中文摘要：

草原公路在线形、景观、交通、光环境等方面都有特殊性。不同熟练程度的驾驶员在典型草原公路上行驶时表现出不同的动态视觉规律和视觉疲劳特性,驾驶安全水平差异比较明显。本文按照熟练程度将驾驶员分为两组,比较并分析两组有效样本在视觉搜索、视野范围和驾驶安全等方面的表现出的动态视觉规律的差异性,进行非参数检验,得出熟练程度对草原道路交通环境下驾驶员的动态视觉特性具有显著性影响。

英文摘要：

The prairie highway has the characteristics such as terrain flat, sparsely populated, monotonous landscape, different profi- ciency driver showed different dynamic visual regular pattern and visual fatigue characteristic in typical prairie highway. We select the drivers of different driving proficiency as experimental sample and divide them into two groups, collect the eye movement parameters of the effective samples on the typical prairie highway, Comparing and analazing the differences in dynamic visual search scope, vision field and Driving Safety of different proficiency drivers. According to non - parametric test of different proficiency driver sample, it con- cludes that the proficiency has significant influence on driver~ dynamic visual characteristics in prairie highway traffic environment.
