道路交通警告标志图形认知与改善设计

Research of Perception and Improvement Design in Warning Traffic Sign Symbols

以警告标志为研究对象,通过问卷调查,根据数据统计,运用单因素方差分析的方法分析了受测者的年龄、性别、学历等因素对警告标志认知无显著影响,并对低于67%的认识率的警告标志,以语意分析方法从"名称含义不清楚""不易识别""不易联想""图形设计太复杂"4个因子进行辨识错误分析,并进行了优化改善设计,通过方案必选和认识率的研究,最终确定合理的改进警告标志.

Warning sign is an important component of traffic signs, which can be make road users notice the potential dangers, and reasonable warning sign can improve road efficiency and safety. With the increase of vehicles numbers, traffic environment and traffic behavior of road users becoming more and more complex, traffic sign symbols must be simple and clear to finish visual communication efficiently. The paper takes warning sign as the research object, through the investigation by questionnaire and the data analysis by the one-way ANOVA,the results showed different age, gender, and education background have no obvious influence on the perception of warning sign. For less than 67% perception of warning signs, using semantic analysis method, the perception errors are researched by the four factors, which are unclear meaning, uneasy recognition, uneasy association, and complex symbol design, and optimization design of the warning signs are improved. At last, through scheme comparison and the perception of warning signs, reasonable and improved warning signs are determined to better play management and service functions.
