Accessing global transport knowledge

ITRD remains as an entity to coordinate the ITRD member input to the TRID database.

These webpages provide quick, practical information on how to become an ITRD Member.

ITRD (International Transport Research Documentation) forms a multilingual database which is part of the TRID database and delivers high quality information on global developments in transport and transport research. Your institution's research material can be made widely available by joining ITRD.

ITRD contains information on transport and transportation research, designed to meet the needs of engineers, consultants, documentation centres and researchers worldwide. Overlap and replication can be avoided and new ideas and technologies made accessible on a timely basis through the sharing of research and experience made possible by ITRD.

Geographical Coverage

The ITRD database reflects the transport research literature of more than 20 countries including most European countries, Australasia, Latin America, Canada, China and Japan. It also includes abstracts of transport literature published by other organisations/associations such as the OECD / ITF Transport Research Centre and, for example, the World Road Association (PIARC).

More than 3 000 references are added each year. A unique aspect of ITRD is its use of four official languages in the database; English, French, German and Spanish, and each record is available in one of these languages.
