The invention provides a path flow determination method and device, electronic equipment and a storage medium, and relates to the field of artificial intelligence, in particular to the fields of automatic driving, intelligent traffic and the like. According to the implementation scheme, first data associated with a vehicle driving track and second data associated with road monitoring in a selected road network area within a preset time period, and a path set associated with a specified intersection in the road network area are obtained; performing path integrity expansion on the path set based on the first data to obtain a first expanded path set; based on the second data, weighting a traffic matrix representing initial starting point-terminal point traffic of the road network area to obtain a weighted traffic matrix; determining an initial path traffic corresponding to the first extended path set based on the weighted traffic matrix; and updating the initial path flow to obtain an updated path flow based on a first diverted flow determined via the second data and a second diverted flow determined via the initial path flow.

    本公开提供了一种路径流量确定方法、装置、电子设备及存储介质,涉及人工智能领域,尤其涉及自动驾驶、智能交通等领域。实现方案为获取选定的路网区域在预设时段内与车辆行驶轨迹相关联的第一数据和与道路监控相关联的第二数据,以及与路网区域内的指定交叉口相关联的路径集;基于第一数据,对路径集进行路径完整性扩充以得到第一扩充路径集;基于第二数据,对表征路网区域的初始起点‑终点流量的流量矩阵进行加权以得到经加权的流量矩阵;基于经加权的流量矩阵,确定与第一扩充路径集相对应的初始的路径流量;以及基于经由第二数据确定的第一转向流量以及经由初始的路径流量确定的第二转向流量,对初始的路径流量进行更新以得到更新的路径流量。
