摘　　要：以驾驶员的视点变化为研究对象,利用Dikablis智能眼动仪,通过在选取路段进行的实车试验,获取驾驶员在通过无信号控制路段行人过街横道线时的眼动参数与注视行为特性。研究结果表明,驾驶员在通过人行横道时,白天和夜间视点在中心区域的注视时间比分别占到了34%和51%,在右侧区域占到了45.3%和34.7%。从正常路段向人行横道过渡时,白天瞳孔面积的变化率达到44.4%,夜间变化率达到26%。正常路段的瞳孔面积夜间相比白天变化率达到65.3%,人行横道处变化率达到67.4%,与白天相比驾驶员的紧张程度高。Taking the change of driver's viewpoint as the research object,using Dikablis intelligent eye movement instrument,through the real car test in the selected section,the eye movement parameters and gaze behavior characteristics of the driver when passing through the pedestrian crosswalk line without signal control are obtained.The result shows that the fixation time ratio of daytime and night viewpoints in the central area are 34%and 51%,45.3%and 34.7%in the right area,respectively,when the driver passes through the crosswalk,which accounts for 34%and 51%of the fixation time ratio in the central area and 45.3%and 34.7%in the right area,respectively.During the transition from the normal section to the crosswalk,the change rate of pupil area reached 44.4%in daytime and 26%at night.Normal road section compared with night,the change rate of pupil area are 65.3%in daytime and 67.4%in crosswalk,which is higher than that in daytime.
