Development of Criteria to Designate Routes for Transporting Hazardous Materials

摘要

The purpose of this report is to document the results of an investigation of hazardous materials transport by truck and to develop criteria to designate routes for hazardous materials movements. Section 1 introduces, reviews, and summarizes the hazardous materials (HM) routing problem. Section 2 documents the steps taken--from the development of route selection factors to the selection of models used--to predict the probability of an HM accident. The documentation consists of: an examination of federal, state, and a limited number of local laws and regulations; an indication of which factors should be considered for route selection; and the development of a procedure to determine the probability of an HM accident on routes considered for the transport of HM. Section 3 develops a methodology which can be used to assess the consequences of an HM accident; primary factors considered are population and property exposure. Section 4 combines the results of Sections 2 and 3 into a risk assessment methodology which quantitatively indicates routes having more or less risk associated with the transport of HM; criteria are also presented for designating HM routes. Section 5 presents the results of applying the HM risk methodology in two jurisdictions and assesses the utility of the methodology.
