摘　　要：为了深入研究驾驶员的交通标志视认性,本文从驾驶经验和在驾驶过程中驾驶员是否打电话2个因素进行研究,共招募20位驾驶员,其中10位新手驾驶员和10位有经验的驾驶员,所有驾驶员需要完成打电话和不打电话2种情况下的驾驶任务.利用眼动仪记录驾驶员的眼动数据,主要分析了交通标志牌平均注视持续时间、交通标志牌注视点百分比和平均停留次数3个眼动参数.研究表明:不同经验的驾驶员对交通标志牌的视认性存在显著差异;在打电话和不打电话情况下的驾驶员对交通标志牌的视认性存在显著差异;并且打电话行为,对新手驾驶员交通标志牌的视认性影响显著大于有经验的驾驶员.The present study investigated the influence of driving experience and talking on the phone during driving on driver＇s ability to recognize traffic signs. In the driving simulator experiments,we recruited 20 drivers,including 10 novice drivers and 10 experienced drivers. All drivers were required to complete a driving task in a situation with and without talking on the phone. The eye tracker was used to record the driver＇s eye movement data,including the average fixation duration,traffic signs fixation point percentage and average number of fixation. The results indicated： both driving experience and talking on the phone had a significant effect on driver＇s ability to recognize traffic signs. In addition,the task of talking on the phone had a more significant effect on novice drivers＇ ability to recognize traffic signs,as compared to experienced drivers.
