TRB's Synthesis of Information Related to Highway Problems searches out and synthesizes useful knowledge from all available sources and prepares concise, documented reports on specific topics. Reports from this endeavor constitute an National Cooperative Highway Research Program (NCHRP) report series, Synthesis of Highway Practice.

TCRP is an applied, contract research program that develops near-term, practical solutions to problems facing transit agencies.

TRB's Cooperative Research Programs Division manages several cooperative research programs that frequently produces reports that have relevence to issues outside of the program's core focus areas.

TRB's Technical Activities Division provides a forum for transportation professionals in all modes and functions to identify research needs and to share information on research and issues of interest. The Division's staff of specialists in each mode and discipline work with a network of volunteers to carry out activities on behalf of TRB sponsors and the transportation community, including the TRB Annual Meeting, conferences and workshops, publications, visits to each state, and responses to inquiries. This network includes members and friends of over 200 standing committees, supplemented by designated TRB representatives in each state, over 150 universities, and 35 transit agencies.

Congress established the SHRP 2 in 2006 to find strategic solutions to three national transportation challenges: improving highway safety, reducing congestion, and improving methods for renewing roads and bridges. Research was focused in four areas, which are described below. The program carried out 145 research projects and produced 130 products as well as 132 research reports.

TRB's Research in Progress (RiP) Database now contains more than 11,900 current or recently completed transportation research projects. Most of the RiP records are projects funded by federal and state departments of transportation. University transportation research is also included. The RiP Database also serves as a clearinghouse of University Transportation Centers ongoing research.

An important function of TRB is to stimulate research that addresses concerns, issues, or problems facing the transportation community. In support of this function, TRB Technical Activities standing committees identify, develop, and disseminate research need statements (RNS) for use by practitioners, researchers, and others.

TRB's TRID is integrated database that combines the records from TRB's Transportation Research Information Services (TRIS) Database and the OECD's Joint Transport Research Centre’s International Transport Research Documentation (ITRD) Database. TRID provides access to over 900,000 records of transportation research worldwide.
