Today, we're going to discuss the importance of tactile pathways, specifically Tactile Ground Surface Indicators or TGSIs. Can anyone tell me why these pathways are significant for individuals with visual impairments?
I think they help them navigate safely without bumping into things or getting lost.
Exactly! These indicators serve as a guide for visually impaired individuals, helping them navigate differently constructed environments safely.
How do we determine where to place them, though?
Great question! Placement guidelines are established by standards such as the Indian standards IS 4964, focusing on high-traffic areas like pedestrian crossings and building entrances.
What do those guidelines specifically suggest?
For example, at pedestrian crossings, hazard tactiles should be positioned 300 mm before the curb edge. This positioning starts to alert individuals to the need to navigate safely.
And at platform edges?
Good question! The guidelines recommend placing hazard tactiles at least 600 mm from the edge of the platform. This helps prevent falls and ensures safety.
To summarize, TGSIs are essential for aiding navigation, and their placement is carefully guided by standardized measures to ensure the safety of all users.

Now, let's dive into where tactile indicators should be placed within buildings and public spaces. Can anyone provide an example?
Maybe at the entrances of buildings?
Correct! At entry points of buildings, directional tactiles are crucial as they guide individuals from public transport areas to the building entrance.
What about inside the buildings?
Inside, they must be placed in corridors leading to key locations like lifts and exits. This ensures individuals can navigate through larger spaces efficiently.
Is there anything else we should keep in mind while placing them?
Absolutely! The guidelines also emphasize that tactile indicators should be flush with the surface to prevent tripping hazards. Placement needs to be practical and considerate of the overall environment.
So, in summary, tactile indicators are not only helpful at outdoor crossings but are also essential in buildings, guiding users safely along their journey.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section details the proper placement of tactile indicators, such as warning and directional tactiles, in various environments according to established standards. These recommendations aim to create safe and navigable spaces for visually impaired individuals, focusing on key areas such as pedestrian crossings, platform edges, building entries, and corridors.
Detailed
Placement Guidelines
The placement of Tactile Ground Surface Indicators (TGSIs) is critical for ensuring safe navigation for visually impaired individuals. According to Indian standards (IS 4964 and the Harmonised Guidelines & Standards for Universal Accessibility in India), the following guidelines are crucial for effective placement:
- At Pedestrian Crossings: Hazard tactiles should be installed 300 mm before the curb edge to alert users of an impending roadway.
- At Platform Edges: Hazard tactiles must be located at least 600 mm away from the edge of platforms to prevent falls.
- At Entry Points of Buildings: Directional tactiles should be placed to guide individuals from public transport points towards building entrances.
- In Corridors: Directional tactile indicators should lead toward lifts, reception areas, and exits.
These guidelines not only enhance the independence of visually impaired individuals but are also aligned with universal design principles, promoting inclusion and safety in public and private spaces.

Chapter Content
- At pedestrian crossings – Hazard tactiles 300 mm before curb edge
Detailed Explanation
This guideline specifies that tactile pavement indicators, which alert visually impaired individuals to potential hazards, should be placed 300 mm before the edge of the curb at pedestrian crossings. This spacing is crucial because it gives individuals enough time to detect the tactile surface and respond appropriately to the oncoming curb, ensuring a smoother and safer crossing experience.
Examples & Analogies
Imagine you are at a busy street. Just before the curb, there are special tiles you can feel with your cane. These tiles let you know you are approaching the edge safely, like a warning beep from a car letting you know it’s reversing. This helps protect you from stepping off the curb unexpectedly.
Placement at Platform Edges

Chapter Content
- At platform edges – Hazard tactiles at least 600 mm from the edge
Detailed Explanation
This guideline states that at train or bus platforms, the tactile indicators need to be positioned at least 600 mm away from the edge. This distance helps prevent accidents and ensures that visually impaired individuals do not inadvertently step closer to the platform edge where they could fall or risk being hit by oncoming trains or vehicles.
Examples & Analogies
Think of it like a safety rope you might use during a hike. Just as the rope keeps you a safe distance from a steep cliff, the tactile tiles at the platform help keep you from going too close to the dangerous edge of the platform.
Placement at Building Entry Points

- At entry points of buildings – Directional tactiles leading from public transport points
Detailed Explanation
Directional tactile indicators should be installed at entry points of buildings, guiding individuals from nearby public transport stops into the building. This principle ensures that once someone arrives via public transport, they have clear, tactile guidance about how to enter the building, enhancing their independence and navigational certainty.
Examples & Analogies
Imagine you are at a train station trying to find your way into a large building. The ground underneath your feet feels different where the tactile indicators are, like a trail marked by stones in a park. This helps you know where to go, making it easier to find the entrance.

- In corridors – Directional tactiles guiding toward lifts, reception areas, and exits
Detailed Explanation
In hallways and corridors, directional tactile indicators should be laid out to guide individuals toward critical points such as elevators, reception areas, or emergency exits. This guidance is vital for ensuring that individuals can navigate complex indoor environments independently and confidently.
Examples & Analogies
Consider being inside a big shopping mall—a place you’re not familiar with. The tactile paths are like having a personal guide who gently leads you by the hand, helping you find the elevator or the exit quickly and safely.
