Abstract:

      This paper establishes a route choice model with the maximum risk constraint based on the definition of hazmat material transportation risk. The model takes into account the effect of the social vehicles on the travel time of hazmat shipments and the total risks of transportation network. We design a corresponding particle swarm optimization algorithm to solve the model. We eventually use numerical examples to analyze the effectiveness of the model and the algorithm. Computation results show that the consideration of the maximum risk constraint can significantly decrease the total transportation network risks of the hazmat shipments.

Key words: hazmat shipments, route decision, particle swarm optimization algorithm
