TRB Publications

To fulfill one of its oldest missions, TRB disseminates transportation research results and technology information through an extensive array of publications. These include books and reports assessing the state of the art or practice in specific areas of transportation, presenting the results of transportation research, addressing major national transportation policy issues, and identifying research needs. TRB books and reports span the range of transportation functions, disciplines, and modes. To search for publications produced by TRB since 1923, visit TRB's Publications Index website. To purchase a TRB publication, visit TRB's online bookstore. TRB publications can be browsed by series or by subject areas.

	Transportation Research Record (TRR) contains technical papers that have been accepted for publication through a rigorous peer-review process refereed by TRB technical committees.
