The embodiment of the invention discloses a special vehicle signal priority control method and device based on vehicle-infrastructure cooperation, relates to the technical field of intelligent traffic, and can guarantee the priority passage of special vehicles. Comprising the steps that traffic data information of an intersection is acquired in real time, and the traffic data information comprises the number of vehicles in all directions of the intersection, the queuing length and the vehicle type; when it is determined that the type of the captured vehicle is a special vehicle according to the traffic data information, traffic lights are controlled to enter an emergency stage; the emergency stage is a special vehicle priority passing stage; controlling the phase of a traffic light according to a preset algorithm in the emergency stage to enable the special vehicle to pass preferentially; and after the special vehicle passes, controlling the traffic light to enter a normal stage, wherein the normal stage is a stage of normal switching of traffic light signals. The method is suitable for special vehicle passing scenes.
