When we are travelling, we tend to miss many things around us because we are constantly in a rush. We are rushing to catch a train, to reach work, to meet someone, or simply to get through the day. Our eyes become so accustomed to familiar surroundings that they filter out everything that does not demand immediate attention. However, sometimes the most interesting and helpful elements lie right in front of us - like the yellow tiles at metro stations. Have you ever noticed them? Or questioned what they are for? It may surprise you to learn that these yellow tiles are not for decoration or aesthetics; they serve a much deeper purpose in helping commuters, especially those with visual impairments, move from one place to another safely. Here is what these tiles mean and how they play a vital role in public accessibility.

Who Invented Tactile Paving and Why Yellow Tiles Matter in Metro Stations
The concept of tactile paving was first introduced by Japanese engineer Seiichi Miyake in the 1960s. Sometimes referred to as tenji blocks, Miyake developed tactile pavement to help his visually impaired friends navigate public areas such as train stations and stairways through the sense of touch. This innovation was first implemented in Okayama City in 1967, and it quickly gained popularity across Japan and, eventually, around the world. Today, tactile paving is a global accessibility tool to aid visually impaired individuals in navigating safely across urban environments.
Two Types of Tactile Paving Used in Metro Stations for Visually Impaired Commuters:
There are two primary types of tactile tiles found in metro stations and other public spaces:
1. Directional Tiles
These tiles have elongated, raised lines that form a tactile and visual path. They guide individuals along a specific route, such as walkways or footpaths, and indicate the direction to follow.
2. Warning Tiles
These tiles feature raised bumps arranged in a grid or offset pattern. They are designed to alert users to potential hazards such as platform edges, steps, curbs, or a change in direction. They act as a cautionary signal for visually impaired pedestrians to stop or proceed with care.
How Asian Countries Use Tactile Paving to Improve Metro Accessibility
Several Asian countries have widely adopted tactile paving to support accessibility for the visually impaired. In Japan, tactile paving is not limited to metro stations. It is found on pavements, staircases, and inside public buildings, making navigation significantly easier for many. India has also implemented tactile tiles across various metro networks, particularly in cities like Delhi and Mumbai, in line with the Accessible India Campaign. Other countries in Asia-such as South Korea, Singapore, and Malaysia-have incorporated tactile paving into their public infrastructure to improve inclusivity and safety.
Global Examples of Tactile Paving in Metro Systems and Public Transport
Around the world, tactile paving is recognised as an essential accessibility tool for public spaces. In the United Kingdom, the Tyne and Wear Metro became the first rail network in England in 2022 to complete the installation of tactile paving on every platform edge. This move was a significant step forward in making rail travel safer for visually impaired passengers.
Denmark has developed a standardised tactile system known as "Intactila", which is integrated into outdoor paving designs across cities. In North America, the United States mandates tactile warning surfaces on public transport platforms as part of the Americans with Disabilities Act (ADA) of 1990. Canada has followed suit, with cities like Toronto and Vancouver implementing similar systems.

Australia has also taken a structured approach to tactile paving. Cities such as Sydney have integrated yellow tiles along with a colour-coded system as part of the country's 2007 legislation focused on disability and equality laws.

So, Why Yellow Tactile Tiles Are Essential for Accessible Metro Travel
The yellow tiles at metro stations might seem insignificant at first glance, but they serve an important purpose. Designed to support visually impaired individuals, these tactile paving systems play a crucial role in promoting accessibility, independence, and safety in public spaces. So the next time you walk across those yellow tiles, remember - they are not just part of the flooring. They are a pathway to inclusion.
