摘要:: 为研究在不同路况下驾驶员的视线变化情况，本研究利用SMI iView XTM RED遥测眼动追踪装置，采用虚拟驾驶软件，模拟晴天、雨天和夜晚环境下城市、乡村及高速道路的驾驶，展示和分析了驾驶员在不同道路环境下眼动注视时间与次数，回视次数和热点图。结果表明：相同道路下，光线越差，驾驶人注视点数和回视点数越多；速度越快，视野范围越窄。本研究为深入研究驾驶人的视觉行为规律、提高驾驶人行车安全性提供一定的试验基础。

Abstract:: In order to study the drivers’ visual changes in the different road conditions, the SMI iView XTM RED was used to measure eye movements. With virtual driving software，the participants drove on the different roads(city, village and high speed road) in sunny, rainy and night environment, the data about fixation duration, fixation times, regressive times and hot maps were presented and analyzed. The results show that the worse the light is, the more drivers’ fixation times and regressive times are; the faster the speed is, the narrower the scope is. We provide the experimental basis for studying the rules of eye movements and drivers’ driving safety under different environmental conditions.
