Welcome to IATBR

The International Association for Travel Behaviour Research (IATBR) is an international organization of scholars, researchers, practitioners, consultants, and public agency professionals dedicated to the advancement of travel behaviour research.  The organization aims to serve as a forum that brings together professionals from a wide range of disciplines interested in the study of the factors that influence activity and travel choices of people and businesses, the formulation of new computational and analytical modeling methods and approaches for forecasting activity-travel demand, and the analysis of the land use and transportation impacts of a wide range of socio-economic, public policy, and modal scenarios.  The association was established in the early 1970’s to facilitate the exchange of information among researchers around the world with a governing Executive Board reflecting the international balance of interests in travel behaviour research.

The main activity of the association has been the organisation of triennial conferences on travel behaviour research.  Papers presented at the IATBR conferences are published in a series of Elsevier/Emerald books and in special issues of various journals.  The Association meets annually in January at the Transportation Research Board Meeting in Washington, D.C. and occasionally at the European Transport Conference in Europe.  In addition, IATBR supports presentation sessions at other international transportation conferences and organises or co-sponsors smaller specialty conferences and workshops.

Please browse through this website to learn more about the activities of the organisation and consider supporting the Association through your membership and participation.

Professor Hani Mahmassani had a deep and lasting impact on the IATBR, and the broader transportation research community. The IATBR board has decided to organise two events to celebrate Hani’s life and contribution to the IATBR community. The first one will be an online event during the Bridging Transport Research Conference (BTR), and the second one will be a longer in-person event during the 18th IATBR Conference in Sydney in Dec 2027.

Prof Meead Saberi, former student of Prof Hani Mahmassani, is collating memories, messages, photos, and videos for inclusion in tributes and memorials for Hani, including the upcoming IATBR events. Please upload your contributions using this link, preferably by 3 Aug 2025.
