Description
Technical Field
The invention relates to the technical field of road overpasses, in particular to an interchange type overpass.
Background
The interchange is a junction facility in an urban road traffic system and is important for realizing rapid conversion of road traffic, improving traffic operation efficiency and relieving traffic jam. In the built-up areas of large cities, the land for road construction is very short. On one hand, the available space for constructing the overpass is generally narrow and has limited land; on the other hand, in order to ensure that the interference of traffic noise to surrounding residents meets the requirement of environmental protection standards, the interchange ramps and the buildings need to be kept at a sufficient distance. Therefore, in the narrow and long zone of the urban built-up area, the conventional type of hub interchange is often difficult to arrange due to the dual constraints of land use limitation and noise pollution control.
For this reason, chinese patent document CN109853309A discloses a left-turn ramp roundabout type overpass, which includes a straight lane, a right-turn lane and a left-turn lane, wherein the right-turn lane adopts a direct connection type; the left-turn lane adopts a roundabout ramp with right-out and right-in, and is characterized in that left-turn traffic flow firstly turns right to be far away from the intersection and then roundly turns 180 degrees to realize left-turn. The scheme can be arranged by utilizing a long and narrow land, but has the defects of overlong left-turning lane detouring distance, low vehicle passing efficiency, large engineering scale and occupied area and high investment. Because the overpass is in a dumbbell shape, the widest part of the occupied land of the overpass is far away from the intersection of roads, so that the distance between the turn road at the outermost side and buildings at two sides of the roads is smaller, and the interference of traffic noise to surrounding residents is larger.
