What Those Bumps on the Sidewalk Are Really For

Dangerous is one of the words that can describe a rather populous city, especially for people with vision problems. Tactile paving is installed on different parts of the street to help them navigate and to warn them about changes in the road or traffic. Each paving has its own purpose and makes city life a little bit better for the visually impaired.

Bright Side invites you to expand your knowledge and discover what the different types of bumps mean. Let’s go!

Blister paving

This type of paving is used for pedestrian crossings. It shows a thick line of bumps placed in a rectangular pattern. It’s usually installed next to crossroads. Such paving shows people with visual impairments that they can cross the road in that place and that they should be careful.

Corduroy paving

This kind of tactile paving has rounded bumps that are arranged in a rectangular pattern but they’re a bit thinner than blister paving. This kind of tile is paved lengthways in the direction a pedestrian is walking. You can find them at the beginning or end of steps and at level crossings. This way, people with bad vision can be warned about the changes on the floor they’re waking on.

Offset blister paving

This paving’s surface has equally spaced out round and flat-topped blisters. It’s also used to warn visually impaired people about their surroundings. Usually, such bumps are put along train platforms as well as at tram and tube platforms.

Tiles with long stripes

Such tiles indicate that the path has no obstacles or danger ahead and it’s safe to go forward.

Horizontal and vertical stripes combined

Sometimes roads can get mixed. In this case, 2 types of tiles are used to indicate what the different parts of the path are meant for. If the tiles are laid along the road in the direction you’re traveling, it’s meant for bikes. Tiles put across the street are to indicate the way for pedestrians.

Do you have this kind of tactile paving installed in your city? Do you know more clever installations that can make cities more accessible to everyone? Let’s discuss this topic in the comment section!
