摘　　要：为了量化分析高速公路纵坡路段的驾驶舒适度,进行实车试验,采集驾驶员心生理数据、道路参数以及车辆运行速度数据。运用傅里叶变换转化驾驶员心率随机信号来研究心率变化的规律。采用偏相关分析,确定上、下坡路段影响驾驶员心率增长率的显著性因素。以交通工程学、人因工程学和心理学为基础,探究坡度和速度差对驾驶员心率增长率的影响,构建了基于心率增长率阈值的驾驶舒适度评价模型。研究结果表明:坡度、速度差与驾驶员心率增长率显著相关,而坡长与驾驶员心率增长呈弱相关;上坡路段行车时驾驶员心率增长率主要分布在15%~32%,坡度对驾驶舒适度影响较大;下坡路段行车时驾驶员心率增长率主要分布在15%~35%,速度差对驾驶舒适度影响较大。研究结果可为高速公路纵坡路段安全管理提供理论依据。In order to quantitatively analyze the driving comfort of the highway on the longitudinal slope section,real vehicle test were carried out to collect the driver s physiological data,road parameters and driving speed.Fourier transform was used to transform the driver s heart rate random signal to study the law of heart rate changes.Partial correlation analysis was used to determine the significant factors affecting the driver s heart rate growth rate on the uphill and downhill section.Based on traffic engineering,human factors engineering and psychology,explore the influence of slope and speed difference on the driver s heart rate growth rate,and build a driving comfort evaluation model based on the heart rate growth rate threshold.The research results show that the slope and speed difference are significantly related to the driver s heart rate growth rate,while the slope length is weakly related to the driver s heart rate growth rate.When driving on an uphill section,the driver s heart rate growth rate is mainly distributed between 15%and 32%,and the slope has a greater impact on driving comfort.When driving on a downhill section,the driver s heart rate growth rate is mainly distributed between 15%and 35%,and the speed difference has a greater impact on driving comfort.The research results can provide a theoretical basis for the safety management of highway longitudinal slope section.
