The invention provides an urban road network dynamic division method and device, computer equipment and a storage medium. According to the method, potential traffic state modes and multi-dimensional change characteristics in road network traffic state data are deeply mined, the traffic space-time correlation and the connectivity of the space structure of the road network are introduced, and dynamic division is carried out on the road network, therefore, each sub-road network has similar spatio-temporal evolution characteristics, the difference of traffic modes among the different sub-road networks is maximized, scientific division of the large-scale road network can be realized, and the fine management level of the road network is improved. The method can be used for intelligent traffic control of the large-scale road network, and adopts real-time traffic guidance and control strategies for the different sub-road networks, thereby realizing macroscopic regulation and control of traffic flow of the whole road network, and providing basic technical support for an intelligent traffic system driven by data.
本发明提供一种城市路网动态划分方法、装置、计算机设备和存储介质,该方法通过深入挖掘路网交通状态数据中潜在的交通状态模式和多维度变化特征,并引入交通时空相关性和路网空间结构的连通性,进而进行路网动态划分,从而使得每个子路网具有相似的时空演化特征,最大化不同子路网之间交通模式的差异,可以实现对大规模路网的科学划分,提高路网的精细化管理水平。可以用于大规模路网的智能交通管控,针对不同的子路网采取实时的交通诱导和控制策略,从而实现对整体路网交通流的宏观调控,为数据驱动下的智能交通系统提供基础技术支撑。
