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.
