利用利用眼动仪系统,以城市道路隧道路段驾驶员注视点变动为研究对象,对4名驾驶员共进行16次有效行车试验,得出注视点分布一般特征.并根据心理学研究中提出的视力角概念,用成功扫视幅度中值来量度视力角,建立基于视力角特征的城市隧道标志视认模型:城市隧道行车过程中,当目标物体在注视点分布椭圆边界的视力角范围之内,较容易视认,超过此范围,则难以视认.再利用该模型,对隧道进口交通标志的设置进行安全性评价,并提出改善建议.

Taken driver's eye fixation movement characteristics in urban tunnel as research object,16 times effective driving test were carried out with 4 drivers by using eye tracker system to obtain the universal pattern of eye fixation distribution. According to the psychological concept of the visual lobe,the visual lobe was measured by the median successful saccade size in 2D visual search,and the legibility model of urban tunnel signs based on the visual lobe was established. When the target object is in the range of the visual lobe from the elliptic border of eye fixation distribution,the target object is easy to be cognized,otherwise it is difficult to be cognized. Then the model was used to evaluate the safety of traffic signs,and the improving measures were suggested for reference.
