The three revolutions in transportation — shared mobility, electrification and autonomous vehicles — will fundamentally change transportation around the world. Rigorous research and impartial policy analysis are urgently needed to understand the impacts of these transportation revolutions, and to guide industry investments and government decision-making. This newly-established program was launched by the UC Davis Institute of Transportation Studies (ITS-Davis) in November 2016 to address the growing need for research to assist and inform government and industry. The program leverages the 25 years of ITS-Davis pioneering interdisciplinary research on travel behavior, alternative vehicles and fuels, and land use, as well as a strong commitment for outcome-oriented, policy-relevant research.

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. The popularity of these services is particularly high among millennials and those living in the dense central parts of cities. Still, the reasons behind the adoption of these services and their impacts on the use of other transportation modes and on total travel demand are largely unclear. How are shared mobility services changing transportation demand and supply? This report provides useful insights to answer this question. The research explores the use of various types of shared mobility services in California, focusing in particular on the factors affecting the adoption and frequency of use of ridehailing services (such as those provided by Uber and Lyft), and the impacts that the use of these services has on other components of travel behavior. The authors analyze a dataset that they collected with a detailed online survey in fall 2015 as the first round of data collection in a panel study of emerging transportation trends and adoption of technology in California. More than 2,000 respondents, including millennials (i.e., young adults born between 1981 and 1997) and members of Generation X (i.e., middle-aged adults born between 1965 and 1980), completed the survey.

What Affects Millennials’ Mobility? PART II: The Impact of Residential Location, Individual Preferences and Lifestyles on Young Adults’ Travel Behavior in California

Young adults (“millennials”, or members of “Generation Y”) are increasingly reported to have different lifestyles and travel behavior from previous generations at the same stage in life. They postpone the time at which they obtain a driver’s license, often choose not to own a car, drive less if they own one, and use alternative non-motorized means of transportation more often. Several explanations have been proposed to explain the behaviors of millennials, including their preference for urban locations closer to the vibrant parts of a city, changes in household composition, and the substitution of travel for work and socializing with telecommuting and social media. However, research in this area has been limited by a lack of comprehensive data on the factors affecting millennials’ residential location and travel choices (e.g. information about individual attitudes, lifestyles and adoption of shared mobility is not available in the U.S. National Household Travel Survey and most regional household travel surveys).
