Human rights are a great deal for everybody. Even those with disabilities should be treated with utmost respect and should be offered the same privileges as normal people. This is why visually impaired individuals are allowed to work and walk the streets, provided the right safety measures such as the use of detectable warning tiles are present.
To make a good boundary for the road and sidewalk, curb ramps were installed in corners. But the problem with this is that the visually impaired find it hard to distinguish the boundary itself. This is why tactile surfaces are placed on the walking surfaces of the ramps so the visually impaired can get a warning that they are approaching the road.
However, these surfaces are not perpetual. They can get damaged by cars, feet and industrial vehicles especially if these are made from low grade materials. To prevent early damage and high maintenance costs though, authorities have made specific rules embodied in the Americans with Disabilities Act to make sure the right materials are chosen.
Tactile surfaces can be made from ceramic, stainless steel, concrete, precast, plastic or latex. Each has its own pros and cons in terms of durability and maintenance requirements which authorities must take note of. Regardless of what materials are used to manufacturer them, it is necessary that they have truncated domes that comply with specific rules.
Each dome of the tile must have a diameter measuring . 9 to 1.4 inches. Its top must be around 50 percent to 65 percent in measurement compared to its base. Each dome must be . 2 inch exactly in height, and must be placed adjacent to each other at a distance of 1.6 inches to 2.4 inches from the center with the bases . 65 inch in distance.
Light colored roads must install darker warnings, while darker ones must have lighter warnings. This will assist the visually impaired in recognizing the difference in color more distinctly. Tests must be done to make sure the warnings can be detected under foot and by the use of cane, and are not prone to slippage.
There are several things authorities must take note of when selecting detectable warning tiles to install. Nevertheless, it would help to find a reliable manufacturer who can guarantee durable materials at the right price and warranty.
