High Speed Rail in America: Promise and Peril - Ten Years Later

This panel discussion was held on 25 February 2022 at the virtual Association of American Geographers Annual Meeting and sponsored by the Transport Geography Specialty Group. This session was a ten-years-later followup to a panel discussion held on 26 February 2012 at the AAG Annual Meeting in NYC. This panel discussion covered perspectives on lessons learned over the past decade, and how those lessons could inform policy and planning in the momentous energy, mobility, environmental, and political transformations that were expected over the next decade.

TGSG Board Statement of Solidarity

22 June 2020

The Transportation Geography Specialty Group expresses their solidarity with the American Association of Geographers and the specialty groups of the AAG, the Black Lives Matter movement, and all of our friends and colleagues of any color, race, gender, or decree in speaking out, protesting, and working to change the endemic racism, injustice, and inequality that permeates society. We are deeply saddened by the murders of George Floyd, Breonna Taylor, Ahmaud Arbery, and Rayshard Brooks as the latest in a long history of violence, discrimination, and brutality along racial, gender, and other lines. These actions are unacceptable in a country that promotes itself as the land of the free and the home of the brave.

Transportation is a unique field of study in that it is deeply embedded in the fabric of all individuals of our species. We all must utilize and rely on it to function and participate in society. Transportation as an industry and a discipline has had a dialectical role in American race relations, both facilitating injustice and contributing to social change. Some examples include the Great Migration that was facilitated by railroads, which were built by suppressed immigrant labor. Discrimination in busing let to Rosa Parks and the Freedom Riders. The Pullman Porters were underpaid, overworked, and disrespected, but these were also jobs that African-Americans desired, and became a catalyst for the development of labor leaders who were later pivotal in the Civil Rights movement.

Our mobility systems today continue to facilitate inequities that divide our society. For example, automobile ownership and use as a requirement for participation in society places disproportionate burdens on lower-income households, which themselves are disproportionately people of color and underrepresented minorities. Efforts to increase active transportation and walkable communities facilitate sustainable mobility, but also place uneven burdens on people of color, including heightened police attention and reduced consideration from motorists. Contemporary work in transit and transportation provides stable, middle-class employment, but these "essential" jobs have proved especially deadly during the COVID-19 pandemic, and exposed the increased vulnerability to already disadvantaged populations.

Transportation has made significant progress in recent decades in diversifying its ranks and in progressing research and teaching on mobility inequities. Work in topics such as sustainability, spatial mismatch, modal choice, and accessibility to name a few have contributed to this progress. But, as is evident with a casual glance at almost any street, much work remains to be done.

This gives our work a special level of responsibility to equality and justice.

We commit to be a more inclusive specialty group, to encourage the participation of members of historically underrepresented peoples in transportation in our conferences, in our collaboration, and in our research and teaching. We commit to project, without fail, an open, supportive, and constructive environment for all who are interested in our fascinating and dynamic field. We commit to ask better questions, to be better listeners, and to learn. We commit to do better.

To these ends, we also ask for your suggestions and input for how to best proceed going forward to building a most equitable and just research group, and to making our contribution to building the just, fair, and sustainable world we all deserve to share in together.

Yours sincerely,

The Leadership of the Transportation Geography Specialty Group

2020 AAG Virtual Annual Meeting

The in-person 2020 Annual Meeting was cancelled due to the COVID-19 pandemic, but organizers assembled 175+ sessions, meetings, and events for the virtual meeting, including four sessions co-sponsored by the TGSG. Video of those sessions will be available for a limited time on the AAG Annual Meeting website:

The cancellation of the in-person conference forced the cancellation of 37 sessions sponsored by the TGSG, including the 2020 Fleming Lecture, which was to be given by last year's Ullman Award winner, John-Paul Rodrigue. Plans for Dr. Rodrigue's address as well as the Fleming Lecture for 2020 Ullman Award winner, Julie Cidell, will be announced prior to the 2021 AAG Annual Meeting in Seattle.

2017 AAG Annual Meeting: Boston, MA

The Transportation Geography Specialty Group sponsored or co-sponsored 25 sessions at the American Association of Geographers Annual Meeting in Boston, MA, April 5 - April 9, 2017. The group's business meeting was held on April 7, 2017.

The 2017 Edward L. Ullman Award for contributions to the field of Transportation Geography was given to Dr.Isabelle Thomas, Professor of Geography at Universite Catholique de Louvain in Louvain-la-Neuve, Belgium. Over the span of the past 30 years, Dr. Thomas has authored or co-authored over 150 publications, accruing nearly 4000 citations. Her major contributions can be found in a number of sub-disciplines of transportation and urban geography. She was a leading pioneer in the use of fractals to classify and understand urban growth patterns and the spatial structure of built-up urban areas, including transportation networks. She has also been a prominent researcher on road accident analysis both automotive and bicycling crashes leading to work on determinants of cycling and policies for promoting non-motorized transportation. Other noteworthy research touches on aspects of accessibility, commuting, and transportation-land-use modeling. In addition to research, Dr. Thomas has been an active participant in the NECTAR series and has served or is serving on the editorial board of a number of journals.

Edward L. Ullman Award

The Edward L. Ullman Award has been offered by the Transportation Geography Specialty Group of the Association of American Geographers since 1990 for outstanding contributions to the field of transportation geography. Edward Louis Ullman (1912 – 1976) was a highly influential transportation geographer and spent most of his academic career at the University of Washington.

The Fleming Lecture in Transportation Geography

When in 1992 Professor Douglas Fleming retired from his teaching career in transportation at the University of Washington (and his earlier career in merchant shipping), the Department of Geography decided to create a fund that would enable to offer an honorarium for a distinguished lecture at the Annual Meetings of the Association of American Geographers. This lectureship, which honors the long tradition of transportation studies at Washington, including William Garrison and Edward Ullman, as well as Doug Fleming, is designed to recognize outstanding contributions in the field. Since the Transportation Geography Specialty Group includes most of the academic specialists as well as many people in the transportation sectors of the economy, the department at Washington solicits the recommendation each year of an outstanding person to honor. Past speakers include:

Dissertation and Thesis Award Winners

The TGSG Outstanding Thesis and Dissertation Awards recognize outstanding theses and dissertations in transportation geography. There are two awards, one for best Master's thesis and one for best PhD dissertation. These awards each have a $300 prize, and winners are recognized and receive a plaque at the awards luncheon. We encourage submissions by students who do not necessarily consider themselves transportation geographers but are working on exciting and innovative transportation topics. Students must be members of the AAG to be eligible for either award.
