视觉系统是驾驶员获取行车信息的主要方式,而城市道路景观分布是引起驾驶员视觉刺激性的关键因素之一,为此,需研究城市道路景观分布对驾驶员视觉刺激性的影响.实验路段选择某地省道,对选择路段的景观异质性进行评价.在研究实验样本的基础上,选择6位高校老师作为驾驶员参与实验.将眨眼时间、注视时间、瞳孔直径、扫视幅度作为衡量指标,研究路段1和路段2景观对驾驶员视觉刺激的影响.结果表明,驾驶员在景观相对复杂路段的瞳孔直径和扫视幅度较大,眨眼持续时间与注视持续时间较小;不同城市道路景观对驾驶员的眨眼持续时间、注视持续时间、扫视幅度影响不显著,对驾驶员的瞳孔直径影响显著.%Visual system is the main way to get traffic information of the driver,and the city road landscape is one of the key factors causing distributed,the driver's visual stimulation of this research,city road landscape distri-bution on the driver's visual stimulation effect. The experimental section selects a provincial road,and evaluates the landscape heterogeneity of the selected section. According to the evaluation results,the longitudinal section is 2% and the longitudinal grade is 0%. The section is taken as the object of study. On the basis of the experimental sam-ples,6 college teachers were selected as drivers to participate in the experiment. Blink time, fixation time, pupil diameter,and saccade amplitude were used as indicators to study the effect of 2 landscape in Section 1 and section on visual stimulation. The results show that the driver in the pupil diameter and the saccade amplitude is relatively complex large sections of the landscape,blink duration and gaze duration is small;different city road landscape on the blink of an eye,for driver's fixation duration,saccade amplitude has no significant influence on pupil diameter significantly influence the driver's.
