Construction of Pavement for Blind People in the City
"At a busy intersection, the green light was on, but a car stopped. The panicked driver kept waving his arms and shouting desperately,'I'm blind! I'm blind! I'm blind!' Then the blindness spread rapidly. The entire city has fallen into an unprecedented disaster..." This is the description in the Nobel Prize winner José Saramago's masterpiece "Blindness".
In real life, a seemingly convenient city is difficult for 5 million blind people to move an inch.
If you pay attention, you will find that the city's pavement for blind may be cut off by the reconstructed building at any time, or stop at a certain parking lot, some of which are paved to the wall and motorway, and even more, it leads directly to the river...wherever blind tracks go, there is danger.
In the urban road planning and construction, pavement for blind people is an indispensable facility. Whether a city’s pavement for blind people is unobstructed reflects whether the city cares for disadvantaged groups including the disabled, and also shows the level of urban management and even social management.
The construction boom of pavement for blind people in China began in 2005. During this year, the "National Civilized Cities" began to be selected, and the coverage of blind roads became an important indicator. After more than ten years of construction, China has now built the world's longest and most widely distributed pavement for blind people, and the material of the blind track has also evolved from the original blind track brick to the metal blind track.
One is the go-ahead pavement for blind people. The blind path should be able to guide the visually impaired to walk safely and reach the location of barrier-free facilities smoothly, in a strip shape.
The other is a warning blind sidewalk set up at the starting point, end point and corners of the pavement for blind people, which can inform the visually impaired that the spatial environment of the route ahead will change, which is in the shape of a dot.
