道路环境对驾驶人眼动行为影响的试验研究

为了分析道路类型条件对驾驶人眼动行为的影响，分别在城市道路、城乡结合道路及山区公路上开展试验，利用EyeLink Ⅱ型眼动仪对20 名驾驶人的眼动行为进行测试和记录，分析不同道路环境中驾驶人的注视区域、注视目标及注视时长等特征.结果表明，驾驶人根据道路环境的变化调整其视觉搜索行为，在交通环境相对简单的道路上，驾驶人注视较远且平均注视时间较短，而在交通环境复杂多变的道路上，驾驶人注视较近且平均注视时间较长.研究结果为深入研究驾驶人的视觉行为规律、提高驾驶人行车安全性奠定了试验基础.

Impact of Road Conditions on Car Drivers Fixation Behavior with On-road Vehicle Tests

To analyze the impacts of road conditions on car driver’s fixation behavior, 20 drivers’eye movement data and fixation behaviors are tested and recorded by EyeLink Ⅱ eye movement tracker in the condition of driving on urban roads, suburban roads and mountainous highways. Drivers’fixation behavior characteristics in different types of road conditions are studied. The results indicate that, drivers adjust their visual search behavior according to the changes of road environment. When driving in relatively simple road traffic environment, drivers watch farther and the mean fixation duration is shorter, while in complex environment, drivers watch closer and the mean fixation duration is longer. The findings laid experimental basis for in-depth study of driver visual behavior laws and traffic safety.
