The invention provides a traffic knowledge graph construction method and device, equipment and a storage medium, relates to the technical field of intelligent traffic, and can construct a traffic knowledge graph used in the field of traffic signal control so as to facilitate employees to deal with various traffic signal control problems. The method comprises the following steps: acquiring phase sequences of a plurality of traffic signals; aiming at the phase sequence of each traffic signal in the plurality of traffic signals, determining a direction phase sequence of the phase sequence, and obtaining a traffic phenomenon existing in the direction phase sequence, a reason causing the traffic phenomenon, and a solution strategy of the reason; constructing a traffic knowledge graph according to the phase sequence of each traffic signal, the direction phase sequence of the phase sequence, the traffic phenomenon under the direction phase sequence, the cause of the traffic phenomenon and the solution strategy of the cause; the traffic knowledge graph is used for analyzing the traffic signal control problem between the nodes or between the nodes and the edges. The method can be used in the process of diagnosing the traffic signal control problem.

    本申请提供一种交通知识图谱的构建方法、装置、设备及存储介质,涉及智能交通技术领域,可以构建用于交通信号控制领域的交通知识图谱,方便从业人员应对各种交通信号控制问题。该方法包括:获取多个交通信号的相位相序;针对多个交通信号中每个交通信号的相位相序,确定相位相序的方向相位相序,获取在方向相位相序下存在的交通现象,导致该交通现象的原因,该原因的解决策略;根据每个交通信号的相位相序,相位相序的方向相位相序,方向相位相序下存在的交通现象,导致该交通现象的原因和该原因的解决策略,构建交通知识图谱;交通知识图谱用于分析节点间或节点与边间的交通信号控制问题。本申请可用于诊断交通信号控制问题的过程中。
