The invention discloses an emergency power supply configuration method considering road traffic dynamic characteristics, and the method comprises the following steps: S1, constructing a generalized regression neural network in combination with the historical data or real-time data of road traffic flow, and predicting the dynamic traffic flow of a certain time period in the future; s2, defining a road dynamic traffic index to describe the dynamic characteristics of the road, and calculating the road dynamic traffic index according to the actual length of the road, the congestion time and the predicted traffic flow; s3, taking the road traffic indexes as a weight matrix of a Dijkstra algorithm, and performing optimal path search; and S4, through the selected optimal path, the power grid fault location is reached, a forward-backward substitution method is combined, the distribution network power flow is calculated, and the installation position of the emergency power supply is determined. According to the method
