Abstract：
The eye fixation characteristics of drivers can properly express their visual information processing, and therefore the change rules of thedriver's eye fixation characteristics can be used to evaluate safety and comfort while driving in a highway tunnel with various interior materials applied on the sidewalls. For the Lushan Tunnel project on the Baoteng highway in the Yunnan Province, the Smart Eye Pro 5.7 non-intrusive eye tracking system was used to create an evaluation index of the eye fixation characteristics of drivers in the highway tunnel. The fixation duration, fixation area, pupil changes and change rates regarding 3 kinds of interior materials were used as the research objects to carry out real vehicle driving tests, and the changes of drivers' eye fixation characteristics under 3 testing conditions were consequently derived. Testing results show that the eye fixation characteristics for driving in a highway tunnel with applied energy-saving self-illuminated interior material are superior, featuring minimal and smooth changes of pupil diameter. It is thereby verified that the energy-saving self-illuminated interior applied material could remarkably improve the safety and comfort level of drivers in the highway tunnel.
