City traffic light-free omnidirectional viaduct

Abstract

The invention discloses an omnidirectional overpass bridge without traffic lights in a city, which comprises a first main road, a second main road, a third main road and a fourth main road, and the above four main roads criss-cross to form a three-dimensional well-shaped omnidirectional overpass; the overpass The center of the center is provided with a circular driveway, and the outer ring lanes of the circular driveway are respectively connected to the inner rings of the above four main roads through a plurality of viaducts. The highest point of the upper bridge and the lowest point of the lower bridge are used as intersection points at the positions where the four main roads intersect in pairs, so that there is no interference between the main roads. Adjacent arterial roads are connected by outer approach bridges at intersections. It can be widely used in various crossroads in the city, canceling the traffic control of traffic lights in the city, making the flow of cars and people in the city unimpeded, greatly saving people's time, reducing the exhaust emissions of urban vehicles, and reducing traffic accidents to a certain extent. Thereby generating greater 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
