A vehicle routing problem of hazardous materials transportation is studied in this paper. Firstly, the maximum permissible flow of the road section is calculated according to the social risk and accident rate values. Secondly, based on the structural measures and basic transportation network, the maximum permissible flow of the road section is taken as road section capacity, the minimum risk is taken as general minimum cost , and a minimum cost and maximum flow method is introduced to solve the flow distribution problem of hazardous materials transportation. Finally, the effectiveness of the method is illustrated with a simple numerical example.

Core Theory

The transportation network dynamic port and the correlation question are in the intelligence transportation system the transportation flow the induction the core theory. This article has first studied the immediate road section transportation time dynamic user most superior assignment characteristic and the road section equation of state, and has established the immediate road section transportation time dynamic user most superior assignment model. In the third part, mainly discussed but should grasp for the time discrimination and the Frank-Wolfe algorithm which the solution immediate dynamic user route selection model; the article finally uses the example through the test, to the model which establishes has carried on the simulation.
