Traffic flow coordinated regulation and control method for priority passing of emergency vehicles in intelligent network connection environment

The invention discloses a traffic flow coordinated regulation and control method for priority passage of emergency vehicles in an intelligent network connection environment, which is suitable for priority passage of emergency vehicles on a basic road section of a road, and is characterized in that all vehicles running on the road are network connection automatic driving vehicles in the intelligent network connection environment. According to the method, a corresponding vehicle and surrounding vehicles are timely controlled to cooperate with each other to complete cooperative lane changing according to the relation between the moving safety interval of the emergency vehicle and the headstock distance of a front vehicle, so that priority passing of the emergency vehicle is guaranteed; the vehicles on the upstream road section of the emergency vehicles are regulated and controlled by taking flow balance and spacing balance as regulation and control principles, so that the upstream traffic flow of the emergency v
