高海拔地区驾驶员心率-反向曲线间直线长度-车速关系分析

Analysis of Relationship of Driver' s Heart Rate with Straight Length in Reverse Curve and Vehicle Speed in High Altitude Area

为提高高海拔地区道路的安全性,采用行车试验方法,通过多导生理测试仪、动态GPS等仪器采集驾驶员在高海拔地区一级公路反向曲线间直线段上行驶过程中的心率、汽车运行速度等数据。分析驾驶员心率变化与反向曲线间直线长度及汽车运行速度的关系,利用SPSS软件建立了高海拔地区驾驶员心率与反向曲线间直线长度和汽车运行速度的回归模型。从驾驶员在反向曲线路段运行的安全性出发,基于驾驶员心理生理特征,确定了适应驾驶员行车心理的高海拔地区一级公路反向曲线间最小直线长度,提出了高海拔地区一级公路反向曲线直线段的限速值,以期提高高海拔地区反向曲线路段的安全性。

In order to improve the highway safety in high altitude area,the data such as driver＇ s heart rate and vehicle speed in straight sections of reverse curve of first grade highway in high altitude area are collected by using driving test method,multiple physiologic tester and dynamic GPS. The relationship among driver＇ s heart rate,straight length in reverse curves and vehicle speed are analyzed. The regression model of driver＇s heart rate,straight length in reverse curves and vehicle speed in high altitude area is established by SPSS.Considering driver ＇ s safety in reverse curves of highway,the minimum straight length meeting driving mentality in reverse curves of first grade highway is determined in high altitude area based on driver ＇ s psychological and physiological characteristics,and the speed limit for the straight length in reverse curves of first grade highway in high altitude area is proposed to improve the driving safety in reverse curves of road sections in high altitude area.
