요약Sustainability has emerged as a central paradigm in the evolution of transportation systems. The transportation sector is a major contributor to local air pollutants, greenhouse gas (GHG) emissions, and urban congestion. In response, policymakers and urban planners have increasingly prioritized strategies that promote multimodal integration, accelerate vehicle electrification, and expand access to shared mobility services. Nonetheless, more limited attention has been given to the interactions among these systems and the conditions under which their adoption and integration can be most effectively supported.In this dissertation, I aim to address this limitation through two empirical applications to shared mobility that offer a demand-side perspective and a supply-side lens. While shared micromobility and ridehailing electrification have been studies independently, few works empirically evaluate their interaction with public transit at the system level, or rigorously assess the economic and behavioral barriers to electric vehicle adoption among ridehailing drivers using cost modeling and original data (e.g., survey) collection. In response to these gaps, on the demand side, I focus on the active transportation mode (shared micromobility users); on the supply side, my research centers on transportation network companies (TNCs) service providers of the ridehailing industry.Research ObjectivesIn response to some notable knowledge gaps, my dissertation pursues four core research objectives, to: 1) examine how shared micromobility systems can become more integrated versus isolated, 2) evaluate the financial considerations involved in adopting electric vehicles (EVs) in ridehailing fleets, 3) identify the factors shaping perceptions and adoption potential of EVs among ridehailing drivers, and 4) assess how policy interventions might facilitate the uptake of sustainable shared mobility options on both the active (bikesharing and scooter sharing, demand side) and automotive (ridehailing, supply side) sides of the spectrum.BackgroundShared micromobility such as bikes and scooters refers to the shared use of small, low-speed vehicles, often powered by human effort or electricity. Its popularity has grown in recent decades due to its flexibility and energy efficiency, particularly for short-distance trips and first- and last-mile travel. In contrast, fixed-route rail (i.e., not including buses) transit enables faster and longer-distance travel, but its fixed routes limit door-to-door convenience. When combined, shared micromobility can complement or substitute parts of a rail trip, particularly for first- and last-mile connections. This integration enhances not only access to transit but also overall travel speed and reach. My dissertation explores this integration from the user's perspective to better understand how sustainable modes can work together.In addition, ridehailing services like Uber and Lyft have become major players in urban transport since the 2010s. However, these services have also contributed to increased vehicle miles traveled (VMT), congestion, and emissions. In response, California passed Senate Bill (SB) 1014 (Clean Miles Standard) in 2018, requiring the California Public Utilities Commission (CPUC) and the California Air Resources Board (CARB) to set annual GHG reduction targets for ridehailing fleets by encouraging EV adoption. While this policy is a step toward lowering transportation emissions, important challenges remain, such as EV charging access, the affordability of EVs, and how policies might apply to full- and part-time drivers.Guided by these motivations, my dissertation investigates the adoption of sustainable mobility strategies and evaluates related policy options, with a focus on two areas: 1) the integration of shared micromobility with rail public transit and 2) the electrification of ridehailing services.MethodsMy work offers a broad understanding of sustainability efforts in shared mobility system integration, user- and provider-focused behavioral dynamics, and future policy considerations. This dissertation starts with an introduction in Chapter 1, presenting an overview of transportation sustainability and shared mobility. It also highlights the gaps identified in existing research and applications of micromobility and ridehailing.Chapter 2, What Is the Connection? Understanding Shared Micromobility Links to Rail Public Transit Systems in Major California Cities, introduces the first of three studies that collectively advance the goals of this dissertation. I investigate the integration of shared micromobility and public transit systems by analyzing spatial-temporal usage patterns of bikesharing and scooter sharing around rail public transit hubs in four California cities (San Francisco, Los Angeles, Sacramento, and San Jose). This analysis evaluates over one million shared micromobility trips and real-time transit schedule data from October 2019 to February 2020. It identifies the contextual factors that influence whether shared micromobility serves as a complement or substitute to fixed-route transit services. To measure the spatial proximity of trips linked by the two systems, I employed an automated data pipeline to extract OpenStreetMap (OSM) road networks and computed network travel distances between shared micromobility trip origins and destinations. I further incorporated the General Transit Feeds Specification (GTFS or transit schedules) to exclude trips occurring outside. (Abstract shortened by ProQuest).
