This report, prepared by the Transportation Research Board's Research and Technology Coordinating Committee, examines the federal role in the nation's overall highway research and technology (R&T) effort. Its emphasis is on determining whether the focus and activities of the federal program are appropriate in light of the needs of the highway system and its stakeholders as well as the roles and activities of other national highway R&T programs. The report is presented in five chapters. Chapter 1 provides an introduction. Chapter 2 presents information about the key public and private components of the highway industry, describes the barriers to innovation in highway transportation, reviews the drivers of the need for such innovation, and identifies major highway system issues that can be addressed by R&T. Chapter 3 provides an overview of key highway R&T programs, their current funding levels, and their research focus. Included is a comparison of highway R&T funding with R&T funding in other federal agencies and selected sectors of the economy. Chapter 4 presents the key characteristics of an effective federal highway R&T program and an assessment of the Federal Highway Administration program in light of these characteristics. On the basis of this assessment, Chapter 5 offers recommendations for improving and strengthening the federal highway R&T program. |
