What Is a Footbridge?
Pedestrian overcrossing is also called pedestrian overpass. It is usually built on a lot of traffic, dense pedestrian areas, or above intersections, squares and railways. Pedestrian bridges only allow pedestrians to pass, and are used to avoid conflicts when traffic flow and pedestrian flow planes intersect, to ensure safe crossing of people, increase vehicle speed, and reduce traffic accidents.
- According to the structural distinction, common street flyovers can be divided into three categories, namely suspended structures, supporting structures and hybrid structures.
- Suspension structure overpasses use bridge railings as the main load-bearing component. The bridges used by pedestrians are not load-bearing themselves and are suspended from the bridge rails as load-bearing beams. This structure of overpasses combines structural and practical components Together, it can reduce the use of building materials and relatively reduce the cost of the project. However, the railings of the overpass bridge of this structure are extremely thick and sturdy, so the pedestrian's view on the bridge will be blocked by the railing, and the thick bridge railing is difficult to give people a beautiful feeling. And therefore in
- In addition to the above three mainstream structures, there are some cities that use the structure of suspension bridges and cable-stayed bridges in the construction of overpasses in some streets, but
- In order to facilitate and attract pedestrians, escalators have been installed in the flyovers in some places to prevent pedestrians from climbing up the steps. There are also lifts in some flyovers for the disabled. Some flyovers are equipped with moving walkways to reduce the distance between pedestrians. In addition, some overpasses are covered, some are sealed and air-conditioned. [1]
