Relationship Between Eye Movement Index and Horizontal Alignment at Entrance of Highway Tunnel
Zhen Yu Yang · Journal of Tongji University · 2008
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 duration,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.
