摘　　要：目的为深度解析城市道路信号交叉口行人过街时视觉搜索特性。方法招募81名行人研究其自由过街状态(FCS)与心理临界过街状态(PCCS)下的眼动行为。基于兴趣区域图分别研究不同过街状态、性别和年龄因素对行人注视点分布、注视次数百分比以及扫视时间百分比的影响。结果女性比男性过街更容易分心,老年行人过街时最谨慎;PCCS下行人对车行区域和信号灯区域的注视次数百分比显著大于FCS;PCCS下老年行人对车行区域关注度更高,少年对其关注度最低;FCS下,男性对车行区域关注度比女性更高;PCCS下行人视觉搜索更频繁;老年视觉转移能力最弱。结论本研究结果对交叉口安全警示标志的布置以及行人过街规则的制订有重要参考意义。Objective In order to analyze in depth the visual search characteristics of pedestrians crossing at signalized intersections of urban roads.Methods 81 pedestrians were recruited to study their eye movements in the free crossing state(FCS)and the psychological critical crossing state(PCCS).Based on the area of interest map,the effects of different crossing states,gender and age factors on the distribution of fixation point distribution,the fixation percentage,and the percentage of saccade time were studied respectively.Results Women are more likely distracted than men when crossing the street,and elderly pedestrians are the most cautious;in PCCS,the percentage of pedestrians gaze frequency in the car area and the signal area is significantly higher than that in FCS;in PCCS,the elderly pedestrians pay the most attention to the car area,while the young pedestrians pay the least;in FCS,men pay more attention to the car area than women significantly;in PCCS,people visually search more frequently;the elderly have the weakest visual transfer ability.Conclusion The results of this study have important reference significance for the layout of intersection safety warning signs and the formulation of pedestrian crossing rules.
