The Importance of Blind Way Recognition
Most blind ways in current cities are not fully utilized, and an effective method is needed to improve the usage rate of blind ways. The current feasible solution is to implant an electronic information guidance system in the blind path. However, its implementation still requires significant cost because it requires large-scale reconstruction of existing blind ways and reconfiguration of road construction, which is obviously not the optimal solution. Instead, a blind path recognition system based on image processing is relatively feasible.
Compared with large-scale reconstruction of blind ways, this electronic image processing solution is obviously more cost-effective and has similarities with vehicle navigation systems, making it more valuable for research.
According to Maslow's hierarchy of needs theory, human needs are distributed in a staircase shape from low to high, namely physiological needs, safety needs, belongingness and love needs, esteem needs, and self-actualization needs. Therefore, after meeting the most basic physiological needs of humans, safety needs become the most important aspect to be considered. The right to life is the most fundamental right of humans, and the blind population needs this basic human right more, and they also need more respect. Therefore, any unsafe behavior on the tactile bars of blind ways should be prohibited.
Humans are not solitary animals and need to travel to integrate into collective life. Therefore, travel becomes one of the most basic social activities. Especially for blind people, their travel conditions and convenience should be given priority consideration. The socially disadvantaged groups have difficulties in daily life and movements, so it is more important for normal people to create convenient channels for their lives. The tactile bars of blind ways should be comprehensively protected and potential blockages should be minimized, as well as the risk of encroachment or damage.
As a form of urban road construction, the construction of blind ways should not only consider their convenience but also not neglect their aesthetics. Based on ensuring the safe travel of blind people and other disabled individuals, it should also strive to meet their psychological needs and physical comfort. The design of a good blind path space environment should comprehensively consider factors such as climatic conditions, street facility availability, and noise impact. Through coordinated planning of vegetation landscapes and buildings, it should also avoid factors such as excessive exposure to sunlight or darkness, strong winds and rains, and severe environmental pollution, in order to provide blind people with the best possible travel experience.
