AAG Transportation Geography Specialty Group
The mission of the Transportation Geography Specialty Group of the American Association of Geographers is to encourage and facilitate interactions among individuals who are interested in research, practice, and education of transportation-related topics.
All members of the AAG with an interest in transportation and transportation-related issues are encouraged to join the Transportation Geography Specialty Group. Annual dues are $10 for regular members ($2 for student members) in addition to the normal AAG dues. Information and forms are available on the AAG home page and the AAG Knowledge Community.
TGSG at AAG 2026
2026 TGSG Award Winners
Award recipients will be recognized during the TGSG Business Meeting at the AAG Annual Meeting (March 19, 2026, 11:40 AM–12:40 PM PT, Nob Hill 2 and 3, Hilton, Tower 3). We invite TGSG members and the broader community to join us in congratulating the winners for their achievements and excellent contributions to the field.
- Edward L. Ullman Award: Ronald Buliung, University of Toronto Mississauga. Ronald Buliung is Full Professor at the University of Toronto Mississauga and currently serves as Vice-Dean, Graduate Studies and Postdoctoral Affairs. The TGSG Board selected Dr. Buliung for the Ullman Award in recognition of a distinguished body of scholarship that has advanced transport geography's understanding of travel behavior, mobility inequality, and the social organization of everyday transportation. A central reason for the Board's decision is Dr. Buliung's sustained intellectual leadership in research areas that have been under-recognized relative to their importance, especially geographies of disability and ableism and the mobility experiences of children and families. The Board noted the significance of Dr. Buliung's evolution from foundational travel behavior research to a focused and impactful agenda on parents and people with disabilities, drawing on both quantitative and qualitative approaches. This work has helped reframe mobility as a socially embedded and equity-critical phenomenon, and it speaks directly to the urgent need to improve everyday accessibility for people with disabilities. In addition to scholarly contributions, the Board also recognized Dr. Buliung's long-standing service to the community, including past leadership as Vice Chair of TGSG and sustained engagement with AAG and the field's core journals, as well as a strong record of mentorship and graduate training.

The Journal of Transport Geography
The Journal of Transport Geography is a leading interdisciplinary journal focusing on the geographical dimensions of transport, travel and mobility. It is international in its outlook, and welcomes both conceptual papers and theoretically-informed, empirically-oriented contributions on the movement of people, goods and/or information by any mode and at every geographical scale.
Articles and viewpoints for the Journal of Transport Geography may be submitted through the Elsevier Website.
