Research on driving visual comfort of two?lane mountainous road based on traffic safety evaluation

In order to obtain the quantitative relationship between multisource data from road landscape and driving visual comfort in two-lane mountainous road, we collected driver's eye movement environment through real vehicle tests. The threshold segmentation method target area ratio are used process image, spatial enclosure degree is express sense of closure. addition, an HSV color model established characterize perception mountain highway environment. Combining with amount information, calculation information obtained. According characteristics normal distribution pupil ratio, five grades level proposed, regression established. study found that there a significant negative correlation comfort. When less than 0.338, higher, which conducive safety. However, when exceeds 0.644, decreases significantly, detrimental
