People with disabilities face many travel barriers. Autonomous vehicles and services may be one solution. The purpose of this project was to conduct a systematic review of the grey and scientific literature on autonomous vehicles for people with disabilities. Scientific evidence (n = 35) was limited to four observational studies with a very low level of evidence, qualitative studies, reviews, design and model reports, and policy proposals. Literature on older adults was most prevalent. Grey literature (n = 37) spanned a variety of media and sources and focuses on a variety of disability and impairment types. Results highlight opportunities and barriers to accessible and usable AVs and services, outline research gaps to set a future research agenda, and identify implications for policy and knowledge translation. People with disabilities are a diverse group, and accessible and usable design solutions will therefore need to be tailored to each group's needs, circumstances, and preferences. Future research in diverse disability groups should include more participatory action design and engineering studies and higher quality, prospective experimental studies to evaluate outcomes of accessible and usable AV technology. Studies will need to address not only all vehicle features but also the entire travel journey.
