摘要驾驶员的眼动特性能很好地表现视觉信息处理过程，可通过驾驶员在高速公路隧道内行驶过程中的眼动特性变化规律来分析公路隧道侧壁采用不同内装材料条件下照明环境所带来的行车安全性和舒适性。文章运用Smart Eye Pro 5.7 型非侵入式眼动仪系统，以高速公路隧道驾驶员行驶过程中的眼动特性为评价指标，基于云南宝腾高速公路鹿山隧道工程实例，对三种内装材料下的注视持续时间、注视区域、瞳孔变化及变化速率进行了实车试验，得出了驾驶员在上述3种工况下的眼动特性变化规律。试验结果表明，在同种条件下使用蓄能自发光内装材料的公路隧道内驾驶员的注视特征明显优于使用其它材料的工况，瞳孔直径变化最小、变化率最平稳，即蓄能自发光涂料能显著提高驾驶员行车进入隧道过程中的安全性和舒适性指标。

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.
