Problems solved by technology

[0002] The existing design technology mainly uses the design technology of multi-level interchange, traffic light control and roundabout design technology or two or three combined design technologies to complete the vehicle driving order at the intersection. The disadvantage of the multi-level intersection design technology is the cost Expensive, complex intersection
The shortcoming of traffic light control design technology is the long waiting time of driving vehicles, which is also one of the important reasons for traffic jams.
The disadvantage of roundabout design technology is that it occupies a large area and affects straight vehicles

Embodiment 1

[0013] In attached drawing 1, there are main roads A and B connecting each other, and connecting with branch road D 1 、D 2 、D 3 、D 4 Connected, and then through the "C"-shaped cross-street bridge C 1 、C 2 Connected to form an intersection that can be driven around, forming a total of 28 diverging and merging points. Vehicles at each intersection realize turning as follows:

[0014] 1. When the vehicles on the branch road D1 arrive at the diversion point 21, there are six confluence points of 2, 28, 26, 8, 24, and 22 respectively, and the demand to drive out of the intersection is realized in this way:

[0015] (1) When arriving at the confluence point 2 from the diversion point 21, it can be changed from 21→13→2→

[0016] (2) When arriving at the confluence point 28 from the branch point 21, it can be changed from 21→13→2→1→12→11→20→28→

[0017] (3) When arriving at the confluence point 26 from the branch point 21, it can be changed from 21→13→2→1→12→11→10→9→18→26→

Embodiment 2

[0057] In attached drawing 2, there are main roads A and B connecting with each other and connecting with branch road D 1 、D 2 、D 3 、D 4 、D 5 、D 6 Connected, and then through the "C"-shaped cross-street bridge C 1 、C 2 Interconnected to form an intersection that can be driven around, forming a total of 28 diverging and merging points. Vehicles at each intersection turn as follows:

[0058]1. When the vehicles on the branch road D1 arrive at the diversion point 1, there are eight confluence points 8, 28, 26, 24, 15, 6, 4, and 2 respectively, and the demand to drive out of the intersection is realized in this way:

[0059] (1) From diversion point 1 to confluence point 8, it can be changed from 1→8→

[0060] (2) When arriving at the confluence point 28 from diversion point 1, it can be from 1→8→7→22→21→28→

[0061] (3) When arriving at the confluence point 26 from diversion point 1, it can be changed from 1→8→7→22→21→20→19→26→

[0062] (4) When arriving at the confluen...

Embodiment 3

[0078] In accompanying drawing 3, it is the plan view of Dashanzi Bridge in Chaoyang District. Wangjing Road and Jiuxian Bridge are the main roads, and a "C"-shaped cross-street bridge or underground corridor will be built on each of the main roads. A new high-speed bridge across Wangjing Road will be built on Jingshun Road. With other facilities unchanged, there will be no red light control intersections. A total of 26 diverging and merging points will be formed, including 9 entering and 9 exiting intersections.

[0079] The following is an example when a vehicle on Jingshun Road arrives at the diversion point 21. It needs to have 9 intersection options, which are described as follows:

[0080] (1) From diversion point 21 to the entrance and exit of the airport expressway, vehicles entering the airport expressway can turn right from 21→23→4→3→.

[0081] (2) Vehicles arriving at Jiuxianqiao Road from diversion point 21 can go straight from 21→23→4→3→2→1→.

[0082] (3) Vehicl...

Abstract

The invention discloses design technique for a no-red light encircling type crossroad. By utilizing the design technique, red lights for controlling traffic are not required to be arranged on crossroads of roads. In the invention, two C-shaped pedestrian bridges or pedestrian corridors are connected with both sides of a road so as to form an encircling traffic route. Compared with the prior design technique, the design technique of the invention has the advantages of simple structure, low cost, no conflict points, no red light control, smooth traffic and no space restriction of road junctions.

Description

technical field [0001] The invention relates to a design technology of a highway intersection, more specifically the invention relates to a design technology of a highway multi-level intersection with no conflict point and no red light control. Background technique [0002] The existing design technology mainly uses the design technology of multi-level interchange, traffic light control and roundabout design technology or two or three combined design technologies to complete the vehicle driving order at the intersection. The disadvantage of the multi-level intersection design technology is the cost Expensive, complex intersection. The disadvantage of traffic light control design technology is that the waiting time of vehicles is long, which is also one of the important reasons for traffic jams. The disadvantage of roundabout design technology is that it occupies a large area and affects straight vehicles. Contents of the invention [0003] The purpose of the present inve...
