Inequalities in public transportation systems have been of significant consideration to transport researchers and urban planners for several decades. Understanding the complexities within transit systems is crucial for achieving mobility justice and providing mobility options to transit-dependent individuals. However, the majority of research on transit inequality analyses disparities using measures such as coverage or efficiency. Meanwhile, studies that consider transit inequality in the context of urban dynamics tend to use naive approximations to represent transportation systems. In this talk, we combine detailed transit modelling, amenity visitations data, and census surveys to explore how transit systems in the United States fit into the larger context of various mobility demands. Specifically, we highlight transit disparities in relation to residential-workplace dependencies, experienced segregation, and the built environment.
