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.

TRB produces and distributes about 200 publications annually. Most of the printed publications are also available electronically. The following are the major publications series:

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

In addition, TRB issues a variety of other publications, ranging from the Highway Capacity Manual to general-interest periodicals. TR News, a bimonthly magazine with an international circulation of 10,000, features timely articles on innovative and state-of-the-art research and practice in all modes of transportation.
