Tai chi pattern type cross overpass highway

Abstract

The invention discloses a tai chi pattern type cross overpass highway. The double-deck tai chi pattern type cross overpass highway comprises a north-south-direction lane with a trunk road at the lower layer and an east-west-direction lane with a trunk road at the upper layer, wherein at the cross of the north-south-direction lane and the east-west-direction lane, a northbound left turn lane, an eastbound through lane, an eastbound left turn lane, a southbound left turn lane, a westbound through lane and a westbound left turn lane are taken as lanes of the upper layer of an overpass, a north-side overpass lane formed by the northbound left turn lane, the eastbound left turn lane and the eastbound through lane is in an inner spiral shape from east to west, a south-side overpass lane formed by the southbound left turn lane, the westbound left turn lane and the westbound through lane is in an inner spiral shape from west to east, and the shape of the north-side overpass lane and the shape of the south-side overpass lane form a tai chi pattern. The tai chi pattern type cross overpass highway has a compact and simple structure, so that the space is fully used, a small land is occupied the cost is low, and the lane direction is clear.

Description

technical field [0001] The invention relates to an overpass highway, in particular to an overpass highway crossing in a Taiji style. Background technique [0002] Two highways (streets) intersect to form four major entrances and four major exits. Mathematically, it can be attributed to the intersection of four directed line segments on the same plane, resulting in four different directions. However, the driving direction of the road (street) is not only straight, but also horizontally left or right, so each entrance is connected to the other three exits, so there are 12 directions. For driving safety, the traffic police department has set up traffic lights at road intersections, but setting up traffic lights greatly limits the speed of vehicles, resulting in frequent traffic jams, wasting energy, etc. some adverse effects. In order to solve this problem, people have researched and introduced various overpass schemes, and have received certain good results. As Chinese pate...

AI Technical Summary

Problems solved by technology

Although the above-mentioned technical scheme achieves the three-way intercommunication of going straight and turning left and right, the direction of the lanes is partially overlapped, and the overpass in the right lane still needs to occupy the left lane, so that the traffic flow in the left lane is limited. When the traffic volume is large, it is still easy. cause congestion

However, other existing overpass design schemes that can effectively control the congestion phenomenon either occupy too much land area, or have too many layers, complex structure, high cost, etc.
