Tactile Ground Surface Indicators (TGSI) are designed to provide a tactile surface as both a warning of an impending pedestrian hazard and also as an added safety precaution. They consist of a series of raised studs or bars which can be installed as paving units or individual stud fixed into the ground surface or mats that are glued to the ground. Together the TGSI create a pattern that functions as a navigational indicator for pedestrians.

Here are the different types of tactile indicators and how they should be deployed in order to create safer pathways for pedestrians.

Who Needs TGSI?

TGSI are typically installed for people who are blind or who have vision impairment allowing them to navigate in an urban environment. People who have low vision can make use of the colour contrast between the tactile solution and the ground surface itself to ensure that they navigate the surface safely. They can also be used at public transport facilities to make pedestrians aware of platform edges at train stations, bus and tram stops, as well as ferry wharves.

Types of Tactile Indicators

There are two major types of tactile indicators: warning and directional tactile indicators. Here are the differences between each type:

Warning Tactile Indicators

Warning tactile indicators, also known as hazard tactiles and sometimes decision tactiles. They are installed to walking surfaces in a raised grid pattern. They are are designed to act as a ‘stop’ sign by alerting blind or vision impaired pedestrians to hazards in their line of travel and that they must first stop to determine the nature of the hazard before moving any further. These tactile indicators do not provide any information as to what type of hazard lies ahead.

Directional Tactile Indicators

Directional tactile indicators, also known as leading tactiles, are made up of a series of raised bars that are designed to be installed to the ground surface, in an orientation that is in line with the preferred direction of travel. These tactile indicators are designed to help pedestrians walk along an intended pathway that is free of obstacles, often terminating at a pad of warning tactile indicators.
