Tactile ground surface indicators (TGSI) play a crucial role in assisting visually impaired individuals to navigate public spaces safely. When selecting the right tactile indicators for different environments, it’s essential to consider various factors to ensure they meet the specific needs of the environment and the end-users.

Types of Tactile Indicators

Tactile indicators can be broadly categorised into warning and directional tactiles. Warning tactile indicators alert pedestrians of potential hazards, such as stairs, ramps, and escalators, while directional tactiles provide guidance and orientation for visually impaired individuals.

Considerations for Selection

When choosing tactile indicators, several factors should be considered to ensure they are suitable for different environments and meet the needs of the users. Some key considerations include:

• Material and Durability: Tactile indicators are available in various materials such as solid brass, stainless steel, aluminum, polyurethane, and ceramic. Each material offers different levels of durability and aesthetic appeal, making them suitable for different environments.
• Color and Visibility: The color of tactile indicators is crucial for visibility. For instance, yellow tactile indicators are effective for transition areas near stairs or ramps due to their high visibility, while warning tactile tiles are often available in yellow or black to alert pedestrians of potential dangers.
• Dimensions: The dimensions of tactile indicator plates are important to ensure they comply with Australian product selection and installation standards. The size and shape of the tactiles should be suitable for the specific environment and the intended purpose.
