Tactile Walking Surface Indicators has been placed on road to guide directions and to give attentions to the visually impaired. Some of existing Tactile Walking Surface Indicators are, however, low contrast with surrounding road surface. To improve the problem of contrast described above, addition of lateral band to Tactile Walking Surface Indicators has been proposed. The persons with low vision capability sometimes misunderstand long objects on road surface as holes or ditches. As the first stage of the research, visibility of the lateral band of different color and width were experimentally measured by subjects with the persons with low vision capability.
