This report analyzes approaches taken by state departments of transportation (DOTs), their local partners, and other project sponsors to satisfy National Environmental Policy Act (NEPA) requirements for transportation projects involving more than one mode. Specific objectives of the research were to: 1) characterize the challenges inherent in satisfying the NEPA requirements of multiple U.S. DOT agencies; 2) identify strategies and tactics that state and local transportation agencies have used to overcome these challenges; and 3) suggest new and innovative strategies that can be applied by state and local transportation agencies in future multimodal NEPA processes. Twelve case studies illustrate successful practices and provide examples of institutional arrangements used to comply with NEPA requirements for two or more U.S. DOT agencies. The case studies demonstrated that there is no single best way to approach the NEPA process for multimodal situations. Success may depend more on the willingness and motivation of the agencies to work together, to find common ground, and to work around differing processes, and less upon a specific organizational structure. An effective interagency approach depends on how well the project sponsor and other agencies are able to work together and bridge their procedural differences.

Mobility is fundamental to economic and social activities, including commuting, manufacturing, or supplying energy. This book focuses on understanding how mobility is linked with geography. It links spatial constraints and attributes with the origin, destination, extent, nature and purpose of movements.

The fiscal year 1991 U.S. DOT Appropriations Act directed the Secretary of Transportation to conduct a National Bicycling and Walking Study. The five objectives of the study as specified in the Act were to: (1) Determine the current levels of bicycling and walking and identify reasons they are not better used as means of transportation; (2) Develop a plan for the increased use and enhanced safety of these modes and identify the resources necessary to implement and achieve this plan; (3) Determine the full costs and benefits of promoting bicycling and walking in urban and suburban areas; (4) Review and evaluate the success of promotion programs around the world to determine their applicability to the role required of the U.S. DOT to implement a successful program; and (5) Develop an action plan, including timetable and budget, for implementation of such Federal transportation policy. The purpose of this Interim Report is to document progress in addressing these five objectives. In dealing with each objective, this report summarizes available information, discusses what additional information is required, and outlines the approach to be used in collecting it.
