INCORPORATING RISK ANALYSIS IN MUNICIPAL HAZARDOUS MATERIALS NETWORK DESIGN

Very large, and ever-increasing amounts of hazardous materials (Hazmat) are transported daily on the transportation networks. Hazmat accidents can have very serious environmental and economic consequences. To improve the safety of Hazmat transportation, many cities restrict the roads that may be used for Hazmat trucks. Hazmat network design is to choose those arcs (roadways) to include in, or add to, the Hazmat network so that the overall environmental, social and economic cost is as small as possible while the shipping demands are satisfied. The fundamental part of Hazmat network design process is risk assessment. This paper discusses a dispersion model to calculate the distribution of air-borne pollutants in risk assessment. Computational complexity is overcome by the adoption of a raster geographic information systems (GIS) framework.
