Dose-response relationship between the psychophysiological responses of drivers and passengers and the physical quantities of vehicles during driving

Abstract

This study aims to establish an index for quantitatively evaluating the physiological and psychological fatigue of the driver and passenger while the automobile is in motion. The driver drove a circulation course of about 400 m per lap for three hours, measuring the physiological and psychological responses of the driver and passenger during a simple driving operation or operation to stop randomly within the course. We examined the time-series variation of fatigue through physiological and psychological response measurement during automobile driving. We report findings on the fatigue of the driver and passenger during a three-hour drive derived from physiological and psychological responses measured in an actual vehicle experiment.
