Study on the Transportation Route Decision-Making of Hazardous Material Based on N-Shortest Path Algorithm and Entropy Model

The transportation accident of hazardous materials possibly causes heavy personnel casualties, long-term environmental pollution and huge economic losses, the public and the media are very sensitive to the accident. Selecting the reasonable transport route is of great significance for the prevention of accidents. Aiming at hazardous materials highway transportation network, this paper proposed the definition of integrated transport costs and integrated danger coefficient firstly, then the N-shortest path algorithm was used to determine the alternative transportation route parameter of hazardous materials, thirdly, the algorithm steps of finding the best transportation route were constructed through using entropy model, finally an example demonstrated the feasibility of the decision-making method. This decision-making method can help the government relevant authority and the transport enterprises choose the reasonable transportation route.
