There are two types of the blind path surfaces, one is the blind path that guides the visually impaired to go straight forward through the sense of feet. It has a long strip surface, called walking blind path; the other one can inform the visually impaired people to turn off or remind them of the end of the blind path. It is called the tactile ground surface indicators
. In addition to the above functions, the tactile warning surface indicators
still needs to be paved separately at the location and entrance of the main municipal facilities and buildings in the city. This can inform the specific location of the facilities for the disabled and help them to know the surrounding environment, such as various sidewalk entrances, city square entrances, bus waiting stations, pedestrian overpasses, upper and lower entrances of pedestrian tunnels, building entrances, subway entrances, platform edges, obstacles on sidewalks and so on. With regular surroundings and facilities, the visually impaired people can walk conveniently under the corner sense of blind stick, such as edge stones, flower stages, walls, and other facilities set outside the sidewalk. These are the better ways for the visually impaired people to walk in.
Yellow is bright itself. For amblyopia and the visually impaired people with light sensation, visually, yellow is more obvious than other colors, so it is easier to be noticed. The tactile paving
in Japan is medium yellow. Blind paths not only guide the visually disabled people to walk but also protect their safety and the space that does not hurt people. Therefore, the position of the blind path among the sidewalks is very important. It is purposeful for people with visual disabilities to go out, such as going shopping, going to public transport stations, crossing the road and so on. They all need the guidance of a blind path. People with visual disabilities can distinguish where they are by hearing and memory, which are different from ordinary people.
