The invention relates to the technical field of intelligent traffic control, in particular to a method and a device for dividing traffic control multistage subareas. The objective of the invention isto solve the problems of unreasonable single-stage sub-region division, low sub-region flow similarity and redundant nodes in sub-regions. The method comprises the following steps: when the number ofnodes in a K-level subarea is greater than a preset threshold, dividing the K-level subarea through a self-defined spectral clustering function to obtain a K + 1-level subarea; removing redundant nodes, relative to the K-level subarea, in the K + 1-level subarea to obtain a final K + 1-level subarea; based on the final K + 1-level subarea, judging that the K-level subarea has an undivided subarea,and repeating the steps until the division of all the K-level subareas is finished; otherwise, outputting a final K + 1-level sub-region division result.

    本申请涉及智能交通控制技术领域,特别地,涉及一种划分交通控制多级子区的方法及装置。为了解决单级子区划分不合理、子区流量相似度低、子区存在冗余节点的问题。所述方法包括:K级子区的节点数量大于预设阈值时,通过自定义谱聚类函数对所述K级子区进行划分得到K+1级子区;去除所述K+1级子区内相对于所述K级子区的冗余节点,得到最终K+1级子区;基于所述最终K+1级子区,判定所述K级子区存在未划分子区,则重复上述步骤直至全部子K级子区划分结束;否则,输出最终K+1级子区划分结果。
