Description

Technical Field

[0001] This invention relates to the field of interchange technology, and more particularly to an eight-way interchange. Background Technology

[0002] An overpass, also known as a grade-separated interchange, is a modern bridge built at the intersection of two or more roads, with multiple levels that allow for independent traffic flow in different directions. Due to its high construction cost, it is usually only built at highway interchanges, urban arterial roads, or expressways. Its main function is to allow vehicles to travel smoothly in all directions without being controlled by traffic lights at intersections.

[0003] Existing road intersections typically address multi-way traffic by constructing grade-separated interchanges. These interchanges, often resembling cloverleaf structures, are multi-level or multi-level, involving large areas, numerous levels, significant construction costs, and generally ensuring unobstructed straight-through traffic on main roads. However, they often result in straight-through vehicles from other directions merging with turning vehicles, and some even include traffic lights. These solutions fail to adequately address the issues of multi-way interchanges, creating numerous weaving points, slow-moving traffic, congestion, and overlapping routes, increasing the risk of accidents. First-time users often struggle to navigate the interchanges and may find themselves unable to find their exits. Therefore, we propose an eight-way interchange to address these problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing interchanges, which generally have large land area, many layers, large engineering volume, high cost, are prone to congestion, cause vehicle traffic routes to intersect, easily lead to traffic accidents, and make it difficult for first-time users to understand the road layout and may not be able to find the exit. Therefore, this invention proposes an eight-way interchange.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An eight-way interchange includes one, three, two, four, five, six, seven, and eight-way roads. The one and three roads, and the two and four roads, form a cross-shaped interchange.

The two first upper-level auxiliary bridges are connected to both sides of the upper-level straight-ahead two-way lanes. The lower-level straight-ahead two-way lane includes two first lower-level auxiliary lanes and two first lower-level up-turn left-turn auxiliary lanes. The first lower-level up-turn left-turn auxiliary lanes are connected to the inner sides of the two first lower-level auxiliary lanes and the two first upper-level auxiliary bridges. The two first upper-level down-turn left-turn auxiliary lanes are connected to the two first upper-level auxiliary bridges and the two first lower-level auxiliary lanes.

[0016] 5. In this invention, by setting up signs and directional arrows and playing traffic animations on a display screen, users who are entering the overpass for the first time can quickly and accurately find the exit, so as not to get stuck on the overpass and cause traffic congestion.

[0017] This invention has a simple structure. Vehicles can go straight, turn left, turn right, and make U-turns by passing through the upper two-way straight lane, the lower two-way straight lane, and eight right-turn lanes. This achieves full interconnection of lanes in all 16 directions at the eight-way intersection, and eliminates the need for traffic lights. This greatly improves traffic efficiency, ensures smooth vehicle traffic, and reduces the probability of traffic accidents. Attached Figure Description

For vehicles making a U-turn, the vehicles first enter the first upper-level auxiliary bridge 1, then enter the first upper-level downhill left-turn auxiliary lane 3, then enter the first lower-level auxiliary lane 2, and then pass through the first lower-level uphill left-turn auxiliary lane 4 to enter the first upper-level auxiliary bridge 1 to go straight and complete the U-turn. Vehicles going straight at the two-way intersection 20 and the four-way intersection 40 complete their straight-through journey via the lower-level straight-through two-way lanes.

Six-way road 60 enters the first upper-level auxiliary bridge 1 via the one-way inward straight lane 6 of the auxiliary bridge, and then enters the virtual roundabout via the upper-level downward left-turn auxiliary lane to complete any direction turn. Other vehicles enter six-way road 60 via the one-way outward straight lane 8 of the auxiliary lane. Eight-way road 80 enters the first upper-level auxiliary bridge 1 via the one-way inward straight lane 6 of the auxiliary bridge, and then enters the virtual roundabout via the upper-level downward left-turn auxiliary lane to complete any direction turn.

First, enter the second upper-level auxiliary bridge 1003, pass through the second upper-level downhill left-turn auxiliary road 1005, then enter the second lower-level auxiliary road 1004, follow the second lower-level uphill left-turn auxiliary road 1006 to enter the second upper-level auxiliary bridge 1003, then follow the second upper-level downhill left-turn auxiliary road 1005 to enter the second lower-level auxiliary road 1004, then proceed straight to complete the right turn; turn 270 degrees to complete the right turn. Vehicles on the upper-level one-way auxiliary road 1007 proceed straight... Enter the second upper-level auxiliary bridge 1003, then enter the virtual roundabout to make any direction turn. Vehicles on the lower level should proceed straight along the lower-level two-way straight lane 1002. Alternatively, first pass through the second lower-level auxiliary road 1004 to enter the second lower-level uphill left-turn auxiliary road 1006, then enter the second upper-level auxiliary bridge 1003 to complete the left turn (only a 90-degree turn is needed). Or, first enter the second lower-level auxiliary road 1004, pass through the second lower-level uphill left-turn auxiliary road 1006, and then enter the second upper-level auxiliary bridge 1003. From the second upper-level downhill left-turn auxiliary road 1005, enter the second lower-level auxiliary road 1004, then proceed straight to complete the U-turn (only a 180-degree turn is needed). Alternatively, first pass through the second lower-level auxiliary road 1004 to enter the second lower-level uphill left-turn auxiliary road 1006, then enter the second upper-level auxiliary bridge 1003.
