Driver’s Psychophysical Performance at Urban Tunnel
The objective of this work is to investigate how driving performance is varied in psychophysical phenomenon in urban tunnel. Twelve drivers participated in the real road experiments study, and they were classified into three groups according to age and gender. In experiments, by using the physiology recording instrument and Tobii Studio eye tracker system, the heart rate (HR) and eye movement, the pupillary change of the drivers at the entrance and exit of urban tunnel were separately investigated. Experimental results indicate that drivers’ performance while driving through an entrance and an exit are highly variable at speed, at HR increasing rate, and pupil diameter increasing rate. Middle-aged females and older-aged males are more sensitive to tunnel environment than middle-aged males. There is non-significant effect of tunnel zone on the visual scanning for all the drivers in this study.
