Tactile Indicators are made from various materials installed onto the ground surface consisting of a series of raised Strips and Studs. The purpose of Tactile Ground Surface Indicators (TGSI) is to assist pedestrians who are blind, or who have vision impairment with warning of hazards and directional information to aid navigate the sidewalks of the roads and the sidewalks of Public Buildings.
This is achieved by aligning the raised Strips and Studs pattern of the Tactile Indicators on the ground surface, enabling blind pedestrians to feel the textural changes through their feet or with a cane.
Pedestrians with limited vision use the colour contrast between the Tactile Indicators and ground surface to detect the modules visually.
TGSI are predominantly used to lead pedestrians to and identify public access facilities such as intersection kerb ramps, pedestrian crossings, stairs, lifts, ramps and escalators. They are also used at public transport facilities to alert pedestrians to platform edges at train stations, bus and tram stop areas and ferry wharves.
In addition in assisting with orientation, Tactile Indicators help provide safe, dignified & independent access to and within the community.
