The invention provides a traffic signal lamp phase acquisition method and device and a medium, and relates to the technical field of traffic control. The method comprises the steps that if it is determined that a target phase obtaining condition is met currently, vehicle information corresponding to a traffic flow of an intersection is obtained according to the met target phase obtaining condition, and the vehicle information comprises the total number of vehicles, the number of vehicles with different priorities, the vehicle speed and the waiting duration; the target phase acquisition condition comprises at least one of initialization completion, a current phase being a standard phase and the standard phase being in a switchable time period; and calculating a weight corresponding to the traffic flow according to the vehicle information, and determining a to-be-displayed target phase of the traffic signal lamp based on a corresponding relationship between the traffic flow and the phase and the weight. According to the embodiment of the invention, the actual road condition of the intersection can be obtained, the phase displayed by the traffic signal lamp is flexibly adjusted according to the actual intersection, the suitability of the phase and the actual road condition is improved, traffic congestion is effectively avoided, and the traffic smoothness and the traffic efficiency are improved.
