基于视觉行为的长下坡路段彩色路面设置有效性研究

为研究高速公路彩色路面对驾驶员视觉行为的影响规律,采用Smart Eye Pro 5.7型非侵入式眼动仪记录了在彩色路面路段的驾驶员眼球运动数据,并选用瞳孔面积、XY视角、注视次数百分数、注视时间百分比、平均注视时间等眼动指标对数据进行分析。结果表明:彩色路面能够有效引起驾驶员的注意,但也影响了驾驶的舒适性。彩色路面会导致驾驶员对近处与远处的关注变换更为频繁。对于隧道出口同时又是转弯的彩色路面路段,驾驶员注意力分散,关注于弯道内侧,因此彩色路面设置的方式还有待改善。。

Research on the effectiveness of Colorful Pavement Based on Driver "s Visual Behavior in Long Downhill

In order to study the influence of colorful pavement on the drivers" visual behavior in long downhill, the paper use Smart Eye Pro5.7 eye tracking system to record the driver"s eye movement data in colorful pavement section, analyze eye movement index,such as pupil area, XY angle, percentage of fixation, percentage of fixation time and mean fixation time. The results showed that color pavement can effectively cause the driver"s attention, but also affected the driving comfort, its set manner need to be improved. Color pavement will cause the driver to focus on the near and far more frequent changes. For the section that is both tunnel exit and curve, the driver focused on the inside of the curve, colorful pavement should not be set.
