National Cooperative Highway Research Program

NCHRP announces its FY 2015 projects; requests for proposals are expected to be released starting in August 2014.

The NCHRP Synthesis program is seeking consultants for FY 2014 Synthesis topics. Please note that the deadline for receipt of consultant letters of interest is close of business, Friday, August 15, 2014.

NCHRP's 2013 Summary of Progress highlights the more than 161 projects completed in 2013 and includes a listing of the more than 2,800 other projects undertaken by the program since 1962. The Summary of Progress also presents detailed information about the operation of NCHRP through the Standing Committee on Research of the American Association of State Highway and Transportation Officials.

Information on all projects initiated under the NCHRP from its inception in 1962 through 1988 is included in NCHRP Web Document 7: Special Edition of Summary of Progress through 1988.

Unfunded CRP problem statements will be posted periodically as each program's fiscal year project selection is made.

• Reports: Reports are the main product of the research project and are often written as guidebooks or manuals.
• Syntheses of Practice: Syntheses report on the state of the practice based on literature reviews and surveys of recent activities about innovations being used by others to solve problems.
• Research Results Digests (RRDs): RRDs are used to promote early awareness of project results in order to encourage implementation.
• Legal Digests (LRDs): LRDs report on timely legal issues, compile case law, or recommend specific solutions to specific problems.
• Web-Only Documents: Web-only documents are fully searchable PDFs of contractor-prepared reports or supporting appendix materials.
• Selected Studies in Transportation Law: The SSTL series is jointly published by the National Cooperative Highway Research Program (NCHRP) and the Transit Cooperative Research Program (TCRP).
