摘要
为改善指路标志信息量过载评价方法和弥补规范相关指标不足问题,文章提出采用汉字个数和路名数作为指路标志信息量评价指标。通过设计室内指路标志视认实验,采用稳健估计理论和95%分位值方法对实验数据进行处理。分析结论得到不同行车环境下指路标志的极限汉字个数和路名数阈值模型。研究成果可作为指路标志信息设计的参考依据,在提高指路标志视认性和行车安全方面具有重要意义。
In order to improve the ability of information evaluation method in guide signs, the number of Chinese characters and road names were proposed to evaluate the guide sign information. For guide signs with different .height of Chinese characters in different design speed road, Equations for threshold number of Chinese characters and road names were conduced by indoor guide signs recognize experiments and theoretical analysis, which helps designer to bring more flexible productions.
