The invention relates to the technical field of data processing, in particular to the technical fields of intelligent traffic, traffic management, traffic information processing and the like, and particularly relates to a traffic jam tracing method and device, electronic equipment and a storage medium. According to the specific implementation scheme, an undetermined road section and at least two reference road sections related to the undetermined road section are determined from a target road network; wherein the reference road section is a road section into which traffic flow of the to-be-determined road section can flow; acquiring a congestion infection distance between the to-be-determined road section and the reference road section in the target time period; calculating a congestion time difference between a first congestion moment of the to-be-determined road section in the target time period and a second congestion moment of the reference road section in the target time period; and under the condition that the relevancy between the congestion infection distance and the congestion time difference meets a preset relevancy requirement, determining the to-be-determined road section as a congestion source of the target road network in the target time period. According to the invention, the determination precision of the congestion source can be improved.

    本公开涉及数据处理技术领域,尤其涉及智慧交通、交通管理、交通信息处理等技术领域,具体涉及一种交通拥堵溯源方法、装置、电子设备及存储介质。具体实现方案为:从目标路网中确定待定路段,以及与待定路段相关的至少两条参考路段;其中,参考路段为待定路段的车流能够流入的路段;获取目标时段内待定路段与参考路段之间的拥堵传染距离;计算待定路段在目标时段内的第一拥堵时刻与参考路段在目标时段内的第二拥堵时刻之间的拥堵时间差;在确定拥堵传染距离与拥堵时间差之间的相关度满足预设相关度要求的情况下,将待定路段确定为目标路网在目标时段内的拥堵源头。采用本公开可以提高拥堵源头的确定精度。
