Title:
CROSS-SHAPED OVERPASS
Document Type and Number:
WIPO Patent Application WO/2018/085960
Kind Code:
A1
Abstract:
An overpass comprises four layers. The upper layer is though-traffic lanes of a longitudinal road, the middle layer comprises all right-turn traffic lanes and traffic lanes of a crossing road, a ground layer is lanes for pedestrians and non-motorized vehicles, and the lower layer comprises all left-turn traffic lanes. After a left-turn traffic lane goes down to a required depth, the left-turn traffic lane crosses with a traffic lane that comes upwards from a left turn in a perpendicular direction, under the ground and on the ground, and then the left-turn traffic lane and the traffic lane that comes upwards from the left turn in the perpendicular direction respectively change their lands; the left-turn traffic lane that comes upwards passes through the central line on the right side of the left-turn traffic lane, and then goes out; and the left-turn traffic lane that that goes downwards away crosses the central line of a road on the left side under the ground, continues to extend to the front of the central line of a crossing road and makes a turn, and then climbs upwards to the road surface, then changes the traffic road, passes through the central line of the road on the right side, and then goes out. The width of the overpass is proximately equal to that of a road, and the floor area of the overpass is greatly reduced, thereby reducing construction price and improving the trafficability.
