Road traffic system of Yongtong Interchange

Abstract

In order to solve the problem of traffic congestion at an intersection, the present patent provides a Yongtong overpass road traffic system at an intersection, which belongs to the field of road and bridge construction. It is composed of four branch bridge non-motorized vehicle lanes (22, 23, 24, 25) connected on both sides of the B-D main road overpass, an A-C main road connected to a motor vehicle underground passage (46-47, 48-49), a non-motorized vehicle underground passage (34-35, 36-37), and an entrance (31, 33) and exit (30, 32) of the non-motorized vehicle lane under the bridge, as well as a separation zone (42-43, 44-45) and a pedestrian overpass (99). The most significant feature is that the existing overpass can be slightly modified to have the same structure and function as the overpass in this case, without the need for traffic lights, motor vehicles, non-motor vehicles and pedestrians can go their own way in the four directions of straight, U-turn, left turn and right turn, without crossing and barrier-free passage, thus solving the problem of traffic congestion at the intersection.

Description

Technical Field

[0001] This patent relates to the field of road and bridge construction, and in particular to an overpass road traffic system at an intersection. Background Art

[0002] As people's living standards improve, the number of vehicles increases day by day. Using only traffic lights to control the level crossing roads can easily cause traffic congestion. The best solution is to build an overpass at the intersection. Although the existing overpass at the intersection can play a certain role in alleviating traffic congestion, there are generally problems such as incomplete functions, unreasonable structures, large floor space and high costs. So far, there is no ideal overpass that has been widely used. Most intersections still need traffic lights and traffic police to direct traffic, and vehicles and pedestrians still need to stop and wait. Traffic congestion is still a problem. Summary of the invention

[0003] In order to completely solve the problem of traffic congestion at the intersection, the Yongtong Interchange Road Traffic System provided by this patent has two technical solutions: Technical Solution 1 ( Figure 1 ) and its mirror image ( Figure 4 ) is suitable for small and medium-sized cities with fewer vehicles; Technical Solution 2 ( Figure 2 ) and its mirror image ( Figure 5 ) is suitable for large, medium and small cities with a large number of vehicles. The technical solution has a reasonable design structure, small footprint and low cost. The biggest feature is that it can make full use of the existing old overpass, which can be slightly modified to have the same structure and function as the newly built overpass in this case. Without traffic lights and traffic police command, motor vehicles, non-motor vehicles and pedestrians can go straight, turn around, turn left and turn right in four directions without crossing and barrier-free passage, which can completely solve the problem of traffic congestion at intersections.

Right turn: Turn right from the non-motorized vehicle lane (5) in the direction of A and follow the arrow to enter the non-motorized vehicle lane (5) in the direction of B to achieve the purpose of right turn; The method of using the non-motorized vehicle lane from direction C to other directions is the same as the method of using the non-motorized vehicle lane from direction A to other directions; How to use the lane for vehicles heading to other directions from direction B Go straight: Go straight from the B direction motorway (8) and motorway (9) in the direction of the arrow to the D direction motorway (8) and motorway (9), and you will reach the straight direction. U-turn: Go straight up the bridge from the motorway (9) in the B direction, turn right down the bridge and enter the motorway (29), continue going straight and turn right into the emergency lane (12) in the A direction, and then go to the road section with a median strip under the bridge (the median strip is between points 44 and 45), continue going straight and turn right into the motorway (28), then continue going in the direction of the arrow, enter the motorway (6) in the B direction and go straight to achieve the U-turn; or U-turn: Go straight up the bridge from the motorway (9) in the B direction, turn right down the bridge and enter the motorway (29), continue going straight and turn right into the emergency lane (12) in the A direction. There is a median strip under the bridge (the median strip is between points 44 and 45), continue going straight and turn right into the emergency lane (20), then go straight and merge to the left into the motorway (28), continue going in the direction of the arrow, enter the motorway (6) in the B direction and go straight. This completes the U-turn. Left turn: Go straight up the bridge from the motorway (9) in the B direction, turn right down the bridge and enter the motorway (29), continue going straight and turn right into the emergency lane (12) in the A direction.
