ADA is the American Disabilities Act relating to issues of access and in particular, stairs, doors, sidewalks, and ramps, as well as relevant material changes of elevation, direction, surface and any edges or borders with inherent dangers such as the entrance to an elevator or flat sidewalk that transitions into a vehicular path or parking lot. It's also the reason you now find many office hallway signs with labels in braille.
