Abstract
Disclosed is a crossroad viaduct without traffic lights, which is a convenient and direct crossroad fast-track, adopts a single-layer overhead style and has advantages of small floor space, small volume of work and low cost. Pedestrians and vehicles can take respective ways, lines are clear and changing road is unnecessary. As shown in Figure 1: vehicles which are running straight reach road A and then turn right into road E to finish straight running; vehicles which are turning right reach road B and then turn right into road C to finish right turning; vehicles which are turning left reach road B and turn right into road D, and then turn right again into road E to finish left turning; vehicles which are taking U-turns can directly take U-turns under the bridge; and pedestrians can pass freely within a central area under the bridge.
Description
Technical field:
What the present invention relates to is a kind of traffic lights that need not in the use of highway crossroad, and pedestrian and vehicle can straightway crossroads viaduct.
Background technology:
At present, existing crossing viaduct exists following shortcoming:
1, four corners of the world four direction can't be accomplished harmoniously, unblocked, and what have can't turn left, and what have can't reverse end for end, and then needing on both direction of having commands with traffic lights.
2, walk inconvenience, or impassable at all.
3, difficulty of construction is big, and the occupation of land scope is wide, and project scale is big, the cost height.
4, for than the narrow lane face, can't build crossing viaduct.
5, do not consider the problem of vehicle lane change, in case vehicle needs lane change, will hinder passage rate greatly, and easily cause traffic accident.
6, passage is too complicated, behind the last viaduct of driver, violates easily and swoons, and goes to the wrong way outlet.
Summary of the invention:
The present invention is the current fast viaduct in a kind of easy, direct crossroad.What it adopted is the overhead mode of individual layer, the superiors are an interface channel that four crossings are linked together, have only left turning vehicle just can use this interface channel, interface channel respectively has a craspedodrome passage that spirals descending between each crossing, for the left turning vehicle at crossing, through vehicles and through vehicles left side shared.(as through vehicles and the shared craspedodrome passage of vehicle that need be turned left toward north by the west by Nan Wangbei, the rest may be inferred by analogy for it).Be provided with four descending tracks of directly turning right on the viaduct in addition, four up-run lanes (for the vehicle that needs craspedodrome or left and right commentaries on classics uses).
When vehicle need be kept straight on, can directly go up bridge and enter direct lane.When vehicle need be turned right, can directly go up bridge and enter right-turn lane.When vehicle need turn left, can directly go up bridge and enter interface channel, turning right then enters direct lane.When need reversing end for end, vehicle can directly under bridge, reverse end for end.Pedestrian and bicycle also can have free passage in center range under the bridge.
Comparing the present invention with other viaduct has the following advantages:
What 1, the present invention adopted is the overhead mode of individual layer, and clear in structure is simple, and line construction is convenient, can directly be erected on the four direction at crossing, and the occupation of land scope is little, and engineering quantity is little, and cost is low.
2, need not traffic lights, pedestrian, vehicle are taken their own roads, and be unblocked, and vehicle can directly reverse end for end on ground under the bridge, and the pedestrian can have free passage in center range under the bridge, and is very convenient.
3, vehicle is taken their own roads, and need not lane change, and is current fast smooth and easy.
4, the clear unanimity of driving route, the driver comes into plain view.
5,, also can build use for crossroad than the arrow path road.
Description of drawings:
Fig. 1: than the vertical view of narrow road face crossing viaduct mode.
Fig. 2: than the lateral view of narrow road face crossing viaduct mode.
Fig. 3: the vertical view of broad road surface crossing viaduct mode
Fig. 4: the lateral view of broad road surface crossing viaduct mode
The specific embodiment:
The present invention adopts individual layer viaduct mode, according to the road surface situation multiple moulding is arranged.Following examples will the invention will be further described in conjunction with the accompanying drawings.
Referring to accompanying drawing 1, accompanying drawing 2, this viaduct is the overhead mode of individual layer, can directly be erected on the four direction of road cross, takies less to the road peripheral extent.Vehicle for the needs tune need not bridge, can directly reverse end for end under bridge.The pedestrian can have free passage in center range under the bridge.For A road on the vehicle of need craspedodrome, craspedodrome is finished in the E road of turning right then.Change trains or buses to go up the B road about needing, right-hand rotation is finished in the right-hand rotation vehicle C road of directly turning right, and left-hand rotation is finished in left turning vehicle turn right the earlier E road of turning right again behind the D road (interface channel).
As accompanying drawing 1, when setting up viaduct,, can partly adjust the radian that detours in the overhead part in A, B, C road and D, E road if the road surface is narrower.In order to guarantee that vehicle has enough radians that detours on D, E road, the overhead part in A, B, C road can be expanded outward toward road, also the radian that detours in D, E road can be done circularly, also the D road can be upwarped height with the circular radian place that increases the D road and A, B, C road.
When the broad of road surface, can construct by Fig. 3, Fig. 4.
Completely for suffering from, a large amount of vehicles is trapped in the crossing and is arranging long queue each metropolis car, slatterns great amount of fuel oil, produces a large amount of waste gas, is consuming a large amount of time of people now.Can build all straightway viaduct of a kind of traffic, be an extremely urgent major issue of each city.I wish that sincerely this viaduct can save our city, save our home.
If same viaduct mode is all unified to use in the whole nation, what then the driver to which city can make easy progress from experience has crossed the crossroad.
Claims (7)
1, this crossing viaduct, it is characterized by and on the individual layer viaduct, establish an interface channel that four crossings are linked together (the D road in the accompanying drawing 1), have only left turning vehicle just can use this interface channel, interface channel respectively has a craspedodrome passage that spirals descending (the E road in the accompanying drawing 1) between each crossing, for the left turning vehicle at crossing, through vehicles and through vehicles left side shared.(as through vehicles and the shared craspedodrome passage of vehicle that need be turned left toward north by the west by Nan Wangbei, the rest may be inferred by analogy for it).Be provided with four descending tracks of directly turning right on the viaduct in addition, four up-run lanes (for the vehicle that needs craspedodrome or left and right commentaries on classics uses).
