Abstract: To solve the limitation and complexity of optimizing algorithms for post-earthquake routes selection, an improved route selection method for post-earthquake was proposed based on earthquake disaster prediction about urban road system, according to the repair time of road system. With the support of Geographic Information System (GIS) and database technologies, the system of routes optimization was developed by using the road system of CQUPT (ChongQing University of Posts and Telecommunications). According to the system, the emergency decisionmakers can get the dynamic state of road system after the earthquake. Also, the routes optimization can be supplied for the rescues to get the scene and to transfer the wounded and resources.
