Pavements are now designed with truncated domes that raise the platform to guide and regulate foot traffic.

Walking on pavements is considered safer because these areas are dedicated to walking. Also, walkways have been made safer with technology like ADA truncated domes that are raised surfaces created to help people in walking.

So, what are these raised surfaces, and why are they important

To understand the value of raised surface, you need to study the architecture of a footpath

A footpath is a walkway for people of all abilities including the visually impaired and wheelchair borne. Everyone is free to access the footpath but they should feel safer and convenient to walk. Usually, footpaths run parallel to driveways on one side and buildings on the other. While normal people could see the footpath, those with visual impairment can’t.

Cast iron tactile is slightly raised which gives a different feel and an assurance that you are in the safe area. You can take long strides on these tiles without any worries or apprehension. Also, they are useful for people with visual impairment as they can feel the difference between normal tiles and feel safer.

Does a raised platform fulfill its objective?

Yes, it does. The objective is to keep people safe by guiding the foot traffic. The truncated domes direct people to sideways and specific areas like escalators, lifts, and foot-over bridges. If you walking on raised tiles, you will feel that you need not jump on either side of the platform.

Here’re the advantages of raised platforms

1. Prevent slip and fall accidents

ADA truncated domes can prevent slip and fall accidents by providing a surface where you can place your feet firmly. Here you can’t slip even when the tiles are wet. For example, you can easily take a walk over wet tiles, if they are special tiles.

2. Guiding people

Walkers follow the raised platform to maintain their speed. They know where the tiles are headed for and whether they are on the wrong way or right. The change in the surface is sufficient to send a warning signal to people especially children that are taught to be alert as soon as they jump on a raised surface.

3. Assistance

People with difficulties with walking like those walking with walkers, canes, or in a wheelchair need not putting extra effort into accessing a raised surface. They can easily go to either side of cast iron tactile with little effort.

How are the truncated domes made?

Tiles with spikes are made of material that make them 100% safe from foreign elements like water, sun, and dust. Also, they can take much punishment from footwear and keep working as new for a long time. Also, they can be replaced with new tiles as and when required. Also, they are available in various colors and designs to meet different needs.

ADA truncated domes are used everywhere including schools, malls, offices, and public places that receive a high footfall. These tiles can be found in airports, railway stations, bus stands, and everywhere. And they will remain in use in the coming days.
