摘要
为研究草原公路景观要素复杂程度对驾驶员眼动指标的影响,开展现场试验,选取3种典型景观要素构成路段,测试5名驾驶员的眨眼持续时间、注视持续时间、瞳孔直径和扫视幅度等4个眼动指标。用Be Gaze2.4及SPSS软件提取、分析数据,画出3种景观要素构成与眼动指标的关系曲线,分析其变化规律,并通过主观调查问卷验证分析结果。试验结果表明:随着景观构成要素的增加,眨眼时间不断减小,注视时间也小幅减小,而瞳孔直径和扫视幅度逐渐增加,但变化幅度不大;与景观a和景观c相比,景观b更能增加草原公路行车舒适性,减少消极情绪。
For the sake of studying the influence of the complexity of the landscape elements of grassland highway on the eye movement index of the driver,field tests were carried out,5 participants＇ blink duration,fixation duration,the pupil diameter and scanning amplitude were collected on a grassland highway having three landscapes.The eye movement indices were collected by Be Gaze2.4 and analyzed by SPSS.The relationship between the three landscape elements and the eye movement index was established and the variation law was analyzed.The results of the analysis were verified by a subjective questionnaire survey.The results show that the increase of landscape elements makes both the drivers＇ fixation duration and blink duration reduce,but makes both the pupil diameter and scanning amplitude increase slightly.Compared with the landscape a and c,landscape b can increase more grassland highway driving comfortableness,reduce the negative emotions.
