Summary
This study addresses the potential of autonomous vehicles (AVs) to improve mobility access for persons with disabilities, a population representing over 60 million U.S. adults who often face transportation barriers. Motivated by the rapid advancement of AV technology and the lack of research on how these vehicles can accommodate diverse disability needs, the researchers aimed to gather direct feedback from individuals with disabilities who had firsthand experience with AVs. The goal was to move beyond abstract concepts of self-driving cars to capture specific impressions, concerns, and recommendations to inform future AV design and deployment. The research was conducted as a joint initiative between Rutgers University and Princeton University during the 2019 SmartDrivingCar Summit. Twenty-one adults with disabilities participated in four focus group sessions. The cohort included five individuals with visual impairments and sixteen with autism or related developmental disabilities; none had co-morbid physical disabilities requiring wheelchairs. The methodology involved a unique sequence where participants first rode a Local Motors Olli autonomous shuttle on the Princeton University football field for approximately five minutes, followed immediately by a 45-minute to one-hour focus group discussion. The rides were conducted in a controlled environment with an operator on board for safety, and the sessions were audio and video recorded to capture detailed feedback on initial impressions, in-vehicle experience, interest in future use, and specific concerns. The findings revealed overwhelmingly positive reactions to the AV experience. Most participants described the ride as comfortable, smooth, quiet, and safe, with many noting that the slow speed alleviated anxiety. Visually impaired participants appreciated the low step height and handrails, while those with developmental disabilities valued the quiet environment and large windows. Seventeen of the 21 participants expressed strong interest in using AVs in the future, citing the potential for increased independence, reduced reliance on family for transportation, and decreased feelings of isolation. Participants identified various desired destinations, including employment, education, and social venues. However, several concerns were raised regarding accessibility, safety, and usability. Recommendations included standardizing wheelchair lifts and kneeling features, improving seatbelt configurations to three-point belts, and enhancing on-board audio guidance. Safety concerns focused on the need for reliable technology in inclement weather, the ability to contact emergency services via the vehicle interface, and the potential need for an on-board attendant for troubleshooting. Additionally, participants emphasized the desire for on-demand availability rather than scheduled reservations. The significance of this study lies in its provision of direct, experience-based insights from persons with disabilities, a group often excluded from AV development discussions. The results highlight that while AVs hold great promise for enhancing mobility and independence for this population, specific design modifications are necessary to ensure universal accessibility and safety. The findings offer actionable recommendations for manufacturers and policymakers, such as improving vehicle interfaces, ensuring robust safety protocols, and designing for diverse sensory and physical needs. By addressing these barriers, the AV industry can better serve transportation-disadvantaged populations, promoting greater social inclusion and equity in mobility.
Key finding
Participants reported overwhelmingly positive impressions of the autonomous vehicle ride and expressed strong interest in using AVs to increase travel independence and reduce reliance on family members for transportation.
