摘　　要：利用EMR-8B眼动仪，以高速公路隧道进出口驾驶员的瞳孔变化为研究对象，在大量行车试验基础上，针对明暗适应中的视觉震荡现象，选取换算视觉震荡持续时间作为驾驶员视觉舒适度评价指标，用于评价隧道进出口驾驶员视觉负荷程度及行车安全性。结果表明：当隧道进出口行车速度控制在85km·h^-1以下时，能保证驾驶员良好的视觉舒适度，并得出高速公路隧道进出口停车视距应比现行规范增加20～30m。By using EMR-8B eye movement recorder, selecting driver＇s pupil variety of freeway entrance and exit as research object, on the basis of driving experiment, refered to the phenomena of visual turbulence during light and dark adaption, the conversion duration for visual turbulence was selected as evaluation index of driver＇s visual comfort degree which was used to evaluate the visual load degree and driving safety of tunnel entrance and exit. The results indicate that the driving speed should not surpass 85 km · h^-1 in order to guarantee driver＇s visual comfort; the stopping sight distance should increase 20～30 m compared to the present standard for tunnel entrance and exit.
