Abstract
Electroencephalogram (EEG) is a widely used experimental tool in psychological research. In this study, we used EEG to research the driving safety by measuring the dynamic changes of drivers' emotions in a long tunnel. Through the study whether there was a tunnel, and whether there was a large amount of traffic flow in the tunnel, we found a long tunnel only makes a slight negative effect on driver's emotion, but a large amount of traffic flow could make an obvious negative effect on driver's emotion. As driver's negative emotions could lower the driving safety in the tunnel, we should control the traffic flow in the tunnel to reduce the possibility of congestion.
