摘要
道路环境直接或间接影响驾驶员反应。经实地调查统计分析可知:草原道路线形以长直线为主,平曲线半径大。草原道路景观单一。交通流量小,实际运行车速均高于设计车速。基于此实验结果,后续实驾实验中深入研究草原道路环境与驾驶员心率变化关系。结果表明:随着驾驶时间增加,实验驾驶员警惕性有不同程度的降低、易出现疲劳。
Road environment influences driver＇s reaction directly or indirectly.Research finding show： Basing on field survey and statistical analysis,long line is main alignment of the grassland road and the horizontal curve radius is large.Landscape of grassland road is single and traffic flow is less.And practical operation speed is higher than design speed.Basing on this finding,the relationship between grassland road environment and heart rate change of driver is further researched in following field experiment.Research finding show： with the increase of driving time,the precaution of driver decreases in different degrees,and driving fatigue may occur.
