The application of tactile ground surface indicators (TGSI'S) on intersections in South Africa

Abstract

Paper presented at the 33rd Annual Southern African Transport Conference 7-10 July 2014 "Leading Transport into the Future", CSIR International Convention Centre, Pretoria, South Africa.

The correct implementation, application as well as construction of pedestrian ramps in South Africa have created much confusion and controversy for the last 9 to 10 years. Not to mention the correct inclusion of Tactile Ground Surface Indicators (TGSI) or Blister paving as some may call it, on pedestrian ramps and intersections. The disputation concerning the matter is largely due to a lack of information available in South Africa (SA), or contradicting information, where bits and pieces are mentioned. To make matters worse, the available information is also outdated to current international standards and requirements. About thirteen (13) integrated rapid public transport networks (IRPTN) are under various stages of planning and implementation in SA. Along these Bus Rapid Transit (BRT) routes, thousands of intersections would be impacted by the projects and need upgrading and redesign to some form or the other. Mostly, all BRT stations would also be in the median at or close to intersections and safe and convenient passage is required to get pedestrians to and on BRT busses. This includes the less able, be it temporary or permanent and people with disabilities. A few years ago (2010), GIBB researched the application of TGSI’s on intersections and developed the Standard Construction Detail and Design Standards for Intersection Pedestrian Crossings affected by the Bus Rapid Transit Infrastructure, incorporating international best practice, in consultation with the Department of Transport, South African Bureau of Standards (SABS), some Universal Access Consultants and some Disability Alliance groups. This paper gives a brief overview of the developed standard book of drawings and shows a few implemented examples in South Africa.
