【摘要】：为研究城市快速路驾驶人注意力分配特征变化,利用Dikablis眼动追踪系统在某城市快速路4.3 km长路段上开展实车试验,监控并记录9名驾驶人在不同路段环境下的眼动行为。将驾驶人重点视觉域划分为主视区、左后视镜、右后视镜、内后视镜、仪表盘等5个兴趣区域(AOI),分析3个眼动指标在5个AOI内的分布情况。结果显示,不同路段环境下驾驶人注意力分配策略变化受外界环境需要及外部动机显著影响。换道次数增加即受外部动机的影响程度增大,会造成注意力焦点切换的频度增加,注意力分散易引发交通事故;而各AOI的注视点平均注视时间随着车速的增加而减少,可见在复杂环境中行驶应适当降低车速,以保证分配在各AOI注视点的平均注视时间足够进行复杂的信息处理。
[Abstract]:In order to study the change of attention distribution characteristics of urban expressway drivers, a real vehicle test was carried out on 4.3 km long section of an urban expressway by using Dikablis eye movement tracking system. To monitor and record the eye movement behavior of 9 drivers under different road conditions. The key visual domain of the driver was divided into main view area, left rear view mirror, right rear view mirror and internal rearview mirror. The distribution of three eye movement indexes in 5 AOI was analyzed. The change of attention allocation strategy in different road environment is significantly affected by the external environment and external motivation. The increase of the frequency of change of lane is affected by the degree of external motivation. It will increase the frequency of attention focus switching and lead to traffic accidents. However, the average fixation time of the AOI decreased with the increase of the speed, so the speed should be reduced properly in the complex environment. To ensure that the average fixation time allocated at each AOI fixation point is sufficient for complex information processing.
