International Transport Research Documentation (ITRD)


International Transport Research Documentation has at its heart the IRTD database - a co-operative worldwide database of published information on transport and transport research.

ITRD is administered by the Joint Transport Research Centre of the OECD and the International Transport Forum.

ITRD contains over 350 000 bibliographical references and about 10 000 are added each year.

It reflects the transport research literature of 25 countries including most of the European countries, Australia, Latin America, Canada, China, and Japan. It also includes abstracts of transport literature published by other organisations/associations such as the US Transport Research Board (TRB), the OECD, the International Transport Forum, and the World Road Association (PIARC).

Each record contains an informative abstract in one of the four official ITRD languages : English, French, German, Spanish. The ITRD multilingual thesaurus allows searching by the term code which is the same whatever the language of abstract.


Input to the ITRD database is provided by ITRD members, which represent 30 renowned institutes.
