摘　　要：为了研究隧道被动发光导行反光环(下简称隧道反光环)对驾驶员瞳孔变化的影响,利用UC-win/Road软件对隧道反光环进行仿真模拟,采集了8名驾驶员的瞳孔数据,定性分析了不同行车速度下,反光环色彩对其瞳孔面积变化率影响的规律,并构建了三者之间的趋势面拟合模型。最后,对行车速度、隧道反光环色彩进行了单因素敏感性分析。结果表明:黄色的隧道反光环对驾驶员瞳孔面积变化影响最大;行车速度与驾驶员瞳孔面积呈正相关,隧道反光环色彩值与之呈负相关;行车速度对驾驶员瞳孔面积变化的影响起着决定性的作用。Different colors have been simulated using the UC-win/Road to study the impact of tunnel＇s aura color on changing rate of drivers＇ pupil. The data of eight drivers＇ pupil have been recordeda, qualitatively analyzed the changing rule of the drivers＇ pupil of different driving velocity and establishe the trend surface fitting model. Finally, the single factor sensitivity analysis was respectively carried out on tunnel color and driving velocity and compared the sensitivity of drivers＇ pupil. The results showed that drivers＇ pupil changed most when applied yellow on the tunnel＇ aura. Changing rate of drivers＇ pupil increases with the increasing of driving velocity but decreasing of color value. Driving velocity played a decisive role in the change of pupil area.
