TACTILE GROUND SURFACE INDICATORS (TGSI's)

Approximately 330,000 are blind or vision impaired and many more have some reduction in the effectiveness of their sight. Application of Tactile Ground Surface Indicators with the built environment enhance the safety, dignity and independence with which people who are blind or vision impaired have access to the built environment.

WHAT IS A TACTILE GROUND SURFACE INDICATOR?

Tactile Ground Surface Indicators are truncated cones and/or bars installed on the floor surface, designed to provide pedestrians who are blind or vision impaired with warning or directional information.

 

TGSI's may be required in the following situations:

 

- Stairways

- Ramps (other than threshold ramps)

- Escalators

- Level and inclined moving walkways

- Overhead Hazards

- Carriageways

 

There are 3 types of TGSI's that may be used to satisfy these requirements:

INTEGRATED TGSI's

DISCRETE TGSI's

DISCRETE TGSI's

MULTIPLE COLOUR/MATERIAL

Where TGSI's are used, there is also a requirement for a minimum luminance contrast to be achieved. The minimum luminance contrast will differ depending on the type of TGSI.

 

Integrated TGSI's require 30% minimum luminance contrast between TGSI and base surface.

 

Discrete TGSI's require 45% minimum luminance contrast between TGSI and base surface.

 

Multiple colour/material TGSI's require 60% minimum luminance contrast between the raised surface (diameter of 24-25mm) and the base surface.

If you require further information regarding TGSI's, please contact your local sales representative.
