Tactile Paving, also called Truncated Domes, Detectable Warnings, Tactile Ground Surface Indicators, Detectable Warning Surfaces, is a system of textured ground surface indicators found on many footpaths, stairs and train station platforms to assist blind and vision impaired pedestrians.
Tactile Warnings provide a distinctive surface pattern of "truncated domes" or cones (which are small domes or cones that have had their tops cut off, or truncated) or "truncated bars" detectable by long cane or underfoot which are used to alert people with vision impairments of their approach to streets and hazardous drop-offs. People who are blind or visually impaired are alerted of impending danger from vehicle impact or a grade change. There is a disagreement in the design community and the community of users if the interior use of these bars represents a tripping hazard.
In the U.S. Tactile Warnings Systems are required by the ADA. The federal government, through studies and guidance provided by advocates and the Access Board now mandates Detectable Warnings in prescribed locations, such as on the surface of pedestrian curb cuts and at the edge of rail platforms. Detectable warnings have been required for the edge of rail platforms in the United States since 1991. Detectable warnings for pedestrian curb cuts were suspended for study in 1994, and became officially required in 2001.
The ADA Accessibility Guidelines (ADAAG) require these warnings on the surface of curb ramps, which remove a tactile cue otherwise provided by curb faces, and at other areas where pedestrian ways blend with vehicular ways. They are also required along the edges of boarding platforms in transit facilities and the perimeter of reflecting pools. The raised pattern of domes also known as Truncated Domes are the preferred design for detectable warning tiles and Pavers.
