摘要:
为减少高速公路纵坡路段的事故发生率，利用心生理检测仪采集驾驶员心率数据，使用V-Box采集道路高程和车辆实时速度数据，采用偏相关分析确定影响驾驶员心率增长率和速度差的显著性因素，分别构建驾驶员心率增长率和速度差与坡度之间的关系模型，通过心率增长率阈值和运行速度协调性，从驾驶舒适性角度确定安全坡度范围。研究结果表明：在纵坡路段行车时，驾驶员心率增长率随坡度增大而增加，速度差随坡度增大而增大，坡长与驾驶员心率增长率和速度差呈弱相关；设计车速为100 km/h的高速公路，上坡坡度应小于等于3.7%，下坡坡度应小于等于3.3%，因此建议纵坡坡度小于等于3.3%为宜。研究结果可为高速公路交通安全和人性化设计提供理论依据。
Abstract:
In order to reduce the accident rate on the longitudinal slope road section of the expressway,26 drivers were selected for the real-vehicle experiments to explore the relationship between the driver’s growth rate of heart rate and speed difference and the slope and slope length.The heart rate data of the drivers were collected by the cardio-physiological detector,and the road elevation and real-time speed data of the vehicles were collected by the V-Box.The partial correlation analysis was used to determine the significant factors that affected the driver’s growth rate of heart rate and speed difference,and the relationship models between the driver’s growth rate of heart rate and speed difference and the slope were respectively constructed.Through the threshold of the growth rate of heart rate and the coordination of running speed,the safe slope range was determined from the perspective of driving comfort.The results showed that when driving on the longitudinal slope road section,the driver’s growth rate of heart rate and speed difference increased with the increase of slope,and the slope length was weakly correlated with the driver’s growth rate of heart rate and the speed difference.For the expressway with a design vehicle speed of 100 km/h,the uphill slope should not be greater than 3.7%,and the downhill slope should not be greater than 3.3%.Therefore,it was recommended that the longitudinal slope should not be greater than 3.3%.The research results can provide theoretical basis for the traffic safety and humanized design of highway.
