Route optimization model for urban hazardous material transportation based on Arc GIS

In order to arrange the route for the hazardous material transportation (Hazmat) reasonably to reduce the harm risk brought by the accidents of Hazmat, a route optimization model was established based on the Arc GIS with the special analysis tool such as buffer. The influence factors in urban Hazmat and the risk expenses on a road section were analyzed. The urban road network in Changchun city was taken as research object, and the model was validated by an actual accident case The results show that the route optimized by the model is reasonable, and its graphic display is valuable for the Hazmat supervisors.
