摘　　要：为提高驾驶员在夜间快速路分流区换道的安全性,以不同风格的驾驶员为研究对象,分析不同风格驾驶员换道时眼动参数的变化规律。首先在前人研究基础上自编夜间快速路驾驶风格量表,对量表进行信度和Pearson相关系数法的效度检验;然后通过主成分分析法对问卷调查法得出的结果进行分析,得出驾驶风格综合得分量化模型,并使用K均值聚类分析法划分驾驶风格;最后基于眼动仪进行实车试验,获取三种风格驾驶员换道的眼动数据。试验结果表明:谨慎型、一般型、激进型驾驶员对于后视镜平均注视次数占比为48%、27%、25%;对左右两侧的平均累计注视时间占比是31%、25%、19%;平均瞳孔面积占比为56.3%、27.6%、16.1%。试验结果可以为提高驾驶员换道的行车安全性研究提供一定的数据支持。In order to improve the safety of drivers changing lanes in the nighttime expressway diversion area,this paper took different styles of drivers as the research object,and analysed the problem of the change pattern of eye-movement parameters of different styles of drivers when changing lanes.This paper firstly compiled its own nighttime expressway driving style scale based on previous research,and then carried out validity tests on the scale by means of reliability and Pearson correlation coefficient method.The eye-movement data of the three styles of drivers were obtained.The test results show that the average number of times cautious,average and aggressive drivers look into the rearview mirror is 48%,27%and 25%,the average cumulative gaze time on the left and right sides is 31%,25%and 19%,and the average pupil area is 56.3%,27.6%and 16.1%;the test results can provide some support for the study of improving the driving safety of drivers changing lanes.
