摘　　要：为深入探讨交通工程设施对高速公路行车安全性影响,本文从高速公路上交通工程设施设置前后驾驶人动态视觉特性指标的差异性角度展开研究,采用数理统计与回归分析方法,对交通工程设施设置前后测试采集的数据进行了对比分析,定量研究了高速公路上交通工程设施设置前后的驾驶人的注视及扫视等变化的影响。试验结果显示,高速公路行车过程中车速、视野、注视点距离之间显著相关,并得到随着车速增加受到信息刺激次数及反应错误次数也随之增加;交通工程设施设置前后对驾驶人的各项视觉特性指标存在明显影响。In order to discuss the effect of traffic engineering facilities on highway traffic safety, this study develops from the angle of the difference of driver dynamic visual characteristic parameters before and after the setting of traffic engineering facilities on freeway. The method of mathematical statistics and regression analysis are adopted to compare the data collected before and after setting the traffic engineering facilities. The influence of the change of driver＇s gazing and scanning before and after setting the traffic engineering facilities are studied. Experimental results show that in the process of highway traffic, the speed, vision, fixation point distance has significant correlation. And with the increase of speed, the times of information simulation and response error increase too. There is significant influence on driver＇ s various visual characteristics of indicators after setting traffic engineering facilities on freeway.
