The embodiment of the invention provides a traffic flow tracing method, device and equipment and a storage medium, and relates to the technical field of data processing, and the method comprises the steps: determining target snapshot equipment corresponding to a target road section, and obtaining a plurality of target license plate numbers based on the target snapshot equipment; a distributed parallel processing mode is adopted, trip chains corresponding to the multiple target license plate numbers in the preset time period are obtained, and the trip chains are sequentially composed of multiple upstream road section identifiers reaching the target road section. And for any upstream road section identifier, carrying out statistics on the trip chain containing the upstream road section identifier to obtain the traffic flow corresponding to the upstream road section identifier. And finally, taking the plurality of upstream road section identifiers and the respective corresponding traffic flow as a traffic flow tracing result of the target road section. The traffic flow traceability result is determined through the traffic flows of the upstream road sections, and the accuracy of the traffic flow traceability result is improved.

    本申请实施例提供了一种交通流溯源方法、装置、设备及存储介质,涉及数据处理技术领域,该方法包括:确定目标路段对应的目标抓拍设备,并基于目标抓拍设备获取多个目标车牌号码。再采用分布式并行处理的方式,获取多个目标车牌号码在预设时段内各自对应的出行链,其中,出行链是由到达目标路段的多个上游路段标识依序组成。针对任一上游路段标识,对包含上游路段标识的出行链进行统计,获得上游路段标识对应的车流量。最后,将多个上游路段标识以及各自对应的车流量,作为目标路段的交通流溯源结果。通过多个上游路段的车流量确定交通流溯源结果,提高了交通流溯源结果的准确性。
