摘　　要：利用眼动仪系统纪录分析了在不同车速条件下车辆通过不同字高的交通标志牌时驾驶员眼睛注视点和注视时间的分布规律。结果表明车速和交通标志牌字体高度对驾驶员判读标志信息的过程产生较大影响:在接近标志牌的过程中,随着车速的增加,驾驶员眼睛注视点的几何中心向标志牌偏移,注视范围变小,视线变的更加集中,注视时间也随着车速的增加而延长;在一定车速条件下,当字体较小的时候,驾驶员注视点较集中,判读标志信息的时间较长,随着字体变大,驾驶员注视点越分散,视认性越好,判读时间缩短。With the eye tracker,the eye fixation and fixation time distribution in different speeds are analyzed when the car passes through traffic signs with different font height.The results showed that the process that driver understood sign's information severely affected by speed and font height:when the car neared the sign,with the speed increased,driver geometric center of the eye fixation shifted to the signs,watching range decreased,sight became more concentrated,and fixation time increased with the extension speed;with the condition of fixed speed,when the font height issmaller,driver's fixation became more decentralized,the fixation time of interpretation signs information became longer;with the font height increased,driver had good legibility,and fixation became more dispersion,and fixation time decreased.
