Abstract
The invention discloses a traffic light-free viaduct for a three-way intersection, which is a traffic light-free, simple, convenient and direct fast passage of the three-way intersection. The traffic light-free viaduct adopts a single-layer overhead mode, occupies less land, and has simple construction and low cost. Pedestrians and vehicles take their own roads, have quick pass and clear lines, and do not need to change lanes. The viaduct is suitable for various three-way intersections with more than two lanes. The invention erects upbridge and downbridge lanes on an A lane of the three-way intersection for the pass of left-turning and right-turning vehicles. Upbridge, downbridge and U-shaped overhead passages are erected on B and C lanes of the three-way intersection for the pass of straight-through, left-turning and right-turning vehicles, and the U-shaped overhead passages are used specially for the pass of the left-turning vehicles. Turnaround vehicles on the A, B and C lanes can directly turn around on ground turnaround lanes. The pedestrians can directly pass on ground roads of the intersection.
Description
Technical field:
What the present invention relates to is a kind of traffic lights that need not in the use of the fork in the road of highway, and pedestrian and vehicle can straightway fork in the road viaduct.
Background technology:
At present, existing fork in the road viaduct exists following shortcoming:
1, people's car mixes row, needs the traffic lights commander;
2, the viaduct level is many, complex circuit, and floor space is big, and difficulty of construction is big, and very inconvenience of walk;
When 3, vehicle travels on viaduct, exist lane change or and the situation in road, it is current fast to hinder vehicle, and easily causes traffic accident.
Summary of the invention:
The present invention is the current fast viaduct in a kind of easy, direct fork in the road.Use all can be set up in above all kinds of forks in the road, two tracks.
What the present invention adopted is the overhead mode of individual layer, can directly be erected on original road of three directions in fork in the road.(the A road in the accompanying drawing 1) sets up Shang Qiao and Xia Qiao track on the road that vehicle can not be kept straight in road junction, for the vehicle pass-through of left and right commentaries on classics.(B, C road in the accompanying drawing 1) sets up Shang Qiao, following bridge and U type overhead passage way on the two road that vehicle can be kept straight in road junction, and for the vehicle pass-through of craspedodrome and left and right commentaries on classics, it is current that U type overhead passage way is specialized in left turning vehicle.
This viaduct line clear, simple in structure, vehicle is taken their own roads, need not lane change.The vehicle that needs to keep straight on or turn right only needs to get final product by the travel direction Shang Qiao that indicates, following bridge, and vehicle pass-through is convenient and swift.Bridge gets final product the vehicle that need turn left under the revolution of U type overhead passage way by entering after overhead on the travel direction of indicating.Need the vehicle of tune only to need directly to reverse end for end to get final product in tune track, ground.The pedestrian can have free passage on the ground level road at crossing.
This fork in the road viaduct has the following advantages:
1, the present invention puts pedestrian's the right of way in the first place, and the mode of passing through is the most easily offered the pedestrian, and the pedestrian can have free passage on the ground level road of crossing, does not again worry safety problem.And the toys that can not see traffic lights have also had a life passage.
What 2, this viaduct adopted is the overhead mode of individual layer, and has utilized original road surface to set up, and takes up an area of for a short time, and construction simply, and is applied widely.
3, this viaduct need not be commanded by traffic lights, line clear, and vehicle is taken their own roads, and need not lane change, and the driver drives current simple and convenient, very clear.

Fig. 2: traffic light-free viaduct for three-way intersection vertical view
The specific embodiment:
The present invention adopts individual layer viaduct mode, and the occupation of land scope is little, and construction is simple, can utilize existing road to set up, and above all kinds of forks in the road, two tracks all are suitable for.Following examples will the invention will be further described in conjunction with the accompanying drawings.
Can directly be erected at referring to accompanying drawing 1, this fork in the road viaduct on three directions of road cross, on the A road, be provided with up-run lane and descending track, on B, C road, be provided with up, descending track and U type overhead passage way.The up-run lane in A road is for the vehicle ' of left and right commentaries on classics.The up-run lane in B road travels for craspedodrome and left turning vehicle, and U type overhead passage way is for a left side vehicle ' in A road.The up-run lane in C road is for keeping straight on and the right-hand rotation vehicle ', and the U-shaped overhead passage way travels for the left turning vehicle in B road.The descending track in A road is for the descending use of left turning vehicle in the right-hand rotation vehicle and the B road in C road.The descending track in B road is for the descending use of through vehicles in the right-hand rotation vehicle and the C road in A road.The descending track in C road is for the descending use of left turning vehicle in the through vehicles and the A road in B road.The head end operation in A, B, C road can be directly in ground tune track tune.The pedestrian can be directly current on the ground level road at crossing.When the road surface is narrower, the U-shaped overhead passage way can be taken walkway partly, because of it is overhead part, so little to the influence of walkway, but bridge partly then should not built on the sidewalk under the Shang Qiao of viaduct reached, otherwise will influence the normal current of pedestrian greatly.
