摘　　要：视觉系统是驾驶员获取外界信息最重要的通道.通过实地调查和采用眼动仪进行野外试验,对驾驶员的注视行为进行分析.记录行车过程中随着车速的增加,驾驶员认读标志时注视标志的次数和认读时间的变化,同时记录驾驶员对认读标志的注视持续时间变化.采用BHS6型眼动仪自带的分析程序EyeNalAnalysis Software,对试验原始数据进行初步处理和分析,最后采用SPSS13.0数据分析软件对数据进行统计处理,得出了不同车速对驾驶员认读标志过程中注视行为的影响范围,将为干线公路交通标志牌的设置与改进提供理论依据.Visual system is the most important channel for drivers to obtain the outside information. Through field survey and eye tracking field test driver＇s gaze behavior is analyzed. With vehicle speed increasing, the number of fixation, visual cognition time and fixation duration are recorded. Then EyeNal Analysis Software is applied to process and analyze the raw data. Finally statistical data processing is carried out with SPSS13.0. The influence range of different speeds on gaze behavior during driver recognizing and reading signs are obtained. The research results will provide a theoretical basis for the settings and improvements of trunk road traffic signs.
