The Study of the Dangerous Goods Transport Subsidies in the Traffic Network

In the transportation network has a special transportation problem, is the problem of transport of dangerous goods, we all know that transport of dangerous goods in the event of accident, caused the harm is far greater than ordinary traffic accident, so the study of the transport is crucial. In this paper, considering the risk equilibrium, turning it into a bi-level programming problem, and then use particle swarm optimization algorithm to work out, it is concluded that increasing government subsidies can reduce the total risk and the time cost and increase network network requirements under the condition of the conclusion of present a tendency of increasing time cost. These results provide theory basis for dangerous goods transportation decisions for the government, so as to improve the safety of the transport of dangerous goods. Limited to the length and capacity, the number of dangerous goods vehicles ratio and the influence of social factors such as vehicles in the morning and evening peak level remains to be further research.
