A Study on Physiological Signals While Driving in Long Tunnels

The purpose of this study is to investigate the psychological states of optimal and safe driving condition by measuring various physiological signals such as EEG, EOG, ECG, GSR and SKT while driving in long tunnels. During driving through long tunnels on express highways, some problems may occur. So Experiments are conducted in Juk-Ryoung tunnels that are located in Korea and Kanetzu tunnels in Japan. We investigated some problems generally occurred from corner segment from Juk-Ryoung tunnels and the effects of delineation systems from Kanetzu tunnels along with tendency to sleepiness in long time driving. As a result of this study a driving simulator is used to simulate driving inside a tunnel and changes in physiological signals are recorded.
