This 1995 image depicted a visually-impaired man with a walking stick who was approaching the opened electronic doorway of a high-speed trai
This 1995 image depicted a visually-impaired man with a walking stick who was approaching the opened electronic doorway of a high-speed train from a platform, the edge of which was surfaced with a high contrast, enhanced-tactile yellow covering. A transit/subway platform with a yellow detectable warning strip assists people with visual impairments from inadvertently walking into hazardous vehicular routes. The tactile difference between the warning strip and the adjacent surface is a good textural cue underfoot, while also producing an auditory distinction when a long cane user taps from one surface then the other. The contrast and tactile distinction are valuable for sighted users also.
