An urban crossroad structure

Abstract

An urban intersection structure, wherein a first trunk road (1) and a second trunk road (2) form a central platform (3) at the intersection, and the first trunk road (1) is provided with an underground passage through the central platform (3). The low-slung tunnel (4) leads to the over-the-line turning tunnel (5) from the low-slung tunnel (4). The low tunnel is divided into two surface lanes (7, 8) with opposite driving directions for large vehicles, and the two surface lanes (7, 8) are connected on the central platform (3) to form a U-turn lane (9, 10) ), the two U-turn lanes (9, 10) are located on the left and right sides of the straight lane occupied by the second arterial road (2) on the central platform (3). The urban intersection structure utilizes low-slung tunnels (4), cross-line turning tunnels (5) and central platform (3) to divert large and small vehicles and vehicles in all directions.

Description

technical field [0001] The invention relates to urban road structures, especially urban crossroad structures. Background technique [0002] What is good traffic? Interchange Pass is the best transportation! At present, urban intersections mainly adopt road structures such as plane intersections, roundabouts, viaducts, multi-storey overpasses, and high-clearance tunnels. However, these existing road structures have defects of one kind or another, and cannot effectively solve the problem of traffic jams in cities. For example, for intersections that use level intersections, traffic lights need to be used to control the passage of each lane in turn, and the vehicles are gathered together before they are released, resulting in serious congestion at the intersection, and drivers rushing to rush to the red in order to compete for time. lights, it is easy to cause accidents such as rear-end collisions or lane-changing collisions, resulting in serious losses such as personal inju...

However, these existing road structures have defects of one kind or another, and cannot effectively solve the problem of traffic jams in cities

For example, for intersections that use level intersections, traffic lights need to be used to control the passage of each lane in turn, and the vehicles are gathered together before they are released, resulting in serious congestion at the intersection, and drivers rushing to rush to the red in order to compete for time. lights, it is easy to cause accidents such as rear-end collisions or lane-changing collisions, resulting in serious losses such as personal injuries and car damage; There are above-mentioned defects; For the intersections that adopt viaducts and multi-storey overpasses, the approach bridges at both ends in the middle of the bridge are longer, and there are many piers. years, it takes up a lot of valuable land resources in the city, and the construction of elevated overpasses in the bustling urban areas will reduce the commercial value of the surrounding areas. It is also for these reasons that it is impossible to build most of the intersections into elevated roads in a city. Overpasses, resulting in a bottleneck effect, resulting in more serious traffic congestion at the next intersection after passing the elevated overpass; for intersections with high-clearance tunnels, in order to allow large vehicles to pass through the tunnel, the clearance of the tunnel must be made higher , usually up to 5 meters, resulting in a large amount of excavation, long construction time, and high cost. Because of these reasons, it is impossible to build most intersections into high-clearance tunnels in a city. Vehicles pass through a high After clearing the tunnel, it will also encounter congestion, which will also cause a bottleneck effect
