Abstract
The present invention discloses a crossroad left-turning overpass, and relates to the field of interconnection of three-dimensional roads. In order to alleviate traffic congestion phenomena in cities and improve the passage efficiency of crossroads, the present invention provides a novel left-turning overpass so as to eliminate the at-grade intersection of the left-turning line and the straight-driving line of a crossroad. The technical scheme for solving the technical problem in the present invention is that a left-turning bridge surface 4.5 m away from the ground is arranged on the center of a crossroad, and is connected to the left-turning lanes of each intersection through ramps, all left-turning are performed through the bridge surface, traffic signal lights the same as the straight driving on the ground are used to control during the passage, and the two left-turning in opposite directions are performed every green lamp lighting and do not interfere with each other. With the technical scheme of the present invention, the passage efficiency of the crossroad can be increased by about one time, the crossroad left-turning overpass is suitable for the large-volume crossroads or three-way intersections, and the new land is not occupied, the engineering quantity is small and the coat is low when the crossroad left-turning overpass is built on the existing road.
Description
Technical field
The present invention relates to overpass is connected with each other field, more particularly to a kind of turning left at crossroad viaduct.
Background technology
Traffic congestion is global problem in city, and the especially traffic efficiency in intersection is relatively low, with two-way six car
As a example by road crossroad, car lane four corners of the world direction respectively have straight trip, turn right, each 3 transit routes of turning left, totally 12 pass through
Route.It is unrestricted wherein to turn right, and totally 8 transit routes of turning left and keep straight on need to pass through by traffic lights control wheel stream.It is each
Secondary green light allows 2 symmetrical transit routes to be open to traffic, a cycle No. totally 4 green lights.This 8 transit routes had at 3/4 time
It is less efficient in the red light phase that no through traffic.Simultaneously most of crossing space all relative narrowness in city, do not possess construction big
The condition of scale viaduct.
The content of the invention
In order to reduce the time that intersection waits red light, the efficiency of intersection vehicle pass-through is improved, the present invention is eliminated
Straight and turning left is curved to be interfered, and makes the left-hand bend and straight trip at same crossing can while carrying out.By taking crossroad as an example, will
No. 4 green lights in a cycle（Laterally straight trip-horizontal left-hand bend-vertical straight trip-vertical left-hand bend）It has been reduced to No. 2 green lights
（Laterally straight trip, horizontal left-hand bend-vertical straight trip, vertical left-hand bend）, the traffic efficiency in the unit interval is doubled, front
The square vehicle stand-by period is reduced to most 1 red light by most 3 red lights.
The technical solution adopted for the present invention to solve the technical problems is：At the parting of the ways central authorities set up one it is above ground level
More than 4.5 meters of left-hand bend bridge floor, bridge floor is connected with the left turn lane at each crossing by ramp, and the left-hand rotation at each crossing bend into
Mouth track and left-hand bend exit lane are adjacent, can be merged into a ramp.Laterally during green light, laterally two-way through vehicles pass through
Floor traffic, bridge passes through on the curved vehicle of horizontal Dual Left Turn；Laterally green light terminates, during longitudinal green light, the two-way through vehicles in longitudinal direction
By floor traffic, bridge passes through on the curved vehicle of longitudinal Dual Left Turn；The right-hand bend in 4 directions is unrestricted；Green time institute twice
Directive vehicle all passes through once.
The present invention is a kind of turning left at crossroad viaduct, is mainly made up of left-hand bend bridge floor, ramp, also including hurdle
Bar, column or bridge pier, pile foundation etc..Turn left to import and export the extended line in track at each crossing in the bridge floor center of left-hand bend bridge floor
Intersection region, and a track or more is widened to surrounding, bridge floor is suitably prolonging with ramp connecting portion depending on the big I of radius of turn
It is long.Supported using column or bridge pier under bridge, column or bridge pier are arranged on outside Through Lane.To increase radius of turn, turn left
Track waits line to may be provided on ramp.The side of bridge floor surrounding the cat's whisker mouth, one up gradient of correspondence and a gug, such as
Fruit up gradient and gug spacing are less, and ramp can merge；If spacing is larger, can merge at close bridge floor, with fully profit
With space and reduces cost, and increase radius of turn.Hill gradient should be suitable, and be neither above standard the upper limit, also as far as possible big, with
Save space and reduce construction costs.The main support in bridge floor and ramp is stood all using steel construction or reinforced concrete structure
Post or bridge pier adopt pile foundation load-bearing.Steel construction is preferentially adopted, efficiency of construction is improved.Steel construction forms little framework as far as possible.
Guardrail adopts anti-collision structure around bridge floor and ramp, prevents vehicle operating error from rushing open guardrail and drops under bridge.
Bridge floor and ramp arrange drainage pipeline and street lamp.
Artificial light is adopted under bridge.
Sufficiently high traffic lights are set in turning bridge floor overcentre, the various vehicle vehicles of all directions is seen
Signal lamp.
The invention has the beneficial effects as follows：The vehicle pass-through efficiency of intersection is significantly improved, both increased in the unit interval
Throughput, decrease the vehicle stand-by period；Space availability ratio is high, and space is big on bridge, and barrier is few, and various types of vehicles has
Enough turning spaces；Take up room little, impact is not produced on the region outside road；Quantities is little, cost relative moderate.

Specific embodiment
Embodiment 1
The shape left turning overpass of crossroad, four crossings have the ramp that is merged into by a up gradient and gug with
Shape left turning overpass bridge floor UNICOM.Laterally during green light, curved totally 4 routes of above-below direction straight and turning left are simultaneously current；Longitudinal direction is green
During lamp, curved totally 4 routes of left and right directions straight and turning left are simultaneously current.Turn right unrestricted, at any time P Passable.Two green
Lamp can make all transit routes current once.
Embodiment 2
The shape left turning overpass in T-shaped road junction, left side crossing only has a gug, and right side crossing only has a up gradient, downside
There are up gradient and gug in crossing.Laterally keep straight on and respectively bend to right and be unrestricted, pass through at any time.Only right-hand rotation bottom left turn and
Under turn left left-hand rotation crook arrange traffic lights, pass through in turn.
