| 中文摘要: |
| 快速老龄化要求城市公共空间标识提高可读性,这有利于实现全民健康老龄化。基于通用设计原则,结合白内障视觉特征,对成都和重庆两地地铁换乘站标识进行实地调查,并采用蒙塞尔色彩系统测量图形与背景颜色的亮度差。以亮度差ΔL≥6为可读性阈值,重庆站点达标率为46%,显著高于成都的5%；图形与背景常见黑、白、灰组合,颜色对比较弱,识别性较低。研究结果为建立城市公共空间色彩指引提供了量化依据,提出应在导向标识色彩设计中充分考虑老年白内障群体的视觉特征。 |
| 英文摘要: |
| The rapid aging of the population necessitates improved readability of signage in urban public spaces, contributing to the goal of healthy aging for all. Guided by universal design principles and the visual characteristics associated with cataracts, this study conducted on-site investigations of metro transfer station signage in Chengdu and Chongqing. The Munsell color system was employed to measure the luminance contrast between graphic elements and background colors. Using a luminance difference threshold of ΔL ≥ 6 as the criterion for readability, the compliance rate in Chongqing reached 46%, significantly higher than Chengdu’s 5%. Common color combinations—black, white, and gray—were found to offer weak contrast, resulting in low legibility. These findings provide a quantitative foundation for developing urban public space color guidelines and underscore the importance of incorporating the visual needs of elderly individuals with cataracts into the design of wayfinding signage. |
