青少年司机在机动车事故中所占比例过高，大多数研究认为这主要是由于他们缺乏经验和冒险倾向。先进驾驶辅助系统（ADAS）的设计旨在为驾驶过程中的人类信息处理提供多个阶段的帮助，包括环境感知、信息处理、决策和车辆控制，以提高驾驶安全性。预计新手驾驶员可能比成年驾驶员从使用ADAS中受益更多，因为这些技术可以弥补他们频繁的错误。本研究通过对两个独特的自然驾驶研究数据集的分析，研究了集成的碰撞警告系统是否以及如何影响驾驶员的跟随行为，以及相应的年龄相关差异。结果表明，ADAS对青少年驾驶员的跟车行为有潜在的负面影响，青少年驾驶员在使用ADAS的治疗周内对踏板使用的控制程度往往低于未使用ADAS的基线周，而成年驾驶员则没有观察到这种行为。所有成年驾驶员在夜间驾驶时倾向于保持比白天更长的车头时距，以补偿视力差的情况，但在青少年中没有观察到这种补偿行为。此外，青少年和半成年驾驶员比中年和老年驾驶员有更积极的跟随行为（平均车头时距更短）。这项研究的一个局限性是，这项研究的结果只是解决ADAS暴露的短期影响，需要未来的研究来检查纵向影响。这项研究的结果表明，未来ADAS的设计应考虑尽量减少对青少年驾驶行为的潜在负面影响。
Teen drivers are overrepresented in motor vehicle crashes, and most studies concluded it was mainly due to their lack of experiences and tendencies of risk-taking. The design of advanced driving assistance systems (ADAS) aims to provide assistance in multiple stages in human information processing during driving, including environmental sensing, information processing, decision making, and vehicle controlling, in order to improve driving safety. It is expected that novice drivers may benefit more from using ADAS than adult drivers as such technologies can compensate for their frequent errors. This study examined whether and how an integrated crash warning system impacted on drivers' following behavior, and what were the corresponding age-related differences through an analysis of two unique naturalistic driving study datasets. Significant age-related differences in car-following behavior were found. Results showed potential negative effects of ADAS on teen drivers' following behavior that teen drivers tended to have less controlled pedal use during treatment weeks with ADAS than during baseline weeks without ADAS, while such behavior was not observed in adult drivers. All adult drivers tended to keep longer headways when driving at night than during daytime to compensate for poor vision conditions, but no such compensation behavior was observed in the teens. In addition, teen and young-adult drivers had more aggressive following behavior (with shorter mean time headway) than middle-aged and older drivers. One limitation of this study is that the findings of this study are only addressing the short-term effect of ADAS exposure, and future studies are needed to examine the longitudinal effect. The findings of this study suggest that the design of future ADAS should consider minimizing potential negative impacts on teen driver behavior.
