Abstract

Driver distraction has been identified as an important driving safety issue. However, existed studies focused less on low-speed condition, especially at intersections. This paper aims to find the impact of driver cognitive distraction on vehicle performance at stop-controlled intersections. Eight subjects (young adult: 4, older adult: 4) participated in this study and each of them drove through 40 stop-controlled intersections. The intersections were presented randomly at two levels of FOV (field of view). Driver cognitive distraction was induced by a one-back task and a clock task. Results showed that the cognitive tasks led to more abrupt steering in both age groups while significant influence on lane-keeping capability was only observed in the young group. Steering smoothness was mainly influenced by the cognitive tasks at brake on-restart phase in the young group while at after-restart phase in the older group. Impaired longitudinal control (stop for watching) was observed in the older adult group. These findings can be applied to automatically recognize driver distraction at stop-controlled intersections in future.

驾驶员认知分心对停车控制交叉口车辆性能的影响

驾驶员注意力分散已被确定为一个重要的驾驶安全问题。然而，现有的研究较少关注低速工况，特别是交叉口的低速工况。本文旨在研究驾驶员认知分心对停车控制交叉口车辆性能的影响。8名受试者(青年4名，老年人4名)参加了本研究，每人开车经过40个停车控制十字路口。十字路口在视场的两个水平上随机呈现。驾驶员认知分心是由一个回调任务和一个时钟任务引起的。结果表明，认知任务在两个年龄组中都导致了突发性转向，而对车道保持能力的显著影响仅在年轻组中观察到。青年组的转向平稳性主要受制动启动阶段认知任务的影响，而老年组的转向平稳性主要受制动启动后阶段认知任务的影响。在老年人组中观察到纵向控制功能受损(停止观看)。这些研究结果可以应用于未来在停车控制路口自动识别驾驶员分心。
