Problems solved by technology

[0003] The main cause of the traffic jam is that the traffic lights at each intersection turn back and stop driving. If the red light is changed every 60 seconds and the vehicle speed is 30km / h, then 16.5 vehicles are blocked in 30 seconds. , traveling 83m less, resulting in a 130-minute traffic jam at the Huangpu overpass in Guangzhou from 7:40 am to 9:50 am, and the traffic queue continued to Jida, Yuancun and other places; Vehicles, the 160-minute traffic jam from 7:30 am to 10:10 am has brought great pressure to urban traffic and brought great inconvenience to people's travel
[0004] In order to alleviate the pressure of traffic, the current method of urban traffic improvement is to erect several multi-storey overpass bridges at major arterial intersections, which can eliminate the red lights at intersections and realize smooth traffic in four directions at the same time, playing an important role in traffic flow regulation However, because the red light at the intersection of the inner street still plays a role uninterruptedly for 24 hours, the continuous rotation of urban vehicles is blocked within the red light, which cannot fundamentally solve the traffic jam problem; moreover, the existing overpass The architectural design mode of the building has large investment, multi-storey, long construction period, tall and majestic, and covers a large area, which seriously affects the city appearance and landscape vision, and brings unfavorable factors such as high-altitude noise. It is only suitable for construction on major arterial roads in urban areas The crossroads or the main traffic roads in the open areas of the suburbs are used as traffic hubs to guide the traffic flow in various regions, and it is not suitable to build intersections such as inner streets and roads during reconstruction.
[0005] In short, if the urban traffic jam situation is not improved, on the one hand, in the modern commercial and trade competition world where time is money, many industry and trade giants will definitely abandon the ears; on the other hand, fire trucks, ambulances, etc. Failure to arrive at the scene at the fastest speed will lead to tragedy, and if the traffic lights of the main roads in the city cannot be exempted, it will not be able to fundamentally solve the problem of traffic congestion and blockage

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] refer to figure 1 , figure 2 , according to a kind of improved metropolitan crossroad of the present invention sixteen directions unimpeded traffic hub system tunnel concave bridge is suitable for the crossroad that is formed by two bidirectional motor vehicle lanes intersecting each other, wherein the north-south lane is defined as the first Motor lane A, the east-west lane is defined as the second motor lane B. In addition, facing west, the one-way street on the right side of the second motor vehicle lane B is defined as the forward road B1 of the second motor vehicle lane, and the one-way lane on the left is defined as the reverse road B2 of the second motor vehicle lane; facing north, the right side of the first motor vehicle lane A The one-way lane is defined as the forward lane A1 of the first motor vehicle lane, and the one-wa...

Abstract

The invention discloses an improved tunnel concave bridge of a traffic hub system for keeping an intersection simultaneously smooth in sixteen directions. The tunnel concave bridge is applied to an intersection formed by two mutually-crossed two-way vehicle lanes. Arc-shaped auxiliary bridges are respectively arranged at the two sides in the length direction of an arch bridge and the two sides inthe length direction of an arch bridge concave lane, and auxiliary bridge concave lanes are arranged at the two sides in the length direction of the arch bridge concave road, wherein half the bridge deck at each end of the auxiliary bridges arranged at the two sides of the arch bridge is communicated with the lane of the arch bridge and the other half thereof is communicated with the lane on the ground; the two ends of the auxiliary bridges arranged at the two sides of the arch bridge concave lane are communicated with the ground lane between the arch bridge concave lane and the auxiliary bridge concave lane; and the auxiliary bridges are one-way traffic and are communicated with the ground lane so as to facilitate the vehicles to travel by changing the directions and making left or rightturns at random.

Description

technical field [0001] The invention relates to an improved tunnel-concave bridge of a traffic hub system at an urban crossroad, which belongs to the field of municipal traffic road construction. Background technique [0002] At present, with the acceleration of the global urbanization process and the popularization of vehicles, using cars instead of walking has improved the speed and efficiency of modern people's work, and cities generally have several or more than a dozen overpasses, which is very important for the transportation of the entire city. Undoubtedly, it is a drop in the bucket, the bottlenecks at the intersections in front of it - the red lights have blocked the winding car queues, the serious traffic jam situation in the metropolis has reached the point where it is necessary to implement comprehensive renovation (technical transformation) at the intersections, especially in Beijing In modern metropolises such as Guangzhou, Shanghai, Shenzhen, etc., where traff...
