Public preferences and concerns regarding automated vehicle-based transportation services: a mechanism analysis from a Kentucky survey

Prior research on Automated Vehicle (AV) transportation services has largely concentrated on specific cases, leading to a narrow comprehension of wider public mobility requirements in AV deployment. Additionally, the impacts of socio-demographics on AV transportation preferences remain underexplored, hindered by limitations in current modeling methodologies. Moreover, mediating roles of safety between socio-demographics and AV transportation preferences lack quantitative validation. This study aims to uncover the reasons behind public preference for AV-based services and investigate safety's mediating effects on these preferences. In a survey conducted in Kentucky, USA, with 673 responses, the most preferred uses for AV services were post-alcohol rides, airport shuttles, and long-distance travel. Urban areas showed a higher preference for AV services. Age, gender, urbanization, affordability, travel needs, and exposure to AV technology significantly influenced these preferences. The study underscores a high demand for AV services while validating safety concerns as a major barrier to their widespread adoption.
