Simple fly-over T-shape crossing

Abstract

The invention is a simple 3D crossing T-shaped intersection, a novel T-shaped road intersection, simple-structured, small-scale, excellent-performance, convenient to construct, cost-saving, and widely applied. And it is composed of two one-way through bridges spanning trunk road with interval turning lane and intersecting road and connecting the trunk road with the intersecting road through flat ramp, or a one-way through bridge spanning trunk road and intersecting road and a footpath spanning the trunk road and the intersecting road. And it uses the through bridge spanning the trunk road to implement 3D-crossing complete or limited interconnection, increasing flux and efficiency of T-shaped road intersection, improving intersection traffic order and assuring city roads are smooth in high efficiency. And it can be used in reconstruction of intercity highways, city fast trunks, or T-shaped road intersections in city zones, limited by surroundings, and exert its efforts to improve city traffic environments and speed up complete and sustainable development of cities.

Description

technical field [0001] The invention is an improvement of a three-dimensional intersection at a road intersection. Especially a kind of simple and convenient three-dimensional intersection T intersection. technical background [0002] There are many T-shaped intersections in the urban road network. When the traffic flow is busy, the T-shaped intersections become traffic bottlenecks and are more difficult to navigate than intersections. In the existing technology, signal light control management is usually applied to T-shaped intersection traffic, but the advanced computer intelligent control signal light management still cannot avoid parking and waiting, so the traffic flow is greatly restricted. In reality, there are relatively few applications of three-dimensional intersections at T-shaped intersections, and they are usually large and complex, with huge land occupation and construction costs.

In the existing technology, signal light control and management are usually used for T-shaped intersection traffic, but advanced computer intelligent control signal light management still cannot avoid parking and waiting, so the traffic flow is greatly restricted

In reality, there are relatively few applications of three-dimensional intersections at T-intersections, and they are usually large and complex, with huge land occupation and construction costs

Chinese patent (01114211.1) "T-junction single-layer three-way overpass" is a T-junction three-dimensional intersection design with relatively simple intersecting roads and bridges across the main road, but its overhead ramp has a single length and performance, and the construction cost is also considerable
