Abstract

Advanced driver assistance systems (ADAS) in passenger vehicles can improve highway safety. ADAS place powerful, yet imperfect, automation in the hands of drivers who hold both misconceptions and reservations about ADAS. There is little previous research on drivers' knowledge of ADAS, and even less on sources of information drivers use to inform their knowledge. The present study addressed this gap, testing hypotheses about influences on understanding of seven ADAS in 634 licensed US drivers (aged 18-82). Multiple regression to predict self-assessed driver characteristics revealed: (a) Drivers who rated themselves as more technically sophisticated tended to be young and male, to be at once less objectively knowledgeable and more confident of their knowledge of ADAS, to avoid car dealers for ADAS information, and to value brand status; (b) Drivers who rated themselves as faster to adopt new technology also tended to be male but to be more objectively knowledgeable about ADAS and to prefer learning about ADAS from owner manuals; (c) Drivers who rated themselves as more confident in using novel vehicle technology tended to be young males with greater objective knowledge of ADAS who valued "hands-on" ADAS experience; (d) Drivers who rated themselves as more concerned about vehicle safety tended to be female, to value crash data, and to rely on hands-on experience to learn about ADAS; (e) Drivers who rated themselves as having greater aesthetic concerns tended to rely on information on styles, colors, wheels when buying a new car and preferred specific ADAS components. Neither of the latter two differed in objective ADAS knowledge. These results make a novel contribution in revealing how driver demographics and characteristics are related to preference for specific sources of information on ADAS and objective knowledge of ADAS. These results can inform future efforts to increase driver understanding of the capabilities and limitations of ADAS and hence increase public safety.
