为了掌握驾驶员在高原环境下行车时的心理和生理反应状况,提高高原公路行车安全性,利用生物反馈仪等设备对314国道高原路段上行车的驾驶员进行实地行车检测。在理论分析的基础上,整理分析实测数据,建立驾驶员心率增长率和高原区公路线形组合、海拔之间的关系模型。分析结果表明,驾驶员的心率增长率会随着海拔的升高而增高;上行和下行时,线形组合值的增大均导致驾驶员心率增长率的增加,并且增加的趋势基本保持一致;海拔和线形2因素一起作用时,驾驶员心率变化更显著,海拔越高、线形组合值越大,驾驶员心率增长率越大。
In order to grasp the psychological and physiological responses of drivers when driving in high altitude environment and to improve the driving safety of highland highway, the device of bio-feedback instrument and so on is used to detect the driving of the drivers on the highways in No.314 National Highway. Based on the theoretical analysis, the data collected and analyzed are analyzed to establish a model of the relationship between driver heart rate growth rate and the linear combination of the highway in the plateau area and the elevation. The results show that the driver's rate of increase of heart rate will increase with the elevation. When the line combination increases, the driver's rate of increase of heart rate will increase and the trend of increase will be basically the same. When working with the linear 2 factors, the driver's heart rate changes more significantly. The higher the altitude, the greater the linear combination value, the greater the driver's heart rate growth rate.
