**Description:**
        This tool houses published or ongoing research projects covering all aspects of transportation, including data collection and analysis. This tool is the world’s largest and most comprehensive bibliographic source on transportation. It contains more than one million records of published and ongoing research. Users can navigate several databases, searching by key-words or research authors. The online database consists of six components:

Transport Research International Documentation (TRID): An integrated database that combines the records from TRIS and the Organization for Economic Cooperation and Development’s (OECD) Joint Transportation Research Center’s International Transportation Research Documentation database. It is the largest and most comprehensive bibliographic source on transportation information.
	Research in Progress Database: It contains current or recently completed transportation research projects, mostly those funded by US Department of Transportation (DOT), state DOT, or the Transportation Research Board’s (TRB) cooperative research programs.
	Research Needs Statement Database: It houses research need statements that are identified, developed and disseminated by TRB Technical Activities standing committees.
	TRB Publications Index: It contains papers, articles, and reports published by TRB, Highway Research Board, Strategic Highway Research Program, or the Marine Board from 1923 to date.
	Practice Ready Papers Database: It contains practice-ready papers in which the research results presented and discussed make a contribution to the solution of current or future problems.
	TRB Library: The library provides reference service, citation verification, literature searches and interlibrary loan services to TRB staff and sponsors.
