【摘要】：为提高老龄化背景下道路交通的安全性,基于驾驶模拟试验数据,分析老年驾驶员的跟驰行为特征,并深入研究驾驶员跟驰行为的影响因素。选取车头间距、速度和反应时间作为驾驶员跟驰行为的表征指标,通过对比老年驾驶员与年轻驾驶员跟驰行为的差异,分析老年驾驶员的驾驶特征;进一步采用Pearson相关系数法研究跟驰行为与驾驶员年龄、驾驶负荷和驾驶偏好的关系。研究结果表明:相较于年轻驾驶员,老年驾驶员对前车紧急制动行为的反应时间较长,行驶速度的变化较大,且保持较大的车头间距。驾驶员的跟驰行为与年龄、驾驶负荷得分以及驾驶偏好显著相关。
[Abstract]:In order to improve the safety of road traffic under the background of aging, based on the driving simulation test data, this paper analyzes the characteristics of the driver's car-following behavior, and deeply studies the influencing factors of the driver's car-following behavior. Choosing the headspace, speed and reaction time as the indicator of driver's car-following behavior, the characteristics of the elderly driver were analyzed by comparing the difference between the aged driver and the young driver. Pearson correlation coefficient method was used to study the relationship between car-following behavior and driver's age, driving load and driving preference. The results show that compared with the young drivers, the older drivers have longer reaction time, greater variation in speed and larger head-spacing for the emergency braking behavior of the front car. Driver's car-following behavior was significantly correlated with age, driving load score and driving preference.
