An improved hazardous material road transportation accident rate analysis model

Hazardous material road transportation routing based on risk analysis is one of the key methods that can achieve the reduction of hazardous material transportation risks and accident damages. The precondition of routing is the quantitative analysis of risk of every segment of road, of which the considered elements include injuries and fatalities, cleanup costs, property damage, evacuation, product loss, traffic incident delay, and environmental damage. Injuries and fatalities is regarded as the most important element, of which the precondition is the hazardous material road transportation accident rate analysis. This paper improved the traditional hazardous material road transportation accident rate analysis model through a careful analysis prior to the use of historical data, to achieve a more accurate accident rate. Historical data proved that the improved model can get results more close to the actual situation.
