摘要

随着我国高速公路飞速的发展，怎样保障高速公路高效、安全的运营一直是社会各部门各阶层共同努力的目标。本文首先简单分析了高速公路事故影响因素，并仔细研究国内外交通标志标线设置的研究状况，在此基础上提出国内高速公路标志标线设置现状。本文在提出交通标志标线设置优化建议之前，对交通标志的视认性进行了室内和室外的两个小实验，室内实验是通过三维动画实现标志认读过程的模拟，记录视认时间进行数据分析，得到驾驶员视认距离和行驶速度以及标志版面信息量的一般规律；室外实验是通过设计不同的标志版反光膜组合进行反光膜的视认性研究，通过实验提出最佳的标志牌反光膜组合。通过交通标志视认实验研究后，在高速公路事故成因分析以及国内高速公路标志标线设置存在的问题的基础上提出了高速公路标志标线优化的几点建议。最后，关于本文的研究的结论及发展方向进行了简要讨论。

ABSTRACT

With the rapid development of  freeway, how to ensBl'e safe and efficient Highway operation is a common goal  of all sectors of society．In this  paper, a brief analysis of highway accident influence factors is discussed，then  carefully study the setting of traffic signs and markings at home and abroad，based on  which the current problems of domestic setting of highway signs and markings  are pointed out． In this paper, before  proposing optimizational recommendations，two indoor  and outdoor experiments ale conducted for the visualization of setting  traffic signs．The indoor experiment is  done by simulating the identification of signs in 3D animation, analyzing the  recorded reading time，and finally getting the  general regulation of driver’S  recognition distance，speed and the information  quantity of the traffic sign layout．The outdoor  experiment is to study the recognition of reflection films by designing  different reflection film combination of the sign plate，based on  which proposing the optimal layout．After that，several  suggestions to improve the design of freeway traffic signs and markings are  raised．Finally, reach the conclusion of  the study and briefly concern the direction of this area．

Key Words: influence  factor，the  setting of traffic signs and markings，the recognition experiment，reflection film  of the traffic sign plate，optimized  layout.
