The invention provides a sub-region division method and device of an urban road network, electronic equipment and a medium. The method comprises the following steps: acquiring first static traffic data and first dynamic traffic flow data of each intersection in a to-be-divided urban road network in a vehicle-road cooperation system; inputting the first static traffic data and the first dynamic traffic flow data of any two intersections into an inter-intersection association degree mathematical model, and determining a first association degree value between the two intersections; and carrying out sub-region division on the urban road network to be divided based on the plurality of first association degree values. Static traffic data and dynamic traffic flow data of intersections are collected in real time in a vehicle-road cooperation system, an inter-intersection association degree mathematical model obtains association degree values of the intersections according to the static traffic data and the dynamic traffic flow data, and road network subareas are dynamically divided according to the association degree values. And the accuracy of road network sub-region division is improved.

    本申请提供了一种城市路网的子区域划分方法、装置、电子设备及介质,包括:在车路协同系统中获取待划分城市路网中的每个交叉口的第一静态交通数据以及第一动态交通流数据;将任一两个所述交叉口的第一静态交通数据以及第一动态交通流数据输入至交叉口间关联度数学模型之中,确定出两个所述交叉口之间的第一关联度值;基于多个所述第一关联度值,对所述待划分城市路网进行子区域划分。通过在车路协同系统中对交叉口的静态交通数据以及动态交通流数据被实时被采集,交叉口间关联度数学模型根据静态交通数据以及动态交通流数据得到交叉口之间的关联度值,根据关联度值实现对路网子区进行动态划分,提高了路网子区域划分的准确性。
