About TRID
In 2011, the Transportation Research Board and ITRD released TRID, the TRIS and ITRD Database. TRID (Transport Research International Documentation) 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 U.S. National Academies of Sciences, Engineering, and Medicine with sponsorship by state departments of transportation, the Federal Highway Administration (FHWA) and various federal agencies, 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.
TRID covers all modes and disciplines of transportation and contains more than 1.5 million records of published research. More than 495,000 records contain links to full-text documents.
Records in TRID are indexed with a standardized vocabulary from the Transportation Research Thesaurus (TRT), ITRD Thesaurus or a different thesaurus depending on the source organization.
Researchers can submit a published transportation report or document online for indexing in TRID or email it to tris-trb@nas.edu.
Short videos, webinars and fact sheets on searching TRID are available here.
TRID Coverage
The TRID Database contains more than 1.5 million records of references to books, technical reports, conference proceedings, and journal articles in the field of transportation research. More than 600 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.
In addition to the material that is indexed and abstracted at the TRB and from ITRD, TRID receives records from several sources:
J-STAGE
TRB and the Japan Science and Technology Agency (JST) signed a Memorandum of Understanding (MOU) to share records of transportation related research from JST’s J-STAGE Database with TRB’s TRID Database. The J-STAGE Database is Japan's largest electronic journal platform for academic societies. It disseminates research in the form of peer-reviewed articles from 1,500 journals published by academic societies in Japan. All J-STAGE records added to TRID will include English language abstracts. Approximately 80% of the records in J-STAGE have full text articles available free of charge. Many of the articles in J-STAGE are available in English. The inclusion of J-Stage records in TRID provides increased access to important Japanese transportation research and greatly increases the international coverage of TRID.
This MOU between TRB and JST is an outcome of the International Transportation Research Information Access Workshop held in 2012.
ATRI
The Australian Transport Index (ATRI) is a curated bibliographic database developed by the MG Lay Library at the National Transport Research Organisation (NTRO), formerly ARRB. It supports the transport research community in Australia, New Zealand, and internationally by indexing land transport research, with a strong emphasis on Australian and New Zealand publications. Developed over 50 years, ATRI contains more than 200,000 records, including scholarly literature and grey literature such as government reports, technical guidelines, and conference papers.
