| 摘要： | The Americans with Disabilities Act mandates the use of tactile detectable warning systems at curb ramps to warn the blind and visually impaired of the transition to a vehicular way. The Americans with Disabilities Act Accessibility Guidelines outlines geometric, dome shape and visual contrast guidelines for detectable warning systems, which are generally adopted into federal, state and local requirements. Detectable warning systems meeting these requirements are currently available in a broad range of materials and designs, and the anticipated long-term performance of these systems varies widely. Little information is available regarding the long-term durability of many detectable warning systems currently on the market. The durability of these systems is an important part of their performance. / Supplementary Notes: Sponsored by Transportation Research Board, Washington, DC. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
