Abstract A detectable warning is a standardized surface feature, comprised of closely spaced surface projections (truncated domes), built in or applied to walking surfaces to warn visibly impaired individuals of hazards. U.S. DOT regulations, under the Americans with Disabilities Act (ADA), require that transit systems place detectable warnings at key transit stations. This report presents the results of a comprehensive testing and performance evaluation program for detectable warning materials placed along the edges of transit station platforms. The report is intended to provide information and guidance to rail transit systems to assist them in the selection and installation of detectable warning systems. The scope of the test and evaluation program included the laboratory testing of 18 detectable warning materials and the subsequent installation of 8 of those materials at indoor and outdoor transit stations in Boston, Cleveland, and Philadelphia. The program evaluated the engineering performance characteristics of the materials with regard to wear, durability, adhesion/bonding to the platform surface, and appearance. A performance assessment of all 8 detectable warning materials and their installation is provided.
