Public transit in the U.S. is characterized by low quality and ridership compared to its global counterparts. This paper aims to understand the provision of public transit in U.S. cities and whether the current fare structure can be redesigned to improve efficiency and equity. I develop a structural model of transit service demand and supply, with the demand side capturing commuters’ travel mode choices and the supply side characterizing the decisions of transit managers regarding fare and service quality. Using a novel data set created from a fine level national household travel survey combined with data from Google Maps along with transit operation data, I estimate the model to recover urban commuter preferences on travel times, cost structure for supplying transit services, while taking into account transit manager’s political or distributional preferences. The estimated parameters suggest that transit agencies, under financial constraints, prioritize lower-income and nonWhite populations in their decisions. Counterfactual simulations show that means-tested pricing could more effectively address equity concerns without compromising efficiency gains. Furthermore, even in the absence of explicit means-testing, pricing models such as cross-modal subsidization and zonebased transit fares can achieve comparable distributional objectives, though these schemes differ in their specific distributional and welfare properties.
