The invention discloses a traffic period division method. The method comprises the following steps: acquiring collected continuous historical traffic flow of each entrance lane of a specified intersection; constructing an ordered sample sequence of which the time span is one day according to the continuous historical traffic flow; performing ordered clustering on the ordered sample sequence to obtain a traffic period division result; merging the sample contained in the last traffic time period in the traffic time period division result into the first traffic time period; and combining the traffic time periods with the time period span smaller than the preset span in the traffic time period division result into the adjacent traffic time period. A day ordered sample is constructed by using actual traffic flow, a scientific and reasonable traffic period division result is obtained by performing ordered clustering on the ordered sample, and furthermore, a plurality of periods of the traffic period division result are combined in combination with expert experience, so that the accuracy of traffic period division is improved. And therefore, refined treatment of the signalized intersection is satisfied, and the traffic efficiency of the signalized intersection is improved.
本发明公开了一种交通时段划分方法,方法包括:获取已采集的指定交叉口的各个进口道连续的历史车流量;根据连续的历史车流量构造时间跨度为一天的有序样本序列;对有序样本序列进行有序聚类以获得交通时段划分结果;将交通时段划分结果中的最后一个交通时段包含的样本合并到第一个交通时段中;将交通时段划分结果中时段跨度小于预设跨度的交通时段合并到与其相邻的交通时段中。通过使用实际车流量构造出一天的有序样本,并通过对有序样本进行有序聚类得到科学合理的交通时段划分结果,进一步地,结合专家经验对交通时段划分结果的若干时段进行合并,以提高交通时段划分的精准度,进而满足信号交叉口的精细化治理,提高信号交叉口通行效率。
