Signs must give clear directions, information and instructions and mark the exact locations of the facilities provided for persons with a disability. The international symbol of accessibility (a white wheelchair figure on a blue background, proportioned as the figure shows) is displayed at the accessible entrance and exit, the reserved car parking, the accessible toilets, the usable vertical circulation and cloakroom facilities, and where an information or service counter or telephone offers special services; directional arrows and visual information accompany the symbol at conspicuous locations to guide users to the facilities; the later items set the sizes of signs by viewing distance, the sign for persons with hearing impairment (marking assistive listening systems) and the Braille and tactile signs and their positions. The Best Practice Section covers tactile maps and consistent sign systems.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
