代写论文-Sidewalks are used to distinguish different paths of pedestrians, bicycles, the disabled, and the road for vehicles. Sidewalks separate public and private space by its different distributions and usages. For example, there are always sidewalks around private houses to separate the private space from the road and other public constructions. These sidewalks are not only used for pedestrians to walk but also a sign of a family’s territory. Most of these sidewalks are regulated by signs and guideposts. Sidewalks are distributed along two sides of the road to protect pedestrians and private properties from the vehicles on the road.
In the commercial district, sidewalks are closely distributed. They are distributed along the road, around public buildings like malls, bus stations, and parking lots. These areas are always crowded with people and vehicles, especially the rush hour. Thus, sidewalks in these areas not only provide paths for pedestrians but also help reduce the danger from vehicles. Also, in public buildings like malls, there are also sidewalks with specific functions, especially those for the disabled. Besides, sidewalks around schools are arranged for the safety of students. Sidewalks in these areas play a more important role of safety because these areas are always crowded with pedestrians and vehicles. And these sidewalks are also used to clarify the direction along with signs and guideposts because road distributions in these areas are complex.
On the other hand, sidewalks in the residential district are separately distributed. There are few areas where pedestrians and vehicles stay close to each other, so sidewalks in the residential district play a less important role in safety. The main function of sidewalks in this district is to separate the private property of each family and protect their property from vehicles on the road. There is no sidewalk specific for the disabled or children because people choose vehicles as their main transportation tool, instead of walking.
