Abstract:Over the past 20 years, car-sharing technology has become an important transportation option in population-dense, car-centric cities in the U.S. as it provides mobility and promotes public transit ridership without vehicle ownership. For successful implementation, procar-sharing policies and incentives have also actively supported the car-sharing programs. Members of low-income communities may benefit especially from the technology due to lower rates of vehicle ownership and high dependency on public transit. To maximize the benefit, it is important to understand the extent of car-sharing services within transportation Environmental Justice (EJ) population and travel behavior of individuals using car-sharing services. In this study, social workers and transportation engineers collaborate to understand the needs, accessibility, affordability, and willingness to use car-sharing. A mixed methodology was used including spatial analysis, mathematical modeling and qualitative focus group. For quantitate analysis, the 2017 National Household Travel Survey (NHTS) data was used to investigate the effects individuals’ socio-economic characteristics, travel behavior and technology access on car-sharing usage. Zero inflated binomial regression method was used to investigate the relationships between sociodemographic, travel behavior and financial related variables and car-sharing usages. The results indicate that individuals experience financial burden tend to use car sharing service as their mobility option along with rideshare service. Focus group was conducted with service providers providing assistance in low-income communities to assess their awareness of and sense of clients’ willingness to use car-sharing. The results showed that the participants were relatively unfamiliar with car-share programs than its shared-mobility counterpart, ridesharing. The participants also identified that affordability and technological barrier besides a lack of familiarity and consequence misconception as the potential causes of the lack of awareness or willingness to use car-sharing service.
