TRID is a newly integrated database that combines the records from TRB's Transportation Research Information Services (TRIS) Database and the OECD's Joint Transport Research Centre's International Transport Research Documentation (ITRD) Database.
The TRID Database covers all modes and disciplines of transportation and 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. Over 64,000 records contain links to full-text documents.
TRID's focus is transportation research. TRID does not contain information on vehicle standards and specifications, patent information, market research, or military transport.
