Pedestrian bridge is also known as pedestrian overpass. Generally built in traffic flow, pedestrian dense lot, or intersection, square and railway above. Pedestrian bridge only allows pedestrians to pass, to avoid the intersection of traffic and pedestrian flow intersection, to ensure the safety of people through, improve the speed, reduce traffic accidents.Pedestrian Bridge
According to the structure of the distinction, the common cross the bridge can be divided into three categories, namely, hanging structure, supporting structure and hybrid structure. Suspended structure of the bridge over the bridge as the main load-bearing components, for pedestrians through the bridge itself is not load-bearing, hanging in the bridge as a load-bearing beam, the structure of the bridge over the bridge will be structural components and practical components in the Together, can reduce the use of building materials, the relative reduction in the cost of the project, but this structure of the bridge overpasses unusually thick and strong, so pedestrians on the bridge line of sight will be blocked railings, and stout bridge railings is difficult to give people the feeling , And thus in the urban landscape function is lacking.
The bridge of the supporting structure bridges the load-bearing bridge directly on the piers for pedestrians to bridge the bridge over the bridge, while the bridge railings only protect the pedestrian's role and do not bear the weight of this type of overpass bridge High, but because the bridge railings slender and beautiful, as the city landscape function is better, so the current city of this type of overpass bridge the most popular. The hybrid bridge is a hybrid of the above two structures, and the bridge and the bridge share the load of the bridge as a load-bearing structure.Pedestrian Bridge
In addition to the above three main structure, there are some cities in some blocks will be suspension bridge, cable-stayed bridge structure for the construction of the bridge over the street, but these special structures over the street flyover is expensive, the choice of these specific structures, mostly out In the city landscape considerations, not the mainstream of the street overpass. In order to facilitate and attract pedestrians to use, some places of the bridge installed electric escalators, from pedestrians to climb the rung. Some flyover also has lifts for people with disabilities. Part of the flyover is also equipped with automatic pedestrian, to reduce the distance of the line. In addition, some overpasses are covered, some are more sealed, with air conditioning.Pedestrian Bridge
