摘要
通过心率增长率指标的提出,建立了驾驶员行车的心理生理反应与道路纵断面线形、车速等之间的定量关系模型,实测数据与模型计算数据进行对比,模型计算的精度比较好,能够反应驾驶员实际运行过程中的心率增长的变化。在对山区双车道三级公路上实测速度的统计分析的基础上,使用数理统计和分析的方法,得到速度累计频率分布曲线,确定85%位速度为51km/h。最后提出了山区双车道三级公路纵坡坡度的安全值为7%。
This paper established the quantitative model between driver＇s physiological and psychological response defined by increased rate of heart beat, and highway vertical geometrical alignment and nmning speed.This model was proved capable of describing the response of drivers during driving through the contrast between field data and model calculated data. Based on surveyed speed data on the third class mountain area highway, the statistics method was used to draw the speed distribution curve and it was found that the 85 percentile speed was 51 km/h. Finally this paper suggested the safe slope grade for the third class mountain area highway should be 7%.
