Tactile Ground Surface Indicators
Tactile Ground Surface Indicators (TGSI) are essential accessibility solutions designed to assist visually impaired and blind individuals in navigating public and commercial environments safely. Installed on walkways, platforms, stair approaches, and pedestrian crossings, these textured surface systems provide tactile and visual cues that communicate warnings or directional guidance.

By creating detectable patterns underfoot, tactile indicators help users identify potential hazards such as platform edges, road crossings, level changes, or obstacles. They play a critical role in inclusive design strategies and support compliance with accessibility regulations in many countries.
There are generally two primary types of tactile ground surface indicators. Warning indicators, often featuring truncated dome patterns, alert users to hazards or decision points ahead. Directional indicators, typically composed of raised bars, guide users along a safe path of travel through open spaces such as train stations, public squares, and building entrances.
Manufactured from durable materials such as stainless steel, polyurethane, rubber, or composite polymers, tactile indicators are built to withstand heavy pedestrian traffic and environmental exposure. Anti-slip properties enhance safety in wet conditions, while high-contrast color options improve visibility for partially sighted users.
Tactile ground systems can be surface-mounted for retrofit applications or integrated directly into new flooring during construction. Modular tiles and individual studs allow flexible installation according to site-specific accessibility requirements.
Beyond regulatory compliance, tactile ground surface indicators demonstrate a commitment to universal access and social responsibility. They improve independence, confidence, and safety for users with visual impairments while enhancing overall pedestrian navigation.
Implementing professional Tactile Ground Surface Indicators ensures safer public environments, better wayfinding, and inclusive infrastructure designed to accommodate all members of the community.
