The invention discloses a traffic period division scheme generation method and system and a storage medium, and relates to the technical field of traffic analysis, research and judgment, and the method comprises the steps: carrying out the preprocessing of flow data, repairing the missing data, and generating the preprocessed data; carrying out preliminary segmentation by adopting an ordered clustering algorithm and obtaining an initial division point sequence; carrying out smoothing processing on the preprocessed data; grouping the smoothed data according to division points, verifying the data in each group, adjusting a time division number and recalculating a division scheme according to a verification result, and performing loop iteration until a stop condition is met to obtain a final division number; and according to the final division number, carrying out final segmentation by adopting the ordered clustering algorithm again, and calculating to obtain a final time period division result. The invention further comprises a corresponding system and a storage medium. According to the traffic engineering related constraint conditions, the time period division number is iteratively optimized, and the time period division scheme meeting the actual application requirement is recommended.

    本发明公开一种交通时段划分方案的生成方法、系统及存储介质,涉及交通分析研判技术领域,方法为:对流量数据进行预处理,并对缺失数据进行修复,生成预处理后的数据;采用有序聚类算法进行初步分割并得到初始划分点序列;对预处理后的数据进行平滑处理;对平滑处理后的数据按照划分点分组,并对每组内的数据进行校验,根据校验结果进行时段划分数量的调整和划分方案的重新计算,循环迭代至满足停止条件,获得最终划分数量;根据最终划分数量,再次采用有序聚类算法进行最终分割,计算得到最终时段划分结果。还包括相应的系统以及存储介质;本发明根据交通工程相关约束条件,对时段划分数量进行迭代优化,推荐出满足实际应用需求的时段划分方案。
