The role of autonomous vehicles in future transportation systems and their impacts on a host of transportation-related outcomes for cities and regions continues to be a priority research area addressed by scholars and policymakers across disciplines. Many have focused on how vehicle ownership models will influence such outcomes, noting this factor as a key source of uncertainty. Some studies have begun to identify areas where future autonomous vehicle travel demand may exist relative to vehicle ownership models, including for beneficial purposes. To date, less attention has been devoted to the identifying travel activity and trip purposes that make people less willing to consider autonomous vehicle travel, which is the focus of this study. To address this topic, an intercept travel survey was conducted in Ann Arbor, Michigan in the spring of 2017. Respondents were asked to consider their willingness to use an autonomous vehicle for their current trip at a set of different locations throughout the city. Out of the 233 respondents interviewed, 30% stated that they would not currently consider autonomous vehicles for their trip. Observed travel relative to the survey sites for these respondents generally occurred in the denser, downtown area of the city. These respondents were more likely to be transit riders who did not live in higher-income neighborhoods. Such findings may carry implications for autonomous vehicles as part of mobility systems, though more research is needed to determine if these results are consistent between cities and travel purposes.
