One of principal causes of car accidents is low arousal level of driver. Drivers arrive their destination under an appropriate arousal level. Basic research was done to develop a portable arousal monitor and to evaluate the arousal level of drivers. An arousal monitor which can simulantaneously measure the skin impedance change and EEG was designed and tested. The relationship among three parameters was studied and was used to determine the index of skin impedance level depending on arousal level.
