Abstract: Emergency rescue dispatch should be efficient, timely and convenient to start emergency rescue dispatch when an accident occurs, so as to achieve as little loss as possible, but in the specific implementation, rescue equipment, rescue teams, rescue routes and other information can not be quickly determined, resulting in significant loss of life and safety of people and property. The article takes municipal road emergency resource scheduling as the background, conducts AHP (Analytic Hierarchy Process) hierarchical analysis on each impedance factor, and uses the shortest path Dijkstra algorithm for modelling to solve the optimal path for emergency resource scheduling of municipal traffic road networks. ArcGIS software is used to create a network analysis network model,and the Dijkstra shortest path algorithm is used to model the optimal path selection for emergency resource dispatching, making it more relevant to improve emergency rescue capabilities, and combined with practical examples to verify the feasibility of the GIS-based optimal path analysis solution for road emergency resource dispatching, providing the optimal path selection for urban road traffic emergency resource dispatching decision support.
