	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
