Abstract

This study was to examine to the CNS(Central Nervous System) responses of elderly drivers at the green, yellow, and red signal types. To examine this result, the older adults over age 65 who has more than 5 years of driving experience participated this experiment. In addition, we used audio-visual film clips as the stimulus than driving simulator, because the CNS reponses are sensitive to movement such as steering wheel. While subjects were watching one car's driving among green, yellow, or red signal types at the intersection, we measured their EEG(electroencephalogram) using monopolar electrodes from Fz, Cz and Pz sites. As a result, relative sizes of beta waves were changed due to the signal type conditions, and pre- and post-time of entering the intersection at the measured sites, separately. It suggests that the elderly drivers' CNS responses were different by the signal types.
