TRIS Online is a public-domain, web-based version of the Transportation Research Information Services (TRIS) bibliographic database. TRB continues to produce and maintain the TRIS Database with funding by sponsors of TRB, primarily the State departments of transportation and selected federal transportation agencies. TRIS Online is the largest resource of published transportation research containing over 530,000 records of technical reports, journal articles, conference papers and monographs related related to modes and disciplines of transportation. Over 24,000 of the records in TRIS Online now provide links to the full text documents. The NTL publishes TRIS Online on its website. NTL's Digital Archive includes technical reports from the University Transportation Centers, State Departments of Transportation and other resources
