What Are the Design Specifications for Tactile Floor Indicators?
With the development of modern society, our road design is also very suitable for the needs of the public, and it is becoming more and more humane. There are road designs for ordinary people and road designs for the visually impaired. So what are the design specifications for tactile floor indicators? Let's follow Xiongchang to find out!
The surface of the tactile floor indicator has two forms. One is the tactile bar that guides the visually disabled to continue walking straight forward through the sense of feet. The surface is a long strip, which is called the go-ahead blind sidewalk. The other is to inform the visually disabled that they should turn on the blind sidewalk or it is the end of the blind sidewalk. The surface is in the shape of a dot, which is called the prompt blind sidewalk.
In addition to the above functions, the locations and entrances of major municipal facilities and buildings in the city still need to be separately laid with tactile floor indicators, which can inform the visually disabled of the specific location of the facilities and assist the visually disabled to understand the surrounding environment, such as all kinds of sidewalk entrances, city square entrances, bus terminal stations, pedestrian overpass, the upper and lower entrances of pedestrian underpasses, building entrances, subway entrances and platform edges, obstacles on sidewalks, etc. Regular environment and facilities can make the visually handicapped easy to travel under the sense of blind cane. For example, the standing edge stone, flower stand, fence and other facilities set on the outside of the sidewalk are the best way for the visually handicapped to walk. The yellow itself is brighter, and it is more visually obvious to the amblyopia and the visually disabled people with light perception than other colors, and it is easier to find.
The blind sidewalk not only guides the visually disabled to walk, but also protects them in a safe and harm-free space, so the positioning of the tactile floor indicator in the sidewalk is very important. The visually disabled travel for a purpose. For example, go shopping, go to public transportation stations, cross intersections, etc.. These require the blind sidewalk to guide the visually disabled, so they can distinguish their location through their hearing and memory that are different from ordinary people. The requirements on the positioning of the tactile floor indicator: one is to protect the safety of the visually disabled when they are walking and form a space that is not harmed; the second is to reduce the interference of pedestrians to them in places with fewer pedestrians, or to reduce the occupied position of pedestrians on the blind sidewalk; the third is that there are many people entering and exiting the entrances of stores in shopping malls and commercial streets, so it is suitable to keep these two stay away with each other. Therefore, it is the best location for blind sidewalks to have facilities such as standing edge stones, green belts or fences on the outside of the sidewalk.
The width of the blind sidewalk is formulated based on American practical experience and Japanese tests. The average step length of adult men aged 15 to 50 is 0.75m, the shoe length is 0.25m, and the net step length is 0.50m. Therefore, the width of the blind sidewalks, intersections, and curb ramp sides with the function of hint in the lateral direction of the sidewalks should be set so as to meet the requirement of preventing from being crossed by walking. For the blind sidewalk that guides straight walking, as long as one foot can step on it, the width is 4 to 6cm. In order to take into account the left and right swings of the visually impaired walking footprint, the design width is 2 bricks (0.25m×2). The direction of the sidewalk square brick paving seam of the road horizontal curve and the widened section of the intersection will deviate the direction of the road. The blind sidewalk paved by this paving seam will bend repeatedly and cannot be used, which has taught us many lessons. For curved paving, the direction of the blind sidewalk should be basically consistent with the direction of the road, and the blind sidewalk should be paved into a curve with triangular paving seams. It is also possible to turn the blind sidewalk to an angle and continue walking forward in a straight line along the direction of the curve.
The cross of the blind sidewalk: this point is to induce the visually disabled to turn, and can reach intersections, bus stops, shopping malls and other places to achieve the function of the blind sidewalk. For this reason, a prompt blind sidewalk is used at the intersection to inform the visually disabled that the blind sidewalk needs to change direction, or it is the end of the blind sidewalk, or the destination has been reached. In order to prevent walking across, the paved area should be larger than the width of the straight blind sidewalk, and symmetry should be considered. Pave the blind sidewalk at the sidewalk to inform the visually disabled to pay attention to where they are and they have passed the crosswalk. In addition to the appropriate requirements for the width of the tactile floor indicator, the visually disabled also have requirements for the length of the blind sidewalk. Paving the blind sidewalks at the places entering the crosswalk will be very helpful for the visually handicapped to pass the crosswalk.
The above content is the design specification of the tactile floor indicator introduced by Xiongchang today. Then in a modern civilized society, when we encounter the visually impaired, we must be courteous and work together to create a civilized city and strive to be civilized citizens.
