Consequence Based Route Selection for Hazardous Material Cargo: GIS-Based Time Progression of Environmental Impact Radius of Accidental Spills

The aim of this study was to investigate the transportation networks in order to identify the most suitable routes for transporting hazardous material cargoes. The potential key contribution of the study is the development of a decision tool to assist in comparing and selecting highway routes to transport hazardous materials. This research considered criteria in order to evaluate each link in the transportation network including health risks and cost of delay as a result of an en route accidental release of hazardous materials; as well as proximity to public places, and travel cost. The Gaussian air dispersion model was employed to estimate the extent of health risk protective zones and the possible affected population. Queuing analysis was utilized to calculate delay time and accordingly the associated cost. Public places with high occupation around the road segments were identified and assigned to the road segments. Trucking costs were calculated based on the length of the links and the cost per unit length. After evaluating the networks, the tool then identifies the best route in regards to the criteria using a Multi-Criteria-Decision-Making method. The results of this study can effectively aid decision makers and hazardous materials transportation companies in understanding the conflicting nature of transporting and routing hazardous cargoes in view of the decision criteria for selecting the routes and evaluating possible consequences in case of accidental releases.
