City traffic light-free omnidirectional viaduct

Abstract

The invention discloses a city traffic light-free omnidirectional viaduct. The viaduct comprises a first main trunk traffic road, a second main trunk traffic road, a third main trunk traffic road and a fourth main trunk traffic road. The above four main trunk traffic roads are staggered to form a 3D groined omnidirectional viaduct. The center of the viaduct is provided with an annular lane. An outer ring lane of the annular lane is respectively connected to inner rings of the above four main trunk traffic roads through multiple viaduct approach bridges. The crossed position of each two of the main trunk traffic roads is a crossed point of the highest position of the climbing-up part and the lowest position of the driving-down part so that the main trunk traffic roads intervene with each other is avoided. The adjacent main trunk traffic roads are connected through an outer approach bridge at the crossed point. The city traffic light-free omnidirectional viaduct can be widely used for crossroads of the city, realizes smooth traffic flow and people flow when the city does not need traffic light traffic control, greatly reduces people time and city vehicle exhaust discharge, reduces traffic accidents and produces great social and economic benefits.

Description

technical field [0001] The invention relates to a traffic three-dimensional traffic structure at a crossroad, in particular to an omnidirectional overpass without traffic lights in a city. Background technique [0002] To solve the congestion problem of urban vehicles and pedestrians, it is one of the important measures to cancel the traffic control of traffic lights at cross (including T, the same below) intersections. To cancel the traffic lights, vehicles and pedestrians must be set up at the crossroads without hindrance. And the overpass bridge of existing bridge type can't reach the unimpeded requirement after erecting or erecting at the intersection of city. There are two reasons for this: one is to ensure that pedestrians can pass through the ground without barriers, and vehicles can turn on the bridge without barriers, so a multi-layer overpass must be erected, and the upper floors intersect at the highest point of the lower floors, resulting in higher overall bridg...

And the overpass bridge of existing bridge type can't reach the unimpeded requirement after erecting or erecting at the crossroads of the city

There are two reasons for this: one is to ensure that pedestrians can pass through the ground without barriers, and vehicles can turn on the bridge without barriers, so a multi-layer overpass must be erected, and the upper floors intersect at the highest point of the lower floors, resulting in higher overall bridges and extended sections. It is longer, occupies a larger area, and has a higher cost, so it cannot be generally implemented at urban crossroads; second, the existing bridge type overpass, whether it is a cross with several arc-shaped turning channels or other forms, has the problem of waiting for vehicles to cross , it just changes the overall waiting of the traffic light two lanes when there is no overpass into the crossing waiting of several branch roads when there is an overpass, so it cannot effectively solve the problem of urban vehicle and pedestrian congestion
