The International Transport Research Documentation (ITRD) is a bibliographic transport research database that contains more than 300 000 bibliographical references on transport research literature in OECD and non-OECD countries. Each record contains an informative abstract, from the world's published literature on transport (reports, books, journal articles, conference proceedings). About 10 000 references are added each year. There are 4 official languages represented in the database, English, French, German and Spanish, and each record is available in one of these languages.
Since January 2003, ITRD is administered by TRL on behalf of the OECD.
ITRD records encompass the following fields related to road and intermodal transport:
Traffic Transport Vehicles
Highway financing and administration
Transport economics and policy
Construction of pavements, bridges, and tunnels
Design of roads and related structures
Drainage of soils
Soils and rock mechanics.
ITRD also includes summaries of on-going research in participating countries via the Transport in Progress (TRIP) product.
Today, 26 research institutes from 19 of the 30 OECD Member countries participate in ITRD and contribute to the database. Four institutes from non-OECD countries are also active members of ITRD.
The ITRD database therefore reflects the transport research literature of 23 countries. It also includes abstracts of transport literature published by other organisations/associations such as the Transportation Research Board (TRB), the European Conference of Ministers of Transport (ECMT) and the World Road Association (PIARC).
ITRD Membership is open to OECD and non-OECD countries. The main benefits that have accrued to the transport research institutes that have joined ITRD include:
Possibility to disseminate their own organisation's published information worldwide;
Networking benefits with ITRD member organisations throughout the world;
Access to the participating countries' published and on-going research information.
Any transport research institute that would be interested in joining the ITRD scheme is welcome to contact the OECD/RTR Secretariat.
The following are regular ITRD customers:
National and local governments
Students and academics.
Current customers recognise that ITRD is a useful and powerful tool, which enables them to identify very efficiently the existing transport research literature on a given subject. This constitutes a substantial time gain compared to a scattered Internet search among transport research institutes and publishers around the world.
Users cite the following as being unique features of ITRD:
ITRD is evolving to best respond to the changing requirements of its members and users. Since 1999, the scope of the database has been expanded to also include inputs on transport economics, transport policy and intermodal transport.
The ITRD database is accessible to anyone (individual, companies, governments, research institutes) from any region via two main supports:
TRIP -- The Transport Research in Progress section of ITRD -- is also available on a standalone CD-ROM.
