If you’ve ever strolled through a bustling city street, wandered a shopping centre, or hurried through a train station, chances are you’ve noticed those curious rows of bumps and bars underfoot.
Maybe you’ve even tripped over them, cursed them for catching your shoe, or assumed they were a quirky design choice. But have you ever stopped to wonder what they’re really for?
It turns out that these mysterious markings—officially known as tactile ground surface indicators (TGSIs), or more colloquially, ‘braille trails’—are far more than just decorative flourishes.
They’re a vital part of making our cities accessible, and for many Australians, they’re the difference between independence and isolation.
The City of Brisbane Council recently spotlighted these unsung heroes of urban design and reminded residents to keep them clear and unobstructed.
Their message was simple but powerful: ‘Don’t stand, walk, or place items on braille trails. Keep them clear to help others.’
The response was eye-opening. Many locals admitted they’d never realised the true purpose of these markings.
‘I honestly thought it was just a flooring design,’ confessed one woman. Another echoed, ‘I doubt most people know the purpose of these. Good post.’
A third added, ‘Now that I know, I’ll be conscious not to be in the way.’
TGSIs are the long, raised strips or dot patterns embedded in footpaths, train platforms, shopping centres, and other public spaces.
They’re designed to be felt underfoot or detected with a cane, providing essential cues for people with vision impairment.
There are two main types:
- Directional indicators (long, raised bars) guide people safely along a path.
- Warning indicators (raised dots) signal a hazard or a change in direction, such as the edge of a train platform, a set of stairs, or a busy intersection.
For those who rely on them, these tactile cues are as important as traffic lights or street signs are for sighted people. They offer confidence, safety, and a sense of autonomy in otherwise daunting environments.

A quiet revolution in urban design
Australia began rolling out TGSIs in earnest in the late 1990s, following the introduction of the Disability Discrimination Act 1992.
National standards were developed to ensure consistency and effectiveness, and today, TGSIs are a legal requirement in most new public infrastructure and significant upgrades.
While many of us walk over them without a second thought, these markings are lifelines for people with vision impairment.
They help navigate busy thoroughfares, avoid hazards, and access public transport, making our cities more inclusive for everyone.
It’s easy to overlook the needs of others when we’re rushing about our day. But something as simple as not blocking a braille trail can make a difference.
Next time you’re waiting for a friend, parking your pram, or setting down your shopping bags, take a moment to check if you’re on a tactile path. By keeping these areas clear, you’re helping someone else move safely and confidently through the world.
