The Adoption of Shared Mobility in California and Its Relationship with Other Components of Travel Behavior

Emerging technologies and shared mobility services are quickly changing transportation. These services are particularly popular among millennials, and in dense central parts of cities. Still, the reasons behind the adoption of these services, and their effects on the use of other transportation modes, total travel demand and vehicle ownership are largely unclear. This study investigates the relationships among the adoption and frequency of use of shared mobility services and other components of travel behavior and auto ownership, through the analysis of a comprehensive dataset collected in Fall 2015 in California. The available data include information on personal attitudes, living arrangements and residential location, awareness, availability and frequency of use of shared mobility services (including car sharing, bike sharing, and on-demand ride services such as Uber and Lyft), average monthly spending and limitations to the use of shared mobility, among other dimensions. The data were collected from 2400 millennials and members of the Generation X, selected using a quota sampling approach from the six major regions of California and three neighborhood types. We estimate multivariate models to investigate the factors affecting the adoption and frequency of use of shared mobility services, the impact of residential location and neighborhood characteristics on these choices, and the relationships between the adoption of shared mobility and respectively (1) the use of other travel modes, including driving alone and public transportation, (2) auto ownership, and (3) the willingness to change the level of auto ownership. The study will provide important information on the effects of new mobility services on other components of travel demand, vehicle miles of travel (VMT) and auto ownership, and it improves the understanding of emerging trends in society, and their potential role in affecting transportation sustainability.
