摘　　要：驾驶员应激反应和减速行为直接关系到高速出口段交通安全,而出口行车条件(出口提示距离、运行速度)是影响驾驶员应激反应与减速行为的关键因素。为此,在设计速度100 km/h的高速公路出口路段开展了以提示距离和运行速度为自变量的实车正交试验,采集并分析驾驶员生理指标(皮肤电导反应,SCR)和驾驶行为指标(最大减速度,d max)。试验结果表明:①运行速度变化对SCR、d max均有显著影响;②提示距离变化对SCR有显著影响,但对d max没有显著影响;③SCR与d max呈正相关关系。试验结果为深入理解高速公路出口路段驾驶员生理反应与驾驶行为特征提供了方便,对提高行车安全具有参考意义。The driver s stress response and deceleration behavior are directly related to the traffic safety of the expressway exit section,and their key influencing factors are driving conditions(exit guide distance、running speed).Therefore,the real vehicle orthogonal test with the guide distance and running speed as independent variables was carried out on the expressway exit with a design speed of 100 km/h.Skin conductance response(SCR)and maximum deceleration(d max)were collected and analyzed as driver physiological indicators and driving behavior indicators,respectively.The results showed that:①The change of running speed has a significant effect on SCR and d max.②The change of guide distance has a significant impact on SCR but has no significant effect on d max.③SCR is positively correlated with d max.The test results provide a more in-depth understanding of the driver s physiological response and driving behavior characteristics of the expressway exit section,and have reference significance for improving driving safety.
