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 aging background, based on a driving simulator, the car following behavior of older drivers and the influencing factors were investigated. Headway, speed and response time were selected as the indexes of car following behavior. Difference in the car following behavior between older and younger drivers was analyzed, and then Pearson correlation coefficient method was used to analyze the relationships among the car following behavior, drivers' age, work load and drivers' preference. The results show that compared with younger drivers, older drivers' time to responding to the emergency brake is longer, and they always adopt the larger headway and are more variable in their speed, and that the car following behavior is significantly related to drivers' age, work load and drivers' preference.

Key words: older drivers, driving simulation, car following behavior, difference analysis, correlation analysis
