Abstract
The invention discloses a roundabout capable of reducing traffic intersections. According to the technical scheme, the roundabout is of a triangular shape or a quadrangular shape or a polygonal shape, the roundabout is provided with arc corner portions which are the same with the edges in number, and the arc corner portions are right opposite to the roads of a crossing respectively. Due to the fact that all vehicles in the crossing are driven in the rightward direction along the roundabout and driven in the leftward direction in the arc positions, all the vehicles can be driven orderly one after another, the defects of an existing circular roundabout can be overcome in many aspects, the chance of producing traffic intersections in the roundabout can be greatly reduced, the traffic jam and the traffic accidents can be effectively avoided or greatly reduced, and meanwhile the occupied area of the crossing can be further narrowed.
Description
Technical field
The present invention relates to road equipment, the rotary island of intersection specifically, more specifically a kind ofly reduce the rotary island that vehicle crosses.
Background technology
Now the rotary island of intersection is all circular, thus also be disk, and the diameter of this circular rotary island all is less than the distance at relative crossing, all between rotary island and crossing, reserves runway.When vehicle passes through such intersection, except what directly turn right, other vehicle has the possibility crossed.This causes traffic jam on the one hand, has also strengthened on the other hand the danger of accident.
In addition, the intersection of most circular rotary islands is all to be that road circular arc (interface portion in adjacent two tracks) is arranged to become parallel circular arc with circular rotary island by surrounding road, and such intersection floor space is very large.The more and more valuable city in soil, more and more inadaptable.
Summary of the invention
The objective of the invention is in order to overcome the defect of circular rotary island, a kind of rotary island that vehicle crosses that reduces is provided, to reduce the chance cross at rotary island place vehicle, avoid the jams and the generation of traffic accident, reduce the intersection floor space simultaneously.
Technical scheme of the present invention is: rotary island is triangular in shape, quadrangle or polygon, and the circular arc bight identical with limit quantity is set, and circular arc bight faces a road of intersection.
Convenient for Turning travel, it is round and smooth excessive that the limit of circular arc bight and rotary island is.
Rotary island of the present invention can be built into by masonry, the structure as the circular rotary island in prior art.Also can be made by metal material.Can also be made by metal material and plastic material collocation.
When rotary island adopts metal material and/or plastic material, metal material and/or plastic material need to be fixed in road surface by securing member.This is in order to make whole rotary island fix and be unlikely to be collided easily displacement by vehicle.
For driving at night or the darker situation down train convenience of light, on rotary island edge material, adhere to fluorescent material.
No matter adopt what material to make, rotary island can form in the intersection site operation; Also can manufacture in advance parts, rear to on-the-spot splicing installation.Rear a kind of mode adapts to and the rotary island of being manufactured by metal material and/or plastic material more.
, quadrangle triangular in shape as for the rotary island shape or polygon, or regular polygon, this depends on that the road quantity of intersection and road distribute.The limit of rotary island or the quantity at angle are identical with road quantity.Because the bight of rotary island faces road, so, if road uniform distributes, rotary island is equilateral triangle, square or regular polygon, otherwise each of rotary island limit is not just to equate fully.
When vehicle enters the intersection that rotary island of the present invention is set, destination party is to the vehicle for turning right from the Guai Chu intersection, track of turning right.And destination party enters and keeps straight on and the track of turning left can be rolled respectively intersection away from along roundabout ahead by oriented identification to the vehicle for keeping straight on and turning left.
This shows, all vehicles by intersection are all to do the direction running (except turning left in arc position) of right-hand bend along rotary island, thereby can accomplish orderly current in single file.This has just greatly reduced, and vehicle crosses and the probability of lane change.
The size of rotary island, and the distance of rotary island and peripheral path, be as the criterion to meet the standard that oversize vehicle travels smoothly and turn round.
In sum, rotary island of the present invention, overcome the defect of present circular rotary island from many aspects, greatly reduced the chance crossed at rotary island place vehicle, can effectively avoid or greatly reduce the generation of traffic jam and traffic accident.Can also dwindle the intersection floor space simultaneously.
The accompanying drawing explanation
Fig. 1 is a kind of form of rotary island of the present invention---square rotary island.
Fig. 2 is the another kind of form of rotary island of the present invention---regular hexagon rotary island.
The specific embodiment
Embodiment 1
The square rotary island, arrange four circular arc bights, and four arc chord angle sections face respectively four roads of crossroad.
It is round and smooth excessive that the limit of circular arc bight and rotary island is.
Be built into the structure as the circular rotary island in prior art by masonry.
Site operation is made at the parting of the ways.
Embodiment 2
The regular hexagon rotary island.Six circular arc bights are set, and six arc chord angle sections face respectively six equally distributed roads of intersection.
It is round and smooth excessive that the limit of circular arc bight and rotary island is.By metal material, made.Manufacture in advance parts, rear to on-the-spot splicing installation.
Claims (6)
1. reduce the rotary island that vehicle crosses, it is characterized in that: rotary island is triangular in shape, quadrangle or polygon, and the circular arc bight identical with limit quantity is set, and circular arc bight faces a road of intersection.
2. according to the rotary island of claim 1, it is characterized in that: the limit of its circular arc bight and rotary island is round and smooth excessive.
3. according to the rotary island of claim 1, it is characterized in that: rotary island is built into by masonry, or metal material makes, or plastic material makes, or metal material and plastic material collocation are made.
4. according to the rotary island of claim 3, it is characterized in that: when rotary island adopts metal material and/or plastic material, metal material and/or plastic material are fixed in road surface by securing member.
5. according to the rotary island of claim 1, it is characterized in that: on rotary island edge material, adhere to fluorescent material.
6. according to the rotary island of claim 1, it is characterized in that: rotary island forms in the intersection site operation; Perhaps manufacture in advance parts, rear to on-the-spot splicing installation.
