GUIDELINES FOR APPLYING CRITERIA TO DESIGNATE ROUTES FOR TRANSPORTING HAZARDOUS MATERIALS. IMPLEMENTATION PACKAGE

Techniques are explained that may be used for evaluating alternative highway routes for hazardous materials movements. The criteria that may be applied for hazardous materials routing is briefly described and their application is illustrated by an example. Current routing practices, with existing regulatory requirements, are described as background. An overview of the routing method is followed by a description of the guidelines and procedures for applying the routing criteria. The concept of risk is defined and each step in the route selection explained. A hypothetical case study illustrates the application of the routing procedures; the example includes personal and property risk calculations and illustrates the techniques for analyzing urban arterials and rural highways. Blank worksheets and forms for structuring and conducting the routing analyses are appended.
