Transportation infrastructure and policy has an extensive history of social injustice. Today, such concerns also include environmental factors such as climate change that affect people in several regions and across the globe. There are also topics such as subsidies, disability services, land use regulations, distribution of services, urban sprawl, and zoning issues that require consideration for transportation decisions that are not immediately known. Despite having several issues that intersect with social justice, philosophers have, until recently, neglected to thoroughly study transportation. However, this trend is changing, and transportation justice, as an area of study within philosophy of the city, is gaining momentum. This chapter examines recent progress and some future directions that it could go, revealing different ways that philosophers of the city can contribute to how we understand and address issues in transportation justice.
