Transportation Research Board

As part of the National Academies of Sciences, Engineering, and Medicine, the Transportation Research Board (TRB) mobilizes expertise, experience, and knowledge to anticipate and solve complex transportation-related challenges. The Board’s varied activities annually engage more than 5,500 engineers, scientists, and other transportation researchers and practitioners from the public and private sectors and academia, all of whom contribute their expertise in the public interest. The program is supported by state departments of transportation, federal agencies including component administrations of the U.S. Department of Transportation, and other organizations and individuals interested in the development of transportation. The Transportation Research Board (TRB) is one of four centers within the National Academies of Sciences, Engineering, and Medicine. Through research, convening, and information exchange, TRB helps transportation professionals, policymakers, and researchers anticipate emerging challenges and opportunities across all modes of transportation. With more than a century of experience, TRB continues to connect research, practice, and policy to create a safer, more efficient, and affordable transportation future.
