Abstract
To realize a comfort of automatic driving, it is important to clarify when passengers sense the danger. Experiments of dangerous situations using adriving simulator is preferred to the experiments in actual traffic for the sake of safety and reproducibility of the dangerous situations. Howeverit is not well studied that how much the driver's feel sense of danger inthe driving simulator. Therefore the authors aimed at the clarification of driver's sense of danger during driving in the driving simulator. Further, the authors analyzed the correlation between perspiration and car motion variables for the practical application of automatic driving.
