Research review on public acceptance of autonomous driving
(2.School of Information Engineering, Chang’an University, Xi’an, Shaanxi Province, China 710064)
【Abstract】The relevant studies in the field of public acceptance of autonomous driving are comprehensively sorted out and summarized. The connotation of acceptance is defined and explained from five aspects such as the possibility of and attitude to accepting the autonomous driving, degrees of understanding and trust, perception and focus, willingness-to-pay, and use preference. The methods for data collection and analysis used in the existing researches are compared and analyzed from the aspects such as the survey object selection, questionnaire design, survey and sampling schemes, model building and data analysis methods. The key factors impacting the public acceptance of autonomous driving are summarized. The influences of key factors on the public acceptance are analyzed. The problems and future research directions are pointed out. The research result indicates that most of the existing studies focus on the problems of accepting possibility of autonomous driving, attitude, and use preference. The research related to the willingness to pay is relatively rare. The public is generally positive about the autonomous driving, and have certain knowledge of autonomous driving technology and its related functions. The safety issue is people’s primary concern for the autonomous driving, while the concern degrees vary drastically with groups. People’s willingness to pay extra money for autonomous driving technology is not strong enough. The willingness-to-pay of respondents from developed countries is generally lower than that from developing countries. The personal psychological and physiological attributes, social population attribute, ethics, legal responsibility, and vehicle safety level and related attributes, vehicle automation level and related attributes, travel-related attributes, and environmental factor are several key factors influencing the public acceptance of autonomous driving. However, the quantitative analysis on the factors such as ethics and legal responsibility in existing research is still absent. The effects of some key factors such as gender, age, and income are still so controversial that further discussion is needed. In-depth research is needed to be carried out on representative analysis of samples, refined design of questionnaire and survey, and analysis of specific mechanisms of key factors.
