交通标志汉字视认性的研究

The Identification of the Chinese Characters in Traffic Signs

本文论述了影响交通标志中汉字认读的一些主要因素:汉字字体、高宽比、笔画数、字频、字间距及行间距等;提出了利用标准视标E与汉字两者认读之间的相互转换关系来计算标志中汉字的字高公式;通过测定认读时间来确定最小认读距离,为高速公路交通标志中的汉字设计提供理论依据.

Some primary factors affecting the identification of the Chinese character in traffic signs,such as:the style of Chinese character,the height to-width ratio of characters,the number of strokes ,the utilization frequency,space between characters,a row spacing and so on are described in the article. A formula is proposed to calculate the height of Chinese characters in the traffic signs by means of the correlation between the identification of standard visual target chart E and the identification of Chinese character ;the minimum distance of identification is also determined by the measurement of the minimum identification time. The results will provide a the oretical basis for the design of freeway traffic signs with Chinese Characters.
