Transportation equity focuses on ensuring that all members of society have equal access to transportation options, regardless of their income level, race, age, or physical abilities. This research area seeks to address disparities in transportation access and availability, as well as the social, economic, and environmental impacts of transportation policies and infrastructure on marginalized communities. Transportation equity research often involves examining transportation systems, policies, and planning practices to identify and address barriers to access and mobility for disadvantaged groups, and to promote more inclusive and sustainable transportation solutions. This research area is important for promoting social justice, improving quality of life, and reducing inequities in society.
