Non-interweaved ring flyover

Abstract

The invention relates to a non-interweaved ring flyover, comprising a track, multiple groups of left-handed ring-in ramps and ring-out ramps, wherein an entry where each group of the left-handed ring-in ramp enters the track is located outside of the track and an exit where the corresponding ring-out ramp leaves the track is located inside of the track. The left-handed ring-in ramp and the ring-out ramp of the ring flyover are respectively arranged on the outside and inside of the track, so that the ring-in and ring-out way is changed from the original external-in external-out way into an internal-in external-out or external-in internal-out way, i.e., the in-out on the same side is replaced with the in-out on different sides; and by changing the accessing way and accessing position of the left-handed ring-in ramp and the ring-out ramp, the interweaving of the track is eliminated, and the rounding angle of vehicles on the track is reduced.

Description

technical field [0001] The invention belongs to the technical field of overpasses, in particular to a ring-shaped overpass without weaving. Background technique [0002] Interchange (interchange for short) is an important traffic organization facility of modern urban road system. Ring interchanges are widely used in interchange construction because of their compact layout, less land occupation, and low cost. However, practice has proved that the existing ring interchanges are not suitable in many cases, such as the central area of ​​a megacity, the intersection with a large left-turn traffic volume, etc. [0003] The roundabout is evolved from the roundabout, and the turning of vehicles in all directions is realized through the roundabout. According to the separation level of traffic flow, ring interchanges can be divided into two-layer, three-layer, four-layer and other forms. Taking the intersection as an example, the three-level roundabout (such as figure 1 Shown) is ...

AI Technical Summary

Problems solved by technology

Generally speaking, the current roundabouts are only suitable for left-turn traffic with small traffic volume and low speed, and the interweaving of the roundabouts is the fundamental reason for the low quality of operation

[0006] In addition, the overpass occupies a large area, resulting in a large area of ​​isolation, and the difficulty of pedestrians crossing the street is a common problem in urban overpasses in my country at present.
