Horizontal curve radius and vehicle speed in high-altitude area based on driver's heart rate

为保证高海拔地区道路交通安全运行,采用行车试验方法,通过心率血氧测试仪、五轮仪等仪器采集驾驶员在高海拔地区一级公路不同海拔行驶过程中的心率、血氧及车速等数据,分析驾驶员心率变化与平曲线半径及车速的关系,建立了高海拔地区一级公路驾驶员心率与平曲线半径、车速的回归模型。从驾驶员安全出发,基于驾驶员生理心理特征,确定了适应驾驶员心理生理的高海拔地区一级公路平曲线的安全临界半径,提出了高海拔地区一级公路平曲线路段的限速值,为高海拔地区一级公路平曲线半径和限速值提供了参考。

To ensure the operation safety of highways in high-altitude area,a driving test method is applied to collect driver's heart rate,oximetry and vehicle speed in highway of high-altitude area by the heart rate tester and five-wheel meter,the relationship among driver's heart rate variability,the horizontal curve radius and vehicle speed is analyzed,the regression model of driver's heart rate,horizontal curve radius and vehicle speed in high-altitude area is established. Considering driver's safety,based on the driver's physiological and psychological characteristics,safety critical horizontal curve radius of highways fit for driver's psychology and physiology is determined in high-altitude areas,and the speed limit of horizontal curve section of highways in high altitude areas is proposed. The results provide reference for research on horizontal curve radius and speed limit of highways in highaltitude areas.
