Background

Sidewalks refer to portions of a road that are dedicated to pedestrian traffic that are separated by curbs or guardrails and other similar facilities. Sidewalks are very common in cities, and sidewalks are arranged beside general streets. Grass or trees are arranged between the sidewalk and the motor vehicle lane in some places. The sidewalk is less in the country. Legislation in many areas of developed countries requires removal of all facilities on sidewalks that are inconvenient for disabled persons, so that where roads are being traversed the sidewalks are exclusively lowered to the same level as the roads for wheelchairs to traverse the roads. The sidewalk is one of important components in urban roads, and along with the rapid development of cities, the sidewalk is not a special passage for pedestrians to pass through in use, is endowed with a new connotation in the development of the cities, and plays an important role in dredging urban traffic, building urban landscapes, utilizing underground spaces and depending on urban public facilities.
