摘要
以高速公路隧道路段驾驶员视点变动为研究对象,在传统的平均注视时间动视点指标、注视时间比率动视点指标基础上,根据大量动视点行车实验,考虑驾驶员注视时间、注视频率、视力角等眼动特征,提出了基于视点平面分布的动视点指标,以评价驾驶员视觉信息加工水平.利用该指标对隧道进口平曲线安全性进行评价,结果表明平曲线半径不宜小于450 m.
Driving experiments were conducted to investigate drivers＇ eye movements at the expressway tunnels. With a consideration of the average fixation time, the fixation proportion, the fixation dura- tion, the fixation frequency and the visual lobe, a new eye movement index based on plane distribution of viewpoint was proposed to evaluate the driver＇ s visual information processing level. The index was applied to safety evaluation of horizontal alignment at tunnel entrance, and the result indicated that the rational radius of horizontal curve should be no less than 450 m.
