Analysis of the Current Situation of the Irrational Pavement for Blind

Unreasonable layout of pavement for blind

The popularization of pavement for blind should be synchronized with the development of cities. In some underdeveloped or medium-developed cities, city planning and leaders blindly pursue formality and civilization without actual research and investigation. Setting up a series of pavement for blinds in sparsely populated areas or narrow streets with mixed traffic is very unreasonable, because blind people generally do not go to places with a lot of pedestrian traffic. In such a low-carbon-dominated urban life, as a scientific city road planner, road planning should be based on the development level of the area and the main areas where blind people are active, so as to plan reasonably. In the future, the city's resource allocation can be updated and upgraded reasonably with the development of city planning.

Unreasonable design of pavement for blind

The pavement for blind should be 5mm higher than the ground, which is not very high but the design is unreasonable and can cause inconvenience to ordinary people's travel, such as women wearing high heels, playful children, and elderly people with mobility difficulties. It also brings a very uncomfortable feeling for baby carriages and wheelchairs. 

The texture of the tactile bars on the pavement for blind includes precast concrete bricks, granite, marble blind boards, ceramic blind boards, rubber and plastic blind boards, metal blind boards (mainly stainless steel), polymer material blind profiles. However, in practice, the price of pavement for blind materials determines the usage of materials. Therefore, most pavement for blinds use the same materials as ordinary roads, only the surface is cut into a pavement for blind shape. Pavement for blinds cannot be distinguished from ordinary road surfaces in terms of texture, which does not provide substantial help to blind people. The design of pavement for blinds in terms of color and texture does not distinguish the different needs of blind people, making it difficult to provide convenience for blind people. The texture of the widely used granite and marble blind boards can also be slippery in bad weather; the yellow pavement for blinds may wear and fade after sun and rain.

Pavement for blind illegally occupied

Public lack of accessibility awareness: The public's awareness of accessibility is weak, and the whole city has not formed an atmosphere of protecting pavement for blinds and facilitating disabled people. Some operating units and individuals arbitrarily damage and occupy accessible facilities. Pedestrians and small vendors on the street arbitrarily occupy the stainless steel indicator pavement for blinds. At the same time, there is a lack of education for the public. Some students walk on the pavement for blinds after school and take it as fun, but they do not know the consequences.

Maintenance and management work is weak, which makes the use efficiency of pavement for blinds low: Currently, almost all sidewalks in Wuhan are equipped with pavement for blinds, but there are still some problems with maintenance and management work. Many pavement for blinds are occupied by small vendors' stalls, telephone booths, and other facilities, and the stainless steel indicator pavement for blinds cannot function properly, making the pavement for blinds a virtual facility. Moreover, some pavement for blinds cannot be repaired promptly after damage, which reduces the efficiency of the pavement for blinds and brings great inconvenience to disabled people's travel. Pavement for blinds are often not cleared of snow and rain in a timely manner, which is not conducive to blind people's travel.
