高速公路干扰跟车时驾驶人注意力分配特性

Drivers' attention distribution characteristics in cutting-in process on freeway

为探索干扰跟车过程中驾驶人注意力分配规律,引导新手驾驶人合理观察周围车辆,首先利用face LAB 5眼动仪开展高速公路环境中实车试验,采集并记录13位驾驶人的眼动数据。然后分析干扰车从不同车道切入时驾驶人的注意力分配特性,以及驾驶人注意力在各注视区域之间的转移规律。试验数据显示,干扰车切入过程中,驾驶人主要注意力集中在正前方视野,更多地关注与行车安全最相关的动态目标;干扰车切入后,驾驶人对干扰车切入一侧的关注度较高。

In order to explore the influence of interfering car on attention distribution characteristics and guide new drivers to allocate their attention reasonably,real vehicle experiments in a freeway environment were carried out using eye movement instrument face LAB 5. Eye movement data of 13 drivers were collected and recorded. And then,drivers＇ attention distribution characteristics were analyzed when interfering car cutting in from different sides. Besides,drivers＇ fixation transfer rules between different fixation areas were studied. The results show that in the process of interfering car cutting in,the driver mainly focuses on the front view,especially pays more attention to dynamic targets such as front vehicle and interfering car,and that the driver pays more attention to the side where interfering car cutting in.
