Tactile Ground Surface Indicators (TGSI) are pavement blocks with small extrusions or raised tactile nodules with an embossed profile that translates into information and guidance to the visually impaired, underfoot or by using a cane. Over the last ten years or so, a lot of controversy and confusion was created about the correct design and construction of tactile pedestrian ramps at intersections in South Africa. After researching local and international documents, reports, guidelines and standards GIBB, developed a standard book on the contemporary standard or guidelines with the City of Tshwane. The document complies and incorporates international best practice, consultation with the National Department of Transport (NDoT), South African Bureau of Standards (SABS), Universal Access Consultants and some disability alliance groups including South African National Council for the Blind (SANCB). This paper gives a brief overview of the developed standard book of drawings and shows a few implemented examples in South Africa and Nigeria.
