Method and road structure for run of road junction without block

Abstract

The present invention discloses a method for smooth running at the crossroad and the road structure. In the method a single-layer main bridge and auxiliary bridge of the longitudinal straight-going roadway and the longitudinal reverse-going roadway, and the lower part of the main bridge is arranged with a roadway for the left turning and turning over of the vehicle. The vehicles turning left or turning over are leaded to running through the roadway under the bridge and the auxiliary bridge, and the traversing of the vehicle turning left and turning over through any straight-going roadway is avoided. The invention effectively settles the smooth running problem of vehicle running in different directions at the crossroad. The invention settles the smooth running problem of vehicle running in different directions at the crossroad only with the single-layer overpass, and therefore the invention has the character of low fabricating cost. As the overpass is built on the original transverse roadway and does not take too much area, the invention has the advantage of small accommodation area and is suitable for the roadway at the downtown area.

Description

technical field [0001] The invention relates to a method for smooth driving at an intersection and a road structure, belonging to the technical field of road traffic. Background technique [0002] With the increasing number of cars, road congestion is becoming more and more serious, especially at intersections. Vehicles going straight, turning left and turning around must cross other straight roads, so the driving speed is greatly delayed. . [0003] The existing road intersection structures mainly include the following types: [0004] 1. Plane intersection structure. The structure mainly relies on traffic lights or traffic police to direct vehicles to pass. It is suitable for road intersections with few running vehicles. When there are many vehicles, the waiting time is very long, which increases the fuel consumption and exhaust gas emission of the vehicle, has low efficiency, and causes great environmental pollution. [0005] 2. Turntable circular structure. Although...

AI Technical Summary

Problems solved by technology

This structure basically solves the unimpeded problem of most of the driving directions of the vehicle, but it still fails to solve the problem of turning around the vehicle, and it is not convenient for non-motorized vehicles to drive, and the cost of construction is very high; in addition, the biggest disadvantage is that it occupies a large area, so it is not suitable for urban intersection construction
