摘 要: 通过装有“眼动仪”(SmartEye)的实车进行不同城市道路交通环境下的驾驶实验,对8名不同经验驾驶人的眼动行为差异性进行测试。研究过程中,将驾驶人视觉图像信息分解为意义层、运动层、物理层和景观层4层结构,建立驾驶人视觉层级模型,在此基础上着重分析不同城市道路交通环境对驾驶人的视觉眼动行为产生影响的机理。研究表明:不同的道路交通环境会对驾驶人的水平/垂直搜索范围、平均注视持续时间和平均扫视时间等眼动指标产生影响,对不同驾驶经验的驾驶人来说,受到各因素的影响程度不完全相同。研究成果为创新城市道路交通设计和评价提供技术参考,使得城市道路交通环境可以更好地满足不同经验驾驶人安全舒适驾驶的需求。

Abstract: In this paper, the real vehicle driving tests have been done with “eye tracker” (SmartEye) under different urban environments, which are used to examine eight different driving experience driver’s eye movement behavior differences. The driver’s visual scenes are stratified into meaningful layer, motion layer, physical layer and landscape layer. A driver’s visual scene hierarchical model by these four layers has been established in this study. On this basis, the mechanism of driver’s visual behavior impacted by urban traffic environment has been analyzed. Research shows that the different road traffic environments will affect the driver’s horizontal/vertical search range, average fixation duration time and average saccade eye movement time. The degree of influence of each factor to different driving experience driver is not exactly same. This research provides technical reference to innovative design and evaluation of urban road traffic. It could make the urban road traffic environment better to meet the needs of different people safe and comfortable driving.
Key words: road works; urban road; visual behavior; driver’s visual scene hierarchical model; impact mechanism
