Supplementary material for paper: "Passengers Perceive more Uncertainty in Fully Automated Cars than in Manually Driven cars : An Online Crowd-sourced Animation study under Mixed Traffic Conditions"
What's in it
Abstract Automated cars have the potential to improve road safety and reduce traffic congestion. Not all objective benefits are perceived this way by society. Passengers may feel uncertain about the behavior, reliability, and intentions of fully automated cars, which can affect their overall experience. This study investigates the amount of psychological uncertainty that passengers perceive in fully automated and in manually driven cars. Using a crowd-sourced approach, participants reviewed scenarios in which the only difference was whether they were passenger in a fully automated car or in a manually driven car. Participants rated their perceived uncertainty after each scenario. The results show that passengers generally perceive higher psychological uncertainty in fully automated cars. The passenger's trust in the capabilities of a fully automated car seems to influence the psychological uncertainty that they perceive. Furthermore, the psychological uncertainty scores for different scenarios indicate a link between perceived risk and psychological uncertainty. Procedure & Participants To study perceived psychological uncertainty, we chose to let the participants use their own …
