For passengers to become comfortable with automatic driving, it is important to clarify when they sense danger. For the sake of safety and reproducibility of dangerous situations, experiments using a driving simulator are preferred to experiments in actual traffic. However, drivers' sense of danger in a driving simulator has not been well studied. We conducted two experiments using a driving simulator to examine drivers' sense of danger. In Experiment 1, drivers followed a car. We measured driver perspiration when the forward car suddenly decelerated. Experiment 2 was a simulation of two platooning trucks. We observed the perspiration of the driver in the following truck. Results indicated a correlation between inverse Time- To-Collision and perspiration rate change. We analyzed the correlation between perspiration and car motion variables for practical application to automatic driving.
