Abstract
This paper investigates the relationship between driver′s arousal level and eye-fixation-related potentials (EFRP) while driving. The experiment with driving simulator was conducted and the subjects were required to perform monotonous driving task, while measuring their electroencephalogram (EEG). Their arousal levels were evaluated based on the subjective questionnaire, alpha wave-power and lateral deviation. The results indicate that the peak amplitude of lambda response of EFRP decreases when the driver′s arousal level decreases. Furthermore, these results imply that EFRP would be a valid index estimating the driver′s behavior in lower arousal level.
