【摘要】：林区冰雪道路具有等级低、视距短、路面附着力小、平曲线半径小、纵曲线变化剧烈等基本特征,给木材生产运输的驾驶员带来了较大的生理和心理压力。本文以北方林区冰雪道路上6名驾驶员的眼动实驾试验数据为基础,分析了驾驶员在不同直线长度下的冰雪道路上的眨眼、注视和扫视行为,得出了驾驶员在冰雪道路上行车时的平均眨眼持续时间、平均瞳孔面积变化率呈现相似的周期性变化规律,平均扫视幅度在中长距离上具有显著变化规律,确定了在北方林区冰雪路面上驾驶员的最佳视觉舒适性直线段长度,为下一步研究驾驶员的生理指标变化规律提供理论参考。
[Abstract]:The ice and snow roads in forest area are characterized by low grade, short visual distance, small adhesion of road surface, small radius of flat curve and sharp change of longitudinal curve, which bring great physiological and psychological pressure to the drivers of timber production and transportation. Based on the experimental data of eye movement driving of 6 drivers on snow and ice roads in northern forest area, this paper analyzes the blinking, gazing and scanning behavior of drivers on ice and snow roads with different linear lengths. The results show that the mean blinking duration and the mean pupil area change rate of the driver on the ice and snow road are similar to each other, and the mean sweep amplitude has a significant change in the middle and long distance. The length of the optimal visual comfort line segment of the driver on the ice and snow pavement in the northern forest area is determined, which provides a theoretical reference for the further study of the physiological index variation law of the driver.
