A major cause of traffic accidents has been found in the human factors involved in driver's awareness during driving, and the effect of alarm was reported as the increase of awareness and the improving effect for property of perception, cognition and judgment of the driver. The arousal stimulus for driver by auditory-visual alert also affects to the physiological condition and the autonomic nervous system (ANS). Recent developments in multi near-infrared spectroscopy (MNIRS) have enabled the arousal level apparent with brain activity by measurement of hemoglobin concentrations as cerebral blood volume, as well as the ordinary biological signals like heart beats, finger plethysmogram and pulsation waves. In this study, the three kinds of auditory alert as pre-information, sound alert and voice guidance were used for adaptive assisting systems for the elderly driver and the influence of these alerts on the driver's psychosomatic state was examined using driving simulator for 30 minutes driving. Experiment was conducted with the subjects in a driving position as they were partially awakened by auditory-visual alert, repeatedly and measured their biological properties. As the results, after taking the effects of the adaptive assisting alert systems, the effect of arousal and awareness improvement was recognized in the subjects and the activation of cerebral blood volume was observed according to the amount of the stimulus and combination of awareness modal as auditory alert system.
