The embodiment of the invention provides an intersection phase sequence optimization method and device, equipment and a storage medium. The method comprises the following steps: traversing an optional phase sequence of an intersection; for each selectable phase sequence, obtaining an intersection signal control optimization index under the phase sequence according to a flow direction evaluation index of the intersection, and obtaining a signal control timing scheme according to the optimization index, the signal control optimization index including an intersection green light utilization rate and a stage green signal ratio of the intersection in each stage; determining the scheme saturation after the credit control timing scheme is operated; and selecting a target phase sequence and a corresponding credit control timing scheme according to the scheme saturation. According to the technical scheme provided by the embodiment of the invention, the green light time and the signal control period of each stage of the intersection are optimized, the optimal phase sequence is selected according to the saturation of the scheme, and the traffic fluency of the intersection is improved.
