Description

Technical Field

[0001] This invention belongs to the field of road traffic facilities technology, specifically relating to a traffic system that achieves traffic light-free control through a layered three-dimensional design. Background Technology

[0002] In urban traffic, traffic light control at intersections is one of the main factors causing traffic congestion and long waiting times. Furthermore, the intersection of traffic flows at traffic light intersections increases the risk of traffic accidents. While existing grade-separated transportation infrastructure (such as traditional overpasses) can achieve partial separation of traffic flow, there is still surface intersection of turning traffic, making it impossible to completely eliminate reliance on traffic lights and limiting improvements in traffic efficiency. Therefore, there is an urgent need for a traffic system that can achieve complete grade-separation of traffic flow in all directions without the need for traffic light control, in order to effectively solve intersection congestion and safety problems. Summary of the Invention

[0003] Purpose of the invention This invention aims to provide a traffic light-free three-dimensional transportation system. Through a layered three-dimensional design consisting of an elevated bridge layer, a ground layer, and an underground passage layer, vehicles traveling in different directions can travel on different layers, eliminating traffic lights at intersections, significantly improving traffic efficiency, and reducing traffic congestion and accident rates.

[0004] Technical solution The traffic light-free three-dimensional traffic system of the present invention includes a vertically layered elevated bridge layer, a ground layer, and an underground passage layer. Vehicles can move between layers via ramps and underground passage entrances and exits. The specific structure is as follows: 1. Elevated bridge level The system includes at least two parallel elevated roads for vehicles traveling straight in a specific direction. For example, it includes an elevated road for vehicle direction f and an elevated road for vehicle direction 4. The elevated roads have entrances and exits that connect to ground-level roads (such as a, b, c, 1, 2, 3, 5, 6, d, e, etc.), allowing vehicles to switch between the elevated bridge level and the ground level via on-ramps and off-ramps.

[0005] 2. Ground floor The road surface is designed to allow vehicles to travel straight and make specific turns. Green belts separate traffic flows in different directions to avoid interference between opposing or same-direction traffic. Pedestrian overpasses are also provided to allow pedestrians to safely cross the road surface. The pedestrian overpasses connect to the ground-level sidewalks to avoid areas where vehicles are traveling.

[0006] 3. Underground passage level Including left-turn underpasses and straight-through underpasses: - Left-turn underground passage: for vehicles to turn left, with entrances and exits connecting to the ground level, allowing vehicles to enter the underground passage level from the ground level or exit from the underground passage level to the ground level; - Straight-through underground passage: for vehicles to pass straight through. It can be set up in layers or side by side with the left-turn underground passage, and it also has corresponding entrances and exits.

[0007] Beneficial effects 1. Traffic light-free passage: Vehicles traveling in different directions travel on different levels, eliminating traffic lights at intersections, greatly improving traffic efficiency and avoiding vehicle waiting time.

[0008] 2. Traffic flow separation, safe and reliable: Through layered design, traffic flows in different directions do not intersect at level, reducing the incidence of traffic accidents.

[0009] 3. Pedestrian safety: The construction of pedestrian overpasses completely separates pedestrians from vehicles, ensuring pedestrian safety when crossing the street; green belts not only separate traffic flow but also enhance the aesthetics of the road.

[0010] 4. High space utilization: The three-dimensional layered design makes full use of vertical space, adapts to the complex traffic needs of the city, and alleviates the pressure on ground traffic. Attached Figure Description

[0016] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Each layer of structure and traffic flow direction 1. Elevated bridge level ( Figure 2 ) The elevated bridge level features two parallel elevated roads, one for vehicles traveling in direction f and the other in direction 4, allowing them to proceed straight through. For example, a vehicle traveling in direction f enters the elevated road in direction f from the ground-level entrance / exit, proceeds straight through the intersection, and exits at the corresponding exit back to the ground level. Similarly, a vehicle traveling in direction 4 proceeds straight through the intersection on the elevated road in direction 4. The elevated bridge level also includes ramps connecting to ground-level roads a, b, c, 1, 2, 3, 5, 6, d, and e, facilitating vehicle movement between the upper and lower levels.

[0018] 2. Ground floor ( Figure 3 ) The ground-level roads allow vehicles traveling in directions d and e to proceed straight, as well as some vehicles to turn. Green belts separate opposing or unidirectional traffic flows; for example, a green belt is placed in the middle of the ground-level road to separate vehicles traveling in opposite directions. Pedestrian overpasses cross the ground-level roads, connecting the sidewalks on both sides, allowing pedestrians to cross the street safely. The ground-level also has entrances and exits connecting to the underground passage level, allowing vehicles to enter or exit the underground passage level.

[0019] 3. Underground passage level ( Figure 4 ) The left-turn underpass on the underground passage level is for vehicles making left turns. For example, a vehicle heading in direction 'a' enters the left-turn underpass from the ground-level entrance / exit, turns left, and exits from the corresponding exit back to the ground level. The straight-through underpass is for vehicles heading in directions 'c', '1', etc., to proceed straight through the intersection. Vehicles enter the straight-through underpass from the ground level, proceed straight through the intersection, and exit from the exit back to the ground level. The left-turn and straight-through underpasses are spatially separated to avoid traffic flow overlap.

[0020] Typical traffic flow example - Vehicles in directions f and 4: proceed straight through the intersection on the corresponding elevated road at the elevated level without any intersection conflict.

[0021] - Vehicles heading in directions d and e: proceed straight through the intersection on the ground level road, ensuring traffic order and pedestrian safety through green belts and pedestrian overpasses.

[0022] - Left-turning vehicles in direction a: Left-turning through the underground passage level, completely separated from traffic flow in other directions.

[0023] - Vehicles in directions c and 1: Proceed straight through the underground passage on the underground level to cross the intersection and avoid crossing with traffic on the ground level.

[0024] Through the above-mentioned layered design, vehicles in each direction (a, b, c, 1, 2, 3, 4, 5, 6, d, e, f) travel on the elevated bridge level, the ground level, and the underground passage level respectively, without any at-grade intersections, achieving efficient and safe passage without the need for traffic light control.

[0025] The traffic light-free three-dimensional traffic system of the present invention effectively solves the congestion and safety problems caused by traditional traffic lights at intersections through a vertically layered three-dimensional design. It has significant effects on improving traffic efficiency and safety, and is suitable for traffic renovation and new construction projects at major urban intersections.
