TheTransportation Research Board (TRB) is a division of theNational Academies of Sciences, Engineering, and Medicine. TRB's mission is to mobilize expertise, experience, and knowledge to anticipate and solve complex transportation-related challenges. For example, committees, researchers, and staff are currently[when?] focused on advancing resilient infrastructure, exploring transformational technology, and caring for the public’s health and safety. It publishes research via four cooperative research programs and through consensus studies, which may be requested by the U.S. Congress.
As one of seven major divisions of the National Academies of Sciences, Engineering, and Medicine,[1] TRB research is objective andinterdisciplinary. TRB hosts nearly 200 standing technical committees that address specific aspects of transport and the TRB Annual Meeting attracts thousands of transportation professionals.
The Transportation Research Board was established in 1920 as the "National Advisory Board on Highway Research" and changed its name to the "Highway Research Board" from 1925 until 1974, when it was renamed again as the "Transportation Research Board." It has commissioned ad-hoc research since 1950, became more involved in multi-modal transport in the 1960s, and continues to research across various transportation modes.[1]
TRB's varied activities annually draw on over 8,000 engineers, planners, scientists, academics, and other transportation researchers from the public and private sectors, who volunteer expertise in the public interest by participating on TRB committees, panels, and task forces.[1]
Additionally, TRB hosts its Annual Meeting in Washington DC every January, gathering approximately 14,000 transportation professionals from across the United States and around the world.[2]
At the 2025 TRB Annual Meeting,Nuria Fernandez was presented with the Frank Turner Medal for Lifetime Achievement in Transportation.[3]
Publications include theHighway Capacity Manual, theTransportation Research Record: Journal of the Transportation Research Board (TRR) which publishes peer-reviewed papers,[4] and a bi-monthly magazine calledTR News. A history of transportation research and of TRB was published in January 2020 calledThe Transportation Research Board, 1920–2020: Everyone Interested Is Invited.[5]
Transportation Research Information Services (TRIS) offers several databases for researchers:
Although many activities are requested and funded by Congress and federal agencies, TRB and the National Academies do not receive direct appropriations from the federal government. Programs receive support from statetransportation departments, the various administrations of theU.S. Department of Transportation and other federal agencies, industry associations, and other organizations and individuals interested in the development of transportation.
The Cooperative Research Programs receive funding. The Behavioral Traffic Safety Cooperative Research Program (BTSCRP) facilitates projects with support from theGovernors Highway Safety Association.[11] The Airport Cooperative Research Program (ACRP) is sponsored by theFederal Aviation Administration.[12] The National Cooperative Highway Research Program (NCHRP), created in 1962, is sponsored by individual state departments of transportation of theAmerican Association of State Highway and Transportation Officials and theFederal Highway Administration.[13] The Transit Cooperative Research Program (TCRP) is sponsored by theFederal Transit Administration and carried out under a three-way agreement among theNational Academy of Sciences, the Transit Development Corporation, Inc., and theAmerican Public Transportation Association.[14]
TRB offers selective research funding, notably, the NCHRP, the ACRP, and TCRP. Each one of these programs has industry leaders who function as references while completing the project.[15]
