| 摘 要： | 采取理论分析和大量现场试验相结合的研究方法,分析了指路标志汉字字高与视认性的定量关系.基于视觉生理学理论和非线性回归分析的方法,建立了交通标志汉字字高通用模型,该模型与实测数据之间具有较好的拟合性.研究结果一方面验证了我国现有指路标志字高标准的合理性和科学性,另一方面为交通指路标志字高的科学设计提供了理论依据.

| Abstract: | Combined theoretical analysis with large number of field tests,the quantitative relationship between word height of Chinese characters on traffic guide signs and their visual recognition was analyzed.Based on vision physiological theory and non-linear regression analysis method,a general word height model of Chinese characters of traffic guide signs was established.Compared with correlative domestic models,this model has better-fitting with measured data.On the one hand,the research result validated the rea... |
