Why Have Truncated Domes Become So Much More Visible Recently?A Brief Timeline for Truncated Domes
1991: Detectable Warning Surfaces were first required with the release of the Americans with Disabilities Act Accessibility Guidelines. Detectable Warnings were required on hazardous vehicle ways, transit platform edges, and curb ramps.
1994-2001: A suspension was placed on the requirements with the exception of transit platforms so that research could be conducted on the detectability of the varying tactile surfaces such as grooves, striations, and exposed aggregate. When completed, the research determined that those surfaces were in fact not detectable due to the similarities to normal surface defects found on sidewalks and roadways.
July 26th, 2001: The suspension regarding tactile warnings was allowed to expire and truncated dome detectable warnings specified in the ADAAG were again required.
2001-Present: Truncated Domes are an Americans with Disabilities Act (ADA) requirement in the current Americans with Disabilities Act Accessibility Guidelines (ADAAG) for the use of detecting the boundary between the sidewalk and the street. Truncated domes are the only detectable warnings allowed by ADAAG. Grooves, exposed aggregate, and other designs intended for use as detectable warning are too similar to pavement textures, cracks and joints and are not considered equivalent facilitation. Truncated domes are a unique design and have proven to be the most detectable surface.
