Over the last decade, there has been increasing interest among geographers in a critical perspective on studies of transportation and mobility, or studies that take into account the power relations within systems of transportation that produce space, place, mobility, and/or identity. This ever‐growing body of work includes people who might not consider themselves as transportation geographers per se, but nevertheless are expanding geographies of transportation beyond the traditional focus on vehicles, infrastructure, and economics. In this article, we review such work from three different perspectives: critical studies of professional practice, the interdisciplinary approach of Caribbean Studies, and the work of activists and scholar‐activists to connect environmental justice with mobility justice.
