Problems solved by technology
But so far, there are few studies on the site selection of pedestrian bridges at home and abroad, and urban pedestrian bridges are often used as independent facilities
At the same time, when designing, design units or designers generally only focus on a certain problem, and lack of systematic consideration, which often makes it difficult for the cost performance of urban pedestrian bridges to achieve the expected results, and affects the performance of pedestrian bridges

Embodiment Construction
[0036] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 As shown, a site selection method for urban pedestrian bridges that is suitable for moving and avoiding quietness includes:
[0038] S01. Determine whether the pedestrian bridge area to be built belongs to an intersection, if not, execute step S02, and if it does, jump to step S05;
[0039] S02. Collect and process the basic road condition information in the area to be selected, and obtain the average vehicle speed-vehicle density curve fitting diagram and the vehicle speed distribution diagram of the road section;
[0040] S03. Quantitative analysis of pedestrian bridge site selection: According to the average vehicle speed-vehicle density curve fitting diagram in step S02, it is determined that when the pedestrian bridge is structurally damaged, the probability of hitting the vehicle under the bridge is less than P ...

A site selection method for urban pedestrian bridges suitable for moving and avoiding quietness, including: (1) judging whether it belongs to an intersection, if not, performing step (2), otherwise, jumping to step (5); (2) collecting and processing Road condition information of non-intersections; (3) Calculate the vehicle safety guaranteed speed when the collision probability is less than the design probability; (4) According to the vehicle speed distribution map, select the area greater than the vehicle safety guaranteed speed, and jump to step (7); ( 5) Collect and process the road condition information at the intersection; (6) The maximum area ratio of the pedestrian bridge to the intersection when the impact probability is less than the design probability; (7) Consider the bridge shape, environment and other factors to determine the construction location of the pedestrian bridge. The site selection method for the overpass of the present invention can reduce the possible casualties caused by the structural collapse of the pedestrian overpass to a certain extent, and is especially suitable for cities with many vehicles and heavy traffic.
Description
technical field [0001] The invention belongs to the technical field of traffic planning, in particular to a site selection method for urban pedestrian bridges suitable for moving and avoiding quietness. Background technique [0002] In recent years, with the development of economic construction, my country's urban traffic has become increasingly developed. In order to improve the traffic capacity of the urban road network and ensure the safety and convenience of pedestrians crossing the street, the construction of urban pedestrian crossing facilities is increasing, the main one of which is the construction of pedestrian bridges. The construction of urban pedestrian bridges has good traffic and social benefits for increasing the speed of vehicles, realizing the separation of people and vehicles, improving traffic congestion, and improving the walking quality of urban residents. It has become an indispensable part of the urban traffic system. It has been paid more and more att...
