道路交通标志单因素视觉信息易读性研究

文章研究交通标志文字的字数对信息易读性的影响.通过设计实验来测量不同字数的道路交通标志认读阈限,作为衡量视觉信息易读性的一个标准.通过重复测量设计实验,对此实验得出的数据进行单因素重复测量方差分析,得出字数对易读性的影响关系,随着字数的增加易读性越差.为以后设计符合人类工效学原则的道路交通标志工作做铺垫.

This paper studies the influence of the number of words of traffic signs on the readability of information. Through designing experiment, we measure the road traffic sign recognition threshold of different words, which is used as a standard to measure the readability of visual information. Through the repeated measurement design experiment, the single factor repeated measurement variance analysis of the data obtained from this experiment is carried out, and the influence of the number of words on readability is obtained;the worse the readability, the larger the number of words. This lays the groundwork for the design of road traffic signs in accordance with the principles of ergonomics in the future.
