摘　　要：为评估和改善驾驶人应激反应能力,提升行车安全,为职业驾驶人的筛选提供理论依据,分析了驾驶人应激响应行为,创新性地提出了评估驾驶人应激操作行为的操作得分指标,并以制动减速安全距离模型为理论依据,结合驾驶人操作行为数据和车辆运动数据建立了驾驶人应激反应能力评估算法,将驾驶人的应激反应能力分成4个等级。为验证评估算法的可行性,借助应激处置绩效得分,以驾驶模拟器为平台,培训驾驶人应激反应能力,通过对被试的操作得分与应激处置绩效进行回归分析发现,操作得分与应激处置绩效具有显著的线性关系,且驾驶人制动反应时间符合以往学者的研究结论,由此验证了评估算法的可行性和有效性。In order to evaluate and improve stress response of drivers and traffic safety,and to provide references for choices of professional drivers,response behaviors of drivers under stress are analyzed,and indicators of performance score is innovatively put forward.An evaluation model for stress response of drivers is established based on a model of brake deceleration safety distance and data of operation behaviors and vehicle motion.Stress response of drivers is divided into four levels.In order to verify the feasibility of the model,drivers are trained in driving simulators;their performance scores of stress response are analyzed.The regression analysis of operation score and response performance of the drivers show that the two indicators have a significant linear relationship.The braking reaction time of drivers is consistent with previous studies,which verifies the feasibility and effectiveness of the evaluation model.
