TRB Special Report 244 - Highway Research: Current Programs and Future Directions describes the United States' highway industry and the major highway research and technology (R&T) programs. It then introduces a new framework for classifying highway R&T activities, maps the 1993 expenditures of the major public-sector programs on this framework, and presents suggestions and recommendations for the highway R&T program that reflect the Transportation Research Board's Research and Technology Coordinating Committee's vision of the needs of the highway transportation system for the next century.
