摘要： 草原公路具有直线长、纵坡小、景观单一的特点，驾驶员在行车过程中极易产生驾驶疲劳。通过采集、分析驾驶员以自由速度实驾试验的心率变异生理指标，通过定量分析得出驾驶员 在连续驾驶120 min左右出现驾驶疲劳现象。运用灰度分析理论，分析驾驶员心率变异指标中时域分析指标与驾驶疲劳的关联性，得出各时域分析指标与驾驶疲劳的关联程度。

Abstract: The characteristics of grassland highway are long straight line, slight grade, and monotonous landscape. Drivers are liable to become tired when they travel on this kind of road. Drivers’ heart rate variability(HRV) data were collected when they travelled along grassland highway at free speed in the field. And after quantificationally analyzing these data, it is concluded that drivers always begin to become tired after they continuously drive 120 minutes. Using gray scale analysis theory, the relationship between time domain indicators of drivers and driving fatigue were studied, and the degree of correlation of them was found.

Key words: traffic engineering, prairie highway, fatigue, selection of indicator, relation analysis
