The Role of Public Transportation and Mobility Management in an Era of New and Expanding Shared Mobility Options

Project Scope:

The study committee will consider the role of new and expanding shared mobility options, such as ridehailing, taxis, carsharing, bikesharing, scootersharing, and microtransit, in the provision of transportation services as part of regional transportation systems, and specifically the relationship to and impact of these services on existing public transit. As part of the study, the committee will consider: 1) how these services can improve the transportation system’s ability to further goals such as accessibility, efficiency, equity, sustainability, and safety; 2) the role transit agencies and other entities could play in managing and otherwise furthering the new mobility landscape; and 3) ways that transit agencies have coordinated with the new mobility providers both in the United States and abroad.
