a simple overpass

Abstract

A novel interchange scheme is disclosed. An upwards-straddle-type interchange is built above a main road; a vehicle turning-around lane and a pedestrian passageway are arranged on the lower portions of the two sides of the interchange correspondingly; vehicle turning-around lanes are arranged on the two sides of the central line of a ground road; a roundabout and a turning-around lane are arrangedin the middle of a road junction; and a straight lane is arranged on the outer side of the turning-around lane. After the novel interchange scheme is built,, straight passing vehicles on the main road pass through the road junction along a straight passageway on the upper portion of the interchange; straight passing vehicles on the ground road pass through the road junction through a straight passageway on the lower portion of the interchange, and the straight passing vehicles do not cross with one another at the road junction; rightwards-turning vehicles in all the directions directly turn right through a rightwards-turning lane and then pass through the road junction; and leftwards-turning vehicles turns around through the adjacent road junctions to turn left. The turning-around lane atthe road junction is arranged for the leftwards-turning vehicles at the adjacent road junctions, and thus the problem of crossing of the leftwards-turning vehicles is solved. By building the simple overline interchange, mutual communicating of the vehicles in all the directions of the road junctions is achieved, road interchange in the urban center area without demolition or with little demolition is achieved, and the urban space and project investment are saved.

Description

technical field [0001] This design involves the design of a simple overpass for urban traffic. Specifically, it is to set up a U-turn roundabout in the middle of the main road intersection on the ground, set up a U-turn lane on both sides of the middle of the road, and set up a U-turn lane under the overpass, and use the method of combining the U-turn in the middle of the intersection with the U-turn at the adjacent intersection. Solve the crossing problem of left-turning vehicles and realize the simple interchange. Background technique [0002] With the development of the modern automobile industry, the problem of traffic congestion has become a chronic disease of urban development, which brings great inconvenience to people's life and travel. Many cities have adopted methods such as building urban viaducts, urban expressways, or building interchange bridges at major intersections, but it is difficult to promote them in small and medium-sized cities due to the large investm...

Problems solved by technology

Many cities have adopted methods such as building urban viaducts, urban expressways, or building interchanges at major intersections, but it is difficult to promote them in small and medium-sized cities due to the large investment

Especially in the center of the city or the old city, even if an interchange bridge is built, it will be difficult to popularize it due to the large area required, the large amount of demolition work required, and the impact on the existing surrounding commercial atmosphere.
