Crossroad flyover

Abstract

The invention provides a crossroad flyover, and relates to the field of traffic of crossroads and T-junctions of cities. The crossroad flyover is composed of an AB direction road and a CD direction road and further comprises an AD flyover, a BC flyover, a CA flyover and a DB flyover which are erected above the CD direction path. The AD flyover and the DB flyover are intersected with each other; the BC flyover and the CA flyover are intersected with each other; the AD flyover is in the D direction that the A side turns left to enter the CD direction road, the BC flyover is in the C direction that the B side turns left to enter the CD direction road, the CA flyover is in the A direction that the C side turns left to enter the AB direction road, and the DB flyover is in the B direction that the D side turns left to enter the AB direction road. By means of the design, vehicles in all directions can pass through at the same time without mutual interference, the route is clear, traffic lightwaiting time is saved, the passing rate is increased, the time of the vehicles on the road is shortened, and the energy waste can be reduced.

Description

technical field [0001] The invention relates to the traffic fields of crossroads and T-junctions in various cities, in particular to an overpass at a crossroad. Background technique [0002] As the number of vehicles on the road continues to increase, the traffic pressure is also increasing, and traffic congestion is becoming more and more serious. Although the government is constantly improving the transportation system, such as vigorously developing subways and high-speed rail, it still cannot solve the road congestion caused by the increase in the number of private cars, and the traffic light restrictions make the roads with limited traffic capacity even more overwhelmed.

Problems solved by technology

Although the government is constantly improving the transportation system, such as vigorously developing subways and high-speed rail, it still cannot solve the road congestion caused by the increase in the number of private cars, and the traffic light restrictions make the roads with limited traffic capacity even more overwhelmed

[0003] At present, the country is not deeply aware of the restrictions brought by traffic lights at intersections to the traffic system. The existing solutions are to add culverts at intersections or build intersections into roundabouts

But it turns out that the effect is not good. The culvert only guarantees the uninterrupted passage of straight vehicles driving in the culvert, but the vehicles on the ground still have to be controlled by traffic lights. The roundabout covers a large area and when it is multiple roads Involves a lot of merging and weaving, so the efficiency gain is small, and the traffic of pedestrians and bicycles is also not considered

However, the population density in foreign countries is not large, and the traffic pressure is relatively small compared with domestic ones, so there are few studies
