Truncated Dome Spacing
One of the issues that has arisen with detectable warning tiles is the truncated dome spacing. Tactile warning systems have been required in the United States ever since the Americans with Disabilities Act (ADA) passed in the early 1990’s. Tactile warnings are required in locations such as pedestrian curb cuts and transit platforms. The detectable warnings provide a tactile clue to blind or visually impaired individuals that they are about enter into an area shared with vehicular traffic. The tactile warnings consist of domes with flat heads (hence the term ‘truncated’).
One of the issues with tactile warning systems has been the truncated dome spacing. An inline or grid design ultimately proved to be more practical for truncated dome spacing, as wheelchairs and strollers had difficulty traveling over alternating dome patterns.
Another issue with truncated dome spacing has been the distance between the domes. Initially, tactile warning systems featured a spacing of 1.67 inches between domes. However, even this width made accessibility difficult for wheelchairs and strollers. More recently, several U.S. municipalities have adopted a wider truncated dome spacing of 2.35 inches.
All of the detectable warning tiles in the Access Tile line feature the new wider 2.35 inch truncated dome spacing. The surface of all Access Tile products is designed for superior anti-slip properties. The area between the truncated dome spacing features a ‘pyramid with sides’ design that will wear better than other designs. The tops of the domes also feature twice as many tactile elements on the surface compared to other products currently available.
Access Tile is the right choice for the best in truncated dome spacing, anti-slip protection, and affordability.
