In 2011, TRB and ITRD released TRID, the TRIS and ITRD Database. TRID is the world's largest and most comprehensive bibliographic resource on transportation research information. It is produced and maintained by the Transportation Research Board of the US National Academies with sponsorship by State Departments of Transportation, the various administrations at the U.S. Department of Transportation, and other sponsors of TRB's core technical activities. ITRD is produced by ITRD member organizations under the under the sponsorship of Joint Transport Research Centre (collectively JTRC) of the International Transport Forum and Organisation for Economic Cooperation and Development (OECD) and ITRD.
The TRID Database contains more than 900,000 records of references to books, technical reports, conference proceedings, and journal articles in the field of transportation research. Almost 500 serial titles are regularly scanned and indexed for TRID. TRID's focus is transportation research. TRID does not contain information on vehicle standards and specifications, patent information, market research, or military transport.
TLIB Records are bibliographic records received from major transportation libraries. These citations generally do not have abstracts but they cover journals and publications that would not otherwise be covered in TRID. The Harmer E. Davis Library at the Institute of Transportation Studies at the University of California, Berkeley provides monthly updates of journal articles and technical reports. The Northwestern University Transportation Library provides monthly contributions of selections from its TRANWeb database (a database of journal articles and papers on transportation and law enforcement).
Almost 20,000 Environmental Impact Statements from the EIS Database produced by the Northwestern University Transportation Library have been added to the TRIS Database to date. TRID now contains records for the largest collection of Environmental Impact Statements in the world.
Since 2007, the Northwestern University Transportation Library has contributed transportation-related theses to the TRID database. To date approximate 3,000 records have been contributed. The Northwestern University Transportation Library adds new thesis records to TRID annually.
