Future quantities and routings of hazardous materials shipments were projected for the year 2000, on the basis of the results of previous arizona transportation surveys. Projections were made of internal shipments of gasoline, propane, and acids. Interstate shipments, hazardous waste, and non bulk shipments were also projected. Routing maps of arizona depicting the projected shipments were then created. A data base information system was developed to store hazardous waste shipment data for the year 1986, and information from this data base was used to project volumes and routings of these shipments. Despite the uncertainties, the effects of new regulations and waste minimisation activities were incorporated. Similar projection routing maps were developed for hazardous materials. The results provide a picture of future hazardous materials transportation on arizona highways and a basis for conducting risk analysis. Methodological issues and data availability problems are addressed to model projections at the state level.
