Problems solved by technology

[0002] At present, in order to solve urban traffic congestion, various three-dimensional transportation methods have appeared, but in general, either the number of floors is too many, so the bridge body is too high and the floor area is large, or the number of floors is small, but The occupied area is not small enough; or in the same overpass, some lanes are relatively crowded, while others are relatively free; or the form is single, unable to meet the requirements of many special situations, and in the interrelated traffic structure, Can't completely solve the fundamental problem
In the modern urban traffic structure, many places cannot meet the requirements for the actual land occupied by its construction

Embodiment Construction

[0025] In the figure, the road section or the general road plane that is basically parallel to the general road plane is called a plane section. Generally, the road section where the vehicle is located when changing direction is a plane section; the upward or downward driving is called an oblique travel; Generally, there is no direction change during the oblique travel process; generally, among parallel vehicles, the vehicle that needs to turn travels on the left side that no longer turns. Where the solid line intersects with the dotted line, the dotted line part represents one of the three methods: the convex zigzag surface yields to the concave zigzag surface, the convex zigzag surface yields to the general road plane, and the concave zigzag surface yields to the general road plane The relatively low place in the mile is a concave curved surface or a general road plane. The solid line part represents a relatively high place in one of the above three ways of giving way, which...

Abstract

The invention discloses a miniature practical overpass bridge. Lane widths are designed reasonably according to traffic flow on a construction basis of a cross structure. Under limited terrain space conditions, each lane is provided with a passage allowing vehicles on other lanes to cut in when having a passage allowing vehicles to separate out. Requirements of differences of a main stem and branches in a cross road on each lane width are taken into full consideration. The miniature practical overpass bridge in an all-direction stereo cross structure is small in size, flexible and variable in form and adaptive to different conditions and can be constructed in small-area places, thereby being a move effective and feasible scheme for thoroughly solving urban traffic congestion.

Description

technical field [0001] The invention relates to an urban traffic road structure, in particular to a method for realizing two-story omnidirectional three-dimensional traffic on a cross-shaped intersection road. Background technique [0002] At present, in order to solve urban traffic congestion, various three-dimensional transportation methods have appeared, but in general, either the number of floors is too many, so the bridge body is too high and the floor area is large, or the number of floors is small, but The occupied area is not small enough; or in the same overpass, some lanes are relatively crowded, while others are relatively free; or the form is single, unable to meet the requirements of many special situations, and in the interrelated traffic structure, Can not completely solve the fundamental problem. In the modern urban traffic structure, many places cannot meet the requirements for the actual land occupation of its construction. Contents of the invention [...
