- 요약Access to reliable and affordable transportation shapes opportunities for employment, education, healthcare, and food. Yet for many urban residents, particularly those without access to a private vehicle, mobility remains a challenge. Public transit networks can fall short in terms of coverage, frequency, and flexibility. Carsharing has long been positioned as one strategy to address these gaps by offering short-term vehicle access without the costs and responsibilities of ownership. Since its early implementation in Zurich in 1948, carsharing has expanded globally and evolved into multiple service models, including roundtrip systems, where vehicles must be returned to their point of origin (e.g., Zipcar), and one-way systems, which allow for pickup and drop-off at different locations. Within the one-way model, some services are station-based, requiring users to pick up and return vehicles to designated stations (e.g., BlueLA), while others operate as free-floating systems that allow vehicles to be parked anywhere within a defined service area (e.g., Evie Carshare). These carsharing systems can offer flexibility and convenience, particularly in dense urban areas.However, the benefits of carsharing have not been equitably distributed. Research has shown that users tend to be younger, higher-income, and multimodal travelers, while cost, carsharing access, and digital barriers have historically limited adoption among lower-income households. In response to these disparities and energy and environmental concerns, electric vehicle (EV) carsharing has re-emerged in recent years. EV carsharing combines the flexibility of shared mobility with the climate benefits of electrification. While EVs have been included in carsharing programs since the 1990s, advances in battery technology, expanded charging infrastructure, and targeted policy incentives have accelerated their integration. EV carsharing promises to reduce urban air pollution and greenhouse gas (GHG) emissions, but it also introduces new challenges, including infrastructure requirements, operational constraints, and questions around long-term service viability.My dissertation focuses on one-way EV carsharing as a potential strategy for addressing both environmental and social equity goals. I investigate whether EV carsharing reduces energy consumption and associated GHG emissions, how different user groups engage with these services over time, and whether carsharing improves access to essential destinations such as grocery stores. These questions are especially relevant in underserved communities, where mobility barriers and transportation-related pollution are more pronounced.Research GapsMy research identifies the following gaps in the EV carsharing literature:1. Environmental Impact Measurement: Previous studies have extensively documented the environmental benefits of roundtrip and one-way carsharing; however, most of this work focuses on conventionally powered vehicles in higher-income, urban neighborhoods. The electrification of carsharing fleets has been recognized as a promising strategy for reducing emissions, yet studies evaluating EV carsharing's energy and environmental impacts in underserved communities remain limited. Additionally, prior assessments estimate emissions based on VMT reductions and fuel economy assumptions, rather than directly measuring electricity consumption and the emissions associated with EV charging.2. User Retention and Behavior Over Time: While previous studies have examined the sociodemographic profiles and tracked usage patterns and impacts such as VMT reduction and changes in vehicle ownership over time, there has been less focus on longer-term engagement and retention.3. Grocery Access: Although access to a private vehicle is one determinant of food access, few studies examine the relationship between carsharing and grocery store access. Research on food accessibility has typically relied on static proximity metrics, such as straight-line distances or fixed travel times, which are unlikely to capture the accessibility experienced under real-world conditions from both a spatial and temporal perspective.To address these gaps, my research is guided by the following five hypotheses:1. One-way EV carsharing reduces VMT and GHG emissions, with electrification further amplifying these effects.2. One-way EV carsharing user activity patterns, including trip frequency, duration, and travel distances, differ between general and low-income qualified members, with low-income users demonstrating higher frequency of use, longer trip durations, and greater travel distances.3. One-way EV carsharing membership type (i.e., general or reduced-cost for low-income qualified users) influences the duration of user active engagement and retention, with low-income users remaining active in the service for longer periods than general members.4. Spatial-temporal accessibility from one-way EV carsharing stations to different grocery store types varies based on store type, traffic conditions, and trip departure times.5. One-way EV carsharing users differ in their perceived grocery access and station usage patterns, with low-income users reporting greater improvements in access.Research Approach and ContributionsTo test these hypotheses, I follow a mixed-methods approach that combines quantitative analysis of trip activity data with survey data and spatial modeling techniques. I focus on BlueLA. (Abstract shortened by ProQuest).
