【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。
[Abstract]:In order to study the influence of the complexity of landscape elements of grassland highway on driver's eye movement index, a field experiment was carried out. Three typical landscape elements were selected to form a road section, and the blinking duration and fixation duration of 5 drivers were tested. Pupil diameter and acuity were 4 eye movement indexes. By using be Gaze2.4 and SPSS software, the data were analyzed, and the relationship curves between the composition of three landscape elements and eye movement index were drawn, and the law of change was analyzed, and the results were verified by subjective questionnaire. The results showed that with the increase of landscape components, the blinking time and fixation time decreased, while the pupil diameter and acuity increased gradually, but the changes were not significant, and compared with landscape a and landscape c, the blinking time and fixation time decreased slightly. Landscape b can increase the ride comfort of grassland highway and reduce negative emotion.
