Description
Technical field
The invention belongs to viaduct road technology fields, and in particular to a kind of people's vehicle separate type bilayer island overpass.
Background technique
Since car ownership continues to increase, often occur traffic delay, congestion feelings at the more crossroad of vehicle
Condition.Locate at the parting of the ways, the demand of the oriented multiple directions conversion of the road wagon flow of both direction seriously affects wagon flow at crossing
Traffic efficiency, cause the congestion of entire road persistently to be aggravated, in addition, people's vehicle does not separate, traffic lights lamp cap or lamp tail
Vehicle is easy to appear phenomenon by force, and some potential safety problems is caused when passing through crossroad to the pedestrian of street crossing.
The handling capacity at crossing can not solve in a plane, and existing road traffic mostly uses intercommunication multilevel traffic
Bridge and other viaducts that congestion is effectively relieved solve, but the occupied area that intercommunication three-dimensional access bridge and other viaducts have
Greatly, some numbers of plies are more, and the gradient is big, and some numbers of plies are few, but function is not perfect, and somebody's vehicle does not separate, and structure is complicated, cost
Height, split point and junction of two streams are more, and some even has intertwined point.For Simple flyover in the prior art, some be cannot achieve
It turns around at crossing.
Summary of the invention
In order to overcome the shortcomings of and improve in background technique, it is an object of the invention to propose that a kind of people's vehicle separate type is double-deck
Island overpass solves traffic delay at crossroad existing in the prior art, congestion, traffic efficiency difference and people Che Bufen
From there is certain security risk.It is small to realize viaduct occupied area, the number of plies is two layers few, the gradient is small, perfect in shape and function, people
The purpose of vehicle separation, structure is simple, and low cost, split point is few with junction of two streams, no intertwined point, and the safety for reducing vehicles or pedestrians is hidden
Suffer from, realizes and turn around at multiple types vehicle intersection.
To achieve the above object, people's vehicle separate type bilayer island overpass of the invention includes four mutually symmetrical with right-hand rotations
