Detectable Warnings Info
Detectable warnings are intended to function much like a stop sign and to alert pedestrians who are visually impaired to the presence of a hazard in the line of travel.
A Detectable Warning surface is defined by ADA Accessibility Guidelines (ADAAG) as “a standardized surface feature built in or applied to walking surfaces or other elements to warn visually impaired people of hazards on a circulation path”. Detectable Warnings incorporating truncated domes are the best indicator to alert pedestrians there is a hazard approaching in their way of travel. Truncated domes are the only detectable warnings allowed by ADA Accessibility Guidelines (ADAAG).
Due to their distinctive design, truncated domes can be identified under foot and by sound on cane contact. Color contrast is another beneficial aspect of the truncated dome, making the tile visually detectable from the surrounding surface.
Armor-Tile offers detectable warning systems for curb ramps, vehicular ways, parking areas, stairwells, pedestrian crossings, escalator approaches, transit platforms and multi-modal transit.
