Public transportation in the U.S. facilitates mobility by providing transit service to the general public, especially for those without access to a personal vehicle. As a result, transit agencies can perform access evaluations using transit equity and coverage analysis to understand how their route choices affect transit services for different populations. Meanwhile, swift changes to public transit could occur if agencies elect to integrate autonomous technology like shared autonomous vehicles and electric, autonomous shuttles in their system. This study explored (1) an approach to identifying unmet service need based on transit dependence and low income and minority status and (2) a cost-based analysis of the feasibility of operating shared autonomous vehicles (SAVs) and autonomous shuttles as a part of a public transit system. The approach was applied to the Port Authority of Allegheny County system that serves southwestern Pennsylvania. This study found that it is feasible to implement SAVs and shuttles at an average of 83% and 58%, respectively, lower cost per mile than buses. The lower cost and ease of implementation lowers the barrier for agencies, ultimately improving transit coverage for those who need it the greatest.
