The invention provides a traffic path tracing method, device and equipment and a storage medium, and the method comprises the steps: obtaining the OD data and the navigation path data between the origin and destination of the OD, endowing the path attribute information according to the navigation data, constructing a path impedance function, constructing a path selection probability function, obtaining the path selection probability, and carrying out the tracing of a traffic path. And according to the path selection probability and the traffic flow, allocating path traffic flow, finally traversing the path passing through the road section through spatial proximity, and according to the path traffic flow of the corresponding path, obtaining a traceability analysis result of the target road section. According to the method, the road impedance function is constructed through the path attribute data, the method better fits the actual road network state and is different from the mode of counting the flow from non-collection data, the OD flow is distributed to the paths firstly, then the road section flow is obtained through path aggregation, track processing of a single traffic entity is not involved, the data processing flow is simplified, and the data processing efficiency is improved. And the traffic path traceability analysis efficiency is improved.

    本发明提供了一种交通路径溯源方法、装置、设备及存储介质,通过获取OD数据和OD起讫点之间的导航路径数据,再根据导航数据赋予路径属性信息,构建路径阻抗函数,进而构建路径选择概率函数,并获取路径选择概率,再根据路径选择概率与交通流量,分配路径交通流量,最后通过空间临近性遍历途径该路段的路径,并根据相应路径的路径交通流量,获取目标路段的溯源分析结果。本发明通过路径属性数据构建道路阻抗函数,更贴合实际路网状态,且区别于从非集计数据统计流量的模式,先将OD流量分配至路径,再由路径聚合得到路段流量,不涉及单个交通实体的轨迹处理,简化了数据处理流程,提升了交通路径溯源分析效率。
