Factors influencing the perception of safety in automated vehicles interiors

While driving automated, the driver becomes a passenger and the relief from the driving task allows the occupants to use and enjoy their travel time for secondary activities. The subjective driving experience, perception of safety and the resulting trust are essential for the acceptance of automation. Within this contribution we provide an overview of factors influencing the need for safety based on both a broad literature review and an online survey. A self-reflective questionnaire was created to determine the participants’ personal willingness to take risks and their perception of safety in vehicles. The focus was on the factors "environmental factors" and "protective effect". The participants were largely able to answer the questions targeting subjective safety. In particular, questions regarding "environmental factors" could be answered precisely in the online format. The differentiability into various aspects of the “protective effect” was not conclusively possible in the online format.
