calculated more quickly and conveniently, and continuous time periods close to traffic passing demands at intersections are converged, grouped and classified; signal control optimization timing is carried out on more stable data in a current period subsequently, signal control is carried out by using the same timing scheme, and space-time resources of an intersection signal machine are fully utilized.

    本发明的一种城市道路交叉口时段划分方法及存储介质,其方法包括定点交叉口多维数据采集;对历史数据聚合,计算小时交通量;小时交通量采用滑动平均方法计算真实小时流量,计算后替代滑动中心时间粒度的数据;根据信号优化实际需求,选择对路口数据、路口分支数据、转向数据进行划分;使用改进的fisher最优分割算法划分得到最优划分结果。通过本发明依托城市交通流量监测设备采集到的流量数据,更加快速便捷的计算出城市路口信号控制方案的精细化时段划分结果,对路口连续的交通通行需求接近的时段汇聚分组划类,后续对此时段内更为稳定的数据进行信号控制优化配时,使用同一套配时方案进行信号控制,充分利用交叉口信号机的时空资源。
