Create Safe Passage on Shared-Use Paths with Tactile Directional Indicators
Tactile Directional Indicators (TDIs), also known as Directional Guidance Indicators (DGIs), are ADA-compliant wayfinding tiles designed to support safe navigation for people with low vision. Featuring raised directional bars, they are ideal for shared-use pedestrian and bicycle pathways and other high-traffic environments. Constructed from durable G90 galvanized steel and engineered to ISO 23599 standards, our indicators withstand heavy pedestrian traffic, wheelchairs, non-motorized equipment, and harsh weather conditions. The lowest-profile edge in the industry minimizes trip risk, while the unique multi-bar system allows for quick and easy field modifications.

FAQs About Tactile Directional Indicators
Tactile directional indicators (TDIs) provide tactile wayfinding cues that help people who are blind or have low vision identify and follow a designated pedestrian route. TufTile TDIs use raised directional bars that can be detected underfoot or with a mobility cane.
TDIs are especially useful in open or complex pedestrian environments where other directional cues, such as walls, curbs, or defined pathway edges, are limited.
Tactile directional indicators provide directional guidance, while detectable warning surfaces provide hazard warnings. TDIs use raised bars to establish a path of travel, while detectable warning surfaces use truncated domes to alert pedestrians who are blind or have low vision to designated hazards or transitions.
The two systems can be used together as part of an accessible pedestrian environment.
Tactile directional indicators are typically installed along pedestrian routes where additional tactile guidance can help people who are blind or have low vision navigate an environment. Applications may include transit facilities, plazas, shared streets, pedestrian areas, and other large or open spaces where conventional wayfinding cues are limited.
The appropriate placement and configuration depend on the facility, pedestrian route, applicable standards, and project design.
TufTile tactile directional indicators are designed to meet the dimensional criteria for guidance patterns established by ISO 23599, Assistive Products for Blind and Vision-Impaired Persons — Tactile Walking Surface Indicators.
Applicable requirements can vary by project and jurisdiction, so architects, engineers, and other project stakeholders should review the standards and specifications governing the individual project.
TufTile tactile directional indicators are surface-applied to the walking surface using mechanical fasteners and sealant. TufTile offers TDIs in 12-inch and 24-inch lengths, allowing individual units to be arranged to create the directional path required for the project.
Installers should follow TufTile’s current product-specific instructions for substrate preparation, placement, fastening, and sealing.
