The invention relates to an emergency vehicle travel road impedance measuring and calculating method in a network connection traffic environment. The method comprises the following steps: step 1, establishing a vehicle state information matrix of an emergency vehicle travel path space; 2, constructing an emergency vehicle travel road section impedance model; 3, constructing an emergency vehicle travel intersection delay model; and step 4, generating a lane-level emergency vehicle travel road impedance model. According to the method, the road impedance borne by the emergency vehicle in the travel process in the network connection traffic environment can be accurately measured and calculated, a theoretical foundation is laid for travel path planning of the emergency vehicle, and the method is suitable for global optimization control of the emergency vehicle in the network connection traffic environment and has a wide application prospect. The method is subsidized by the natural science fund project (PL2024E012) of Heilongjiang Province.
