| Research Abstract |
In this study, it was confirmed that the low vision miss-recognized lines on roads as ditches at the specific luminance contrast and width of line. Three results were provided from these experiments. It was observed at first that miss-recognition of lines on road surfaces occurred more frequently according to increment of luminance contrast. Secondly, there were no relations between width and visibility of the lines. Finally, there were no relations between illumination and visibility of the lines. In the ISO23599, to secure the visibility of the Tactile Walking Surface Indicators, the luminance ratio of the lateral band is assumed to be 30%. It was clarified that it was undesirable to exceed luminance ratio 30% by this study.
