"This report presents a user-friendly guidebook to support risk assessment, emergency response preparedness, resource allocation, and analyses of hazardous commodity flows across jurisdictions. The guidebook, which updates the U.S. Department of Transportation's "Guidance for Conducting Hazardous Materials Flow Surveys," is targeted at transportation planning operations staff at the local and regional levels, as well as local and regional personnel involved in hazardous materials training and emergency response. All modes of transportation, all classes and divisions of hazardous materials, and the effects of seasonality on hazardous materials movements are discussed."--publisher's description.

This synthesis will be of interest to staff of state departments of transportation responsible for highway routing, traffic engineering, traffic operations and signing, and maintenance. It will also be useful to state police, who may also be responsible for routing, and other enforcement personnel, as well as to emergency and fire personnel. The trucking industry will also find the information of value to their operations. Information is presented on the current practices of states for the highway routing of vehicles that transport hazardous materials. The Federal Highway Administration (FHWA) in 1994 issued Guidelines for Applying Criteria to Designate Routes for Transporting Hazardous Materials, which are used by agencies that elect to designate such routes. This report of the Transportation Research Board is based on information obtained from a survey of states concerning the routing of hazardous materials vehicles that asked respondents to rate the importance of 24 factors in the categories of roadway, environment, population, or other criteria in establishing routing policy. The survey also identified the principal agencies responsible for routing, as well as other agencies that typically participate in the routing plan. Enforcement and cost issues are discussed, as is risk assessment. This report presents a unique discussion of the issues as identified by interviews with trucking trade associations and other organizations involved with hazardous materials transport. In addition, technology applicable to more effective monitoring and enforcement is described. The appendices include commodity flow studies and route designation case studies for selected jurisdictions.

Leon N. Moses In June 1991, the Transportation Center at Northwestern University sponsored Hazmat Transport '91: A National Conference on the Transportation of Hazardous Materials and Wastes. The faculty associated with the center were aware that there had been many professional, industrial and government conferences and meetings on the subject. However, they believed that the unique capacity of the Transportation Center to bring together leaders from industry and government, as well as leading scholars from economics, law, engineering, psychology and sociology who have done research on the problems associated with the transportation of hazardous materials and wastes (hazmats), could produce a set of integrated insights and understandings that would go well beyond those of previous conferences. The papers that make up this volume were all delivered at Hazmat Transport '91. From a legislative point of view, they tend to deal with issues associated with the Hazardous Materials Transportation Act of 1975 (HMTA), the original act passed to regulate the transportation of hazardous materials, and the Hazardous Materials Transportation Uniform Safety Act of 1990 (HMTVSA). There were talks and papers presented at the conference that focused on other recent legislation and transportation issues with which HMTUSA does not deal. The conference proceedings volume also had discussions and papers on significant managerial and regulatory issues that could not be included in this volume because of constraints on its size. Therefore, this essay is made up of three parts.
