Management and operation of emerging mobility services

Mobility services, such as ridesourcing and e-scooters, are changing the transportation landscape. These services are often unregulated and their impact on traffic or alternative modes is not well understood. In this dissertation, we study two features of mobility services: (1) we analyze the management of ridesourcing platforms through policies aimed at minimizing their congestion externality; in particular, we investigate policies that reduce idling drivers and improve operational efficiency, (2) we explore the interaction between mobility services and alternative modes; in this case, we study the relationship between e-scooter ridership and transit. While the first part of the dissertation develops mathematical models to understand time-dependent policies for ridesourcing management, the second component focuses on statistical and equity analysis of observed e-scooters data in Austin, TX.Civil, Architectural, and Environmental Engineerin
