The purpose of this research is to develop the Phase 2 of the research project “Panel Study of Emerging Transportation Technologies and Trends in California” using data collected in 2015 as part of a previous project and new data collected in this new project. The analysis of data will allow investigate the evolution over time of individual attitudes and lifestyles, and the relationships among residential location, vehicle ownership, travel behavior and the adoption of shared mobility.

Changes in socio-demographics, individual lifestyles, the increased availability of modern communication devices (smartphones, in particular) and the adoption of emerging transportation technologies and shared-mobility services are quickly changing the way individuals travel. This panel study will improve the understanding of the impacts of emerging technologies and shared mobility services such as ride-hailing (e.g., Uber and Lyft) and pooled ridehailing services (e.g., UberPOOL and Lyft Line) on vehicle ownership and travel behavior (e.g., the use of other modes), while controlling for other changes in transportation trends in California through the application of a unique longitudinal approach.

This panel study will improve the understanding of the impacts of emerging technologies and shared mobility services such as ride-hailing (e.g., Uber and Lyft) and pooled ridehailing services (e.g., UberPOOL and Lyft Line) on vehicle ownership and travel behavior (e.g., the use of other modes), while controlling for other changes in transportation trends in California through the application of a unique longitudinal approach.

The use of longitudinal data will allow researchers to better assess the impacts of lifecycle, periods and generational effects on travel-related choices, analyze components of travel behavior such as the use of shared mobility services among various segments of the population and its impact on vehicle ownership over time. Further, it will help researchers evaluate causal relationships between variables, thus supporting.
