摘要
驾驶员的眼动特征能很好地表现视觉信息加工过程,可通过对高速公路隧道路段驾驶员注视点变动特征的记录及分析来判定隧道环境的安全性和舒适性。运用IView X HED Laptop眼动仪系统,以高速公路隧道驾驶员的注视点变动为研究对象,选取浙江省上三高速公路4座典型隧道,对2名驾驶员分别进行16次有效行车试验,得出驾驶员白天及夜间注视点分布范围。统计表明:在隧道路段,驾驶员注视点在车辆前方0.604～2.557s,夜间注视点分布比白天更靠近车辆前方。并提出交通信号系统改善方法。
Driver＇s fixation Characteristics can express visual information processing course.The record and analysis of driver＇s moving fixation in freeway tunnel can be used to evaluate comfort and safety of tunnel environment.By using IViewX HED Laptop eye tracker system,driver＇s variety of fixation in freeway tunnel was selected as research object,4 freeway tunnels in Zhejiang province were selected,and 16 experiments were carried out for 2 drivers.The fixation distribution was obtained in tunnel stage daytime and night,and the statistics indicated the driver＇s fixation distribution range was between 0.604s and 2.557s from the vehicle head,and driver＇s fixation distribution range in daytime was closer to the vihcle head than in night.The improvement methods were presented to raise the environment safety.
