Human-car separation type double-layer overpass bridge

Abstract

The invention provides a human-car separation type double-layer overpass bridge, belongs to the technical field of overpass roads, and aims to solve the problems that traffic retention, congestion, poor traffic efficiency and the existence of certain safety hazards caused by no separating human and vehicles at the intersections exist in the prior art. The human-car separation type double-layer overpass bridge comprises four right steering bridges symmetrically arranged, four left steering bridges symmetrically arranged and two spatially intersecting two-way straight bridges. One two-way straight bridge is located on a ground layer and the other two-way straight bridge is located on an upper interchange layer according to the intersection position. A right turn lane of each intersection communicates with at least one reverse straight lane located on the outer side of a right adjacent intersection at the right side through one right steering bridge; a forward straight lane of each intersection communicates with at least one reverse straight lane in the middle of the opposite intersection through a forward straight bridge in one two-way straight bridge; and the left turn lane of eachintersection communicates with at least one reverse straight lane located on the inner side of an adjacent intersection at the left side through one left steering bridge.

Description

technical field [0001] The invention belongs to the technical field of overpasses and roads, and in particular relates to a double-layer overpass with separation of people and vehicles. Background technique [0002] Due to the continuous increase in car ownership, traffic jams and congestion often occur at intersections with more vehicles. At the intersection, the road traffic flow in both directions has the demand to switch to multiple directions, which seriously affects the traffic efficiency of the traffic flow at the intersection, resulting in the continuous aggravation of the congestion of the entire road. In addition, people and vehicles are not separated. Vehicles at the rear are prone to forcible phenomena, causing certain safety hazards for pedestrians crossing the street when passing through the intersection. [0003] The passing capacity of the intersection cannot be solved in one plane. The current road traffic is mostly solved by the interchangeable three-dimen...
