Establishing Face and Content Validity of a Survey to Assess Users’ Perceptions of Automated Vehicles

Transportation Research Record Journal of the Transportation Research Board · 2020 · 45 citations

Fully automated vehicles hold promise for providing numerous societal benefits, including drastically reducing road fatalities. However, we know little about the adoption practices of individuals related to automated vehicles. To assess transportation users’ perceptions of automated vehicles, a 40-item survey was designed using guidance from several technology acceptance models. A focus group was used to assess face validity to ensure the items appeared credible and understandable to the laypers…

Older Drivers' Experience With Automated Vehicle Technology: Interim Analysis of a Demonstration Study

Frontiers in Sustainable Cities · 2020 · 43 citations

Older adults (> 65 years) account for 20% of the US population but are over-represented in multiple-vehicle crashes. Automated vehicles (AVs) may hold safety benefits for older drivers, if they adopt this emerging technology. Therefore, this study is using a randomized, crossover design with pre- and post-exposure surveys, to quantify older drivers’ perceptions, who were exposed to a simulator running in automated mode and riding in a highly automated shuttle (SAE Level 4). An interim analysis (…

Construct Validity and Test–Retest Reliability of the Automated Vehicle User Perception Survey

Frontiers in Psychology · 2021 · 39 citations

= 84). The AVUPS, or any combination of the three subscales, can be used to validly and reliably assess adults' perceptions before and after being exposed to AVs. The AVUPS can be used to quantify adults' acceptance of fully AVs.

Lived Experiences of People with and without Disabilities across the Lifespan on Autonomous Shuttles

Future Transportation · 2024-01-05 · 6 citations

As an emerging, alternative mode of transportation, an in-depth understanding of autonomous shuttle (AS) experiences among all age groups, with and without disabilities, may impact acceptance and adoption of the AS, shape industry guidelines, and impact public policy. Therefore, this study analyzed qualitative data from older (n = 104), younger, and middle-aged (n = 106) adults and people with disabilities (n = 42). The data were obtained by asking participants four open-ended questions from an…

Veterans’ Perceptions of Shared Autonomous Electric Shuttles: A Pre- and Post-Exposure Assessment

Sustainability · 2025-01-10 · 3 citations

Veterans often face transportation barriers, but advances in technology enable real-world testing of shared autonomous electric vehicles as potential energy-efficient solutions. While previous research has assessed civilians’ perceptions of autonomous vehicles (AVs), veterans—due to unique military experiences and health conditions—represent a distinct demographic. This study investigates veterans’ perceptions of autonomous shuttles (ASs) to assess whether these innovations may foster sustainabl…
