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.
