An urban crossroad structure

Abstract

Disclosed is a municipal crossroads structure, comprising a first artery (1) and a second artery (2) of a crossroads interchange, wherein the first artery (1) and the second artery (2) form a central platform (3) at the interchange, the first artery (1) is provided with a low tunnel (4) passing underneath the central platform (3), the height of vehicles passing through the low tunnel (4) being no less than 2 metres and no more than 3 metres. The surface lane of the first artery (1) is separated by the low tunnel (4) into left and right surface lanes (5, 6) for travel in opposite directions and can be used by large vehicles. The two surface lanes (5, 6) connect on the central platform (3) to form two lanes for turning around (7, 8) which have opposite turning directions and can be used for the turning around of large vehicles, the lanes for turning around (7, 8) being located to the left and right of a straight-on lane of the second artery (2) on the central platform (3). The municipal crossroads structure uses a low tunnel (4) and a central platform (3) to enable split-flow for small and large vehicles and vehicles travelling in different directions, such that a large volume of small automobiles will meet no resistance when travelling, and traffic is smooth across the whole crossroads. In addition, a half-sunk / half-elevated type tunnel structure is used for the low tunnel (4), making construction easier and resource consumption less.

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
