| 摘 要： | 随着年龄的增长,老年驾驶人的感知认知能力、判断决策能力及操作反应能力均出现衰退,进而导致其交通风险感知和应激反应能力发生变化。为了研究风险情景下老年驾驶人的应激操作反应特性,设计并搭建了行人与机动车、非机动车与机动车、机动车与机动车冲突的道路交叉口风险虚拟试验场景;分别招募了15名中青年与老年驾驶人进行了驾驶模拟试验,采集驾驶过程中驾驶人的操作行为及车辆运行数据,选取相关的指标对试验进行分析。结果表明,老年驾驶人在各风险情境下的反应时间与制动踏板行程总体上比中青年驾驶人长;而在高风险驾驶场景下,老年驾驶人的纵向加速度的波动幅度比中青年驾驶人大,其中有10名老年驾驶人发生了碰撞事故,占所有受试者的比例为33.3%。研究结果为交通安全政策制定者的措施制定提供一些提高老年驾驶人驾驶安全性的理论依据。

| Abstract: | As age increases, the cognitive perception, decision-making ability, and operational response ability of elderly drivers all decline, leading to changes in their traffic risk perception and stress response ability. In order to study the stress response characteristics of elderly drivers under risk scenarios, a virtual experimental scenario of road intersection risk was designed and constructed, including pedestrian to motor vehicle, non motor vehicle to motor vehicle, and motor vehicle to motor vehicle conflict; Fifteen middle-aged, young, and elderly drivers were recruited for driving simulation experiments, and data on driver behavior and vehicle operation during the driving process were collected. Relevant indicators were selected for analysis of the experiment. The results indicate that elderly drivers generally have longer reaction time and brake pedal travel compared to middle-aged and young drivers in various risk scenarios; In high-risk driving scenarios, the longitudinal acceleration fluctuation of elderly drivers is greater than that of young and middle-aged drivers, with 10 elderly drivers having a collision accident, accounting for 33.3% of all participants. The research results can provide some theoretical basis for traffic safety policy makers to formulate measures to improve the driving safety of elderly drivers. |
