中文摘要：

为提高安全标志有效性,需要对安全标志五维特征与标志识别率关系进行研究。选取50名安徽工程大学在校学生为试验对象,40个禁止安全标志为试验材料,研究安全标志的五维特征与标志识别率的关系,建立安全标志识别率与标志五维特征的多元线性回归方程模型。结果表明：标志的熟悉性对标志识别率影响最大,其后依次为简明性、具体性、语义相关性、明确性。此外,回归模型中,常数项为正值,说明仍有其他因素影响标志识别率,有待进一步研究发现。

英文摘要：

In order to improve safety signs’ effectiveness, the relationship of safety sign recognition rate and five sign features should be studied. To perform the experiments, 50 college students from Anhui Polytechnic University were selected as subjects, 40 prohibition signs used in the experimental. We establish a multiple linear regression equation model based on the relationship of safety sign recognition rate and five sign features. The results show that the familiarity of safety sign has the most significant impact on the recognition rate, followed by simplicity, concreteness, semantic closeness, meaningfulness. In addition, the constant term is positive in the regression model which indicates that there are some other factors affect sign recognition rates. It is necessary that the influencing factors of safety signs’ effectiveness should be studied in further research.
