摘要
从驾驶员动态视觉角度出发,应用UC-win/Road仿真软件对多种隧道反光环间距设置方案进行仿真模拟,并利用Tobii眼动仪对多名驾驶员展开仿真模拟实验。根据实验数据定性分析了不同行车速度下,反光环间距对驾驶员瞳孔面积及其变化率的影响变化关系,并利用Matlab中的rstool函数构建了速度、反光环间距及驾驶员瞳孔面积三者之间的趋势面模型。研究结果表明,行车速度与驾驶员瞳孔面积呈正相关,隧道反光环间距值与驾驶员瞳孔面积值呈负相关;并根据驾驶员心理状态与其瞳孔面积变化率的关系,得到不同行车速度下隧道反光环间距对驾驶员心理状态影响情况表;根据此表及驾驶员心理紧张状态与行车安全的关系,提出了不同速度下隧道反光环间距设置情况推荐值。
From the driver＇s dynamic visual angle, the scheme of tunnel＇s aura set spacing was simulated using the UC- win/Road simulation software and many drivers were equipmented using Tobii eye trackingt equipment. According to the experimental data, the influences of different intervals on drivers＇ pupil area and the change rate of drivers＇ pupil area under diffirent speeds were qualitatively analyzed, the trend surface among driving velocity, tunnel aura interval and drivers＇ pupil area by the function of rstool in matlab model was funded. The experimental results showed that the speed and the pupil area were positively correlated and the setting spacing and the pupil area were negative correlated. According to the relationship between the drivers＇ mental state and the pupil area rate, the tunnel aura interval under different driving speeds of drivers＇ mental state affect table was got. According to this table and the relationship between driver＇s psychological stress and the driving safety, the recommended value of the tunnel aura interval under different speeds was put forward.
