Hazardous chemical transport route planning method and device

The invention discloses a hazardous chemical transport route planning method and device, and belongs to the field of hazardous chemical transport. The method comprises the following steps: information of a plurality of routes to be selected between a departure place and a destination is acquired, and the information of the routes to be selected includes sections which form the routes to be selected; the analytic hierarchy process is used to determine a weight vector of each factor affecting hazardous chemical transport, and the weight vector is used to quantitatively describe the relative importance among the factors; the value of each factor in each section is acquired; the value of influence of each route to be selected on hazardous chemical transport is determined according to the weight vector of each factor, the value of each factor in each section and the information of the routes to be selected; and a route to be selected, which has the smallest impact value is output. Through the adoption of the method and device provided by the invention, routes for hazardous chemical transport planning can be obtained.
