Abstract
The utility model relates to road reform, which mainly relates to a reform apparatus for a cross intersection. As the busy of communication, a traffic jam phenomenon is a traffic difficulty problem, particularly, jaw openings at the cross intersection, or a middle isolation zone in an arterial road always have the traffic jams. The methods to solve the diversion of the cross intersection at present have annular islands, traffic lights and overpasses (tunnels). The methods have less effect as the increase of vehicle flowrate, or the methods take more building fund and land occupation. The utility model designs a vehicle through-flow cross intersection, which makes use of a turning around passage and line changing distance to reach that all vehicles go out the arterial road from a branch road to turn right only, the vehicles drive out of the branch road to an opposite branch road or turn left, and the vehicles drive out to the opposite main carriageway along the vehicle flow direction. Since traffic lights are cancelled, all the vehicles not need to stay at the cross intersection, causing the vehicle to save fuel oil and to save running time. Vehicle engines need no idle speed and starting process, the exhaust waste gas is reduced, and thereby, the atmospheric environment quality is improved.
Description
Technical field
The utility model relates to road reformation, mainly is the transformation facility of intersection.
Background technology
Along with the automobile of setting out on a journey is increasing, solve a difficult problem that the traffic congestion phenomenon has become traffic, especially with the intersection (intersection) of major trunk roads, or the opening part of major trunk roads intermediate isolating band, often become the focus of traffic congestion.The current method of river diversion that solves the intersection mainly contains 3 kinds: i.e. A, roundabout; B, traffic lights; C, overpass bridge (or tunnel), except that overpass bridge, other 2 kinds of methods, effect may be deceived along with the increase of vehicle flowrate, and the construction of overpass bridge needs extensive fund and it is more to take up an area of, and can not build too densely, construction duration is also longer.
Sometimes, simple thing is easy being left in the basket more just, here propose two notions: first is that " thread-changing distance " is promptly under certain vehicle flowrate, vehicle is changed to the distance of the most left (or right) the required walking in track from the rightest (or left side) track, this distance is to calculate according to the vehicle flowrate of road, adds that then the development factor of wagon flow is just passable.And present road has all been ignored such design, we often see, the traffic congestion of intersection, the vertical thread-changing of vehicle (two cars are vertically striven phenomenon) causes often, at this moment " the thread-changing distance " of vehicle is almost nil, we also often see the traffic congestion of roundabout, are due to " thread-changing distance " lacks very much.In fact, the roundabout water conservancy diversion is set, and its original intention all is to allow vehicle that " thread-changing distance " of certain-length arranged, unfortunately, even annular half through very big (as the roundabout of some road of Dongguan City, Guangdong Province, directly through 50m is arranged), from calculating and actual measurement, the thread-changing distance is all less (directly through 50m, thread-changing is apart from not enough 20m), deal with so big vehicle flowrate (we remember that also former vehicle flowrate is less, and such roundabout still is very useful) at present inadequately.
Second notion is " passage that turns around of band guardrail ", and well-known, it is breakneck that vehicle turns around on major trunk roads, so the many intersections of major trunk roads or the opening of isolation strip are all put on warning sign " no turns "! On the other hand, the track that the isolation strip is arranged in the middle of some, the place that far all neither ones Gong turn around, to conveniently travelling and to dredge wagon flow all unfavorable, why not does which consider to be provided with the passage that turns around that (some) specialize in vehicle? the GuangZhou Road of current Guangzhou, be provided with the position of the passage that turns around, but passage does not protect and blocks, therefore will establish traffic lights comes staff vehicles to keep straight on and turn around, certainly, this passage that turns around of buying car in installments also is different from the passage that the designed vehicle of the utility model turns around.
The design of the intersection that the vehicle that the utility model proposes is through-flow, because the guardrail shape in the middle of the road resembles " Z " letter, with the isolation in the middle of the track, become " Z-" shape and gain the name, i.e. " Z-" (abbreviating " Z " as) type water conservancy diversion crossing, effect that can more above-mentioned preceding two kinds of water conservancy diversion is excellent, and it is low than the expense of overpass bridge, and construction is very easy to, and existing relatively method of river diversion, and following characteristics are arranged:
1, " Z-" water conservancy diversion crossing is to follow existing traffic rule, and promptly vehicle is turned right and passed in and out the track, and the personage that drives can conveniently travel as long as abide by existing traffic rules and direction board.
2, because all vehicles of saying major trunk roads are all blocked by the intermediate isolating band, can only turn right, ahead running flows to and enters A-road, therefore, has avoided the rash vehicle gone out from by-path effectively, collides with the vehicle that gallops at all speed on the arterial highway and causes traffic accident.
3, leave from by-path and think the opposite by-path or the vehicle of left-hand bend, as long as turn right earlier, enter the major trunk roads that ahead running flows to, thread-changing is to left-lane then, and the passage that turns around on the special in front band protection hurdle that is provided with turns around, and ahead running flows to rolls the offside A-road away from, thread-changing is then turned right and is sailed the opposite by-path into; The vehicle that needs craspedodrome on the A-road or turn right directly travels or changes right by-path over to, and the vehicle on the major trunk roads should be unblocked.
4, owing to cancel traffic lights, all vehicles all need not to stop in the intersection, and this will make the traffic on the road be greatly improved, and also make vehicle save fuel oil and running time.
5, because noting be used in the intersection, vehicle stops, and automobile engine is without idling and starting-up process, and the waste gas of discharge greatly reduces, thereby has improved atmospheric environment quality.
The utility model content:
The purpose of this utility model provides the through-flow intersection of a kind of vehicle, solves the water conservancy diversion problem and the traffic congestion difficult problem of intersection, the especially intersection (intersection) of solution and major trunk roads, or the focus of the traffic congestion of the opening part of major trunk roads intermediate isolating band.The intersection that the vehicle that the utility model provides is through-flow, the technical scheme that adopts is: this intersection comprises major trunk roads, by-path, major trunk roads intermediate isolating band, with the overline bridge pedestrian tunnel, characteristics are that traffic lights are not established at the crossing, and the place ahead that goes out the ahead running flow path direction on the by-path right side is provided with band " Z " passage that turns around of guardrail, be exported to the stretch that turns around between the passage from the by-path right side and be provided with the thread-changing distance, advance notice position, crossing is provided with sign board, direction board and arrival and departure timetable.
Now in conjunction with the accompanying drawings utility model is described:
The intersection that vehicle described in the utility model shown in Figure 1 is through-flow is by " band " Z " passage that turns around of type guardrail " (G) with " the thread-changing distance " (S) constitutes, in the middle of the major trunk roads of intersection, be provided with isolation strip (P) sealing, the place ahead at the right outlet ahead running of by-path flow path direction is provided with a band " Z " passage that turns around (G) of type guardrail (ABCD), being exported to the stretch that turns around between the passage from the by-path right side is thread-changing distance (S), band " Z " the type guardrail turn around passage and thread-changing apart from just having constituted the through-flow intersection of this vehicle, because the passage that turns around of band guardrail is two-way setting, middle guardrail (ABCD) shape resembles " Z " letter, with the isolation in the middle of the track, become " Z-" shape and must be called Z type water conservancy diversion crossing.
On above-mentioned intersection, come out to move towards the vehicle (being included in the vehicle that will turn left on the major trunk roads) of opposite by-path or left-hand bend from by-path, can be from right alignment left side thread-changing in thread-changing distance (S), owing to be to travel in the same way, the speed of a motor vehicle of adjacent vehicle inconsistent (thread-changing car can allow adjacent lines straightgoing vehicle) thread-changing is a thing easily, can finish general 1～2 second, changes to right line, sails the passage that turns around (G) into.Originally the channel outlet that turns around is provided with guardrail (ABCD), can not collide with the car of adjacent lane, go out major trunk roads from the passage that turns around after, vehicle can continue to cross thread-changing distance (S), keeps right and sails by-path or craspedodrome into.
The passage that turns around (G) of band guardrail has been designed in the intersection that vehicle described in the utility model is through-flow, because the outlet of passage installing guardrail (ABCD), the vehicle that turns around can sail the passage that turns around (G) at any time into, and then roll the left-lane of offside major trunk roads away from, both made things convenient for the vehicle that turns around, also traffic lights need be set, through vehicles need not be parked in the there wrongly, allows vehicle turn around.
In sum, the intersection that vehicle described in the utility model is through-flow, allow the isolation strip in the middle of the major trunk roads seal continuously exactly, the passage that turns around (G) of band guardrail (ABCD) is set in position, the vehicle that rolls away from from by-path can only be turned right and be entered major trunk roads, want to pass through major trunk roads or left turning vehicle, can only be earlier thread-changing in thread-changing distance (S), in the passage that turns around, turn around then, go out thread-changing behind the major trunk roads, by-path is sailed in right-hand rotation into, or keeps straight on and sail.
The intersection design that vehicle described in the utility model is through-flow:
In order to design convenient and practical diversion plan, at first must understand the traffic state in this highway section, comprise present and situation Future Development.The vehicle flowrate situation can be passed through actual measurement, or understands to traffic relevant department.

The specific embodiment:
1, the design of the passage that turns around (with two-way 6 tracks, middle 6m isolation strip is an example)
(1) structure of passage such as Fig. 2 have enough turning radius for making the vehicle that enters the passage that turns around, and the flat to the right Dou of left-lane moves, and makes the broadening of intermediate isolating band, and the Dou angle is about 12～15 °, and guardrail ABCD is connected as a single entity, as the two-way lane special use of turning around separately.Guardrail BC section both sides road kerb is built by laying bricks or stones, and the centre exceeds road surface 0.5-0.8m, and grass greenization planted on the surface, and AB and CD section are chosen the other galvanized steel guardrail board structure commonly used of speedway, and coat reflecting sign.
(2) turning radius of passage should be considered from the left turn traffic amount and the vehicle in this highway section, if the flow of left-hand rotation long vehicle less (unidirectional) less than 10/hour, and through vehicles flow little (unidirectional less than 500/hour), the radius of passage selects less numerical value, because long vehicle can be in the centre or right lane turn around, can save land used like this; But what consider here is that vehicle flowrate reaches the Future Development situation more greatly, should make things convenient for long vehicle to turn so choose channel radius, but the regulation vehicle just can turn around like this at left-lane, can guarantee that more driving is freely suitable.
(3) for making vehicle turn around to widen 2～3m track on one section major trunk roads both sides of the channel centerline front and back 30m that turns around in enough spaces, use the oblique line transition then.
(4) following factor should be considered in the position that passage chooses of turning around:
1. apart from the by-path outlet enough thread-changing distances should be arranged.
2. allow intensive left turning vehicle turn around as early as possible.
3. there is enough wide place that the passage that turns around is set.
4. do not have the vehicle outlet near,, should give sealing, produce the road in addition by exit rule if having.
5. turn around the quantity of passage by the decision of this highway section left turning vehicle flow fork-like farm tool used in ancient China, generally respectively establish 1 on the both sides of by-path outlet, turn around the if desired flow of vehicle is bigger, can in position increase setting, generally do not have the passage that turns around of by-path outlet to be no less than 500m apart, specifically can determine according to above-mentioned principle and highway section wagon flow situation.
2, the thread-changing distance: be exported to the distance that turns around between the passage from by-path and be " thread-changing distance ", this section way is to allow the vehicle that just rolls away from from by-path turn around to prepare, enough length should be arranged, generally choose between 100～200m, vehicle flowrate greatly then selects long, studies the vehicle flowrate verification below.
If the thread-changing distance is 100m, average speed is 45km/h, then
Conversion time T=100m ÷ (45,000m/h ÷ 3600s/h)
＝8s
Above-mentioned adjacent lane thread-changing, 2s can finish, 8s should be enough from the right lane thread-changing to left-lane.Be located in the 100m thread-changing distance, average track, peak period has 2 cars to travel, then
N=2/track of major trunk roads vehicle flowrate * 3 tracks * 45,000m/h ÷ 100m
=2700/hour (unidirectional)
This has been a very big vehicle flowrate.
We can experience at existing highway (comprising speedway), and when seeing the outlet direction board in roadside, how many required operating ranges of thread-changing is on the track.
3, sign, direction board and arrival and departure timetable:
Usually, a new operating mode can make us uncomfortable, and should there be clear and definite indication and advance notice in " Z-" water conservancy diversion crossing.The sign of a special use has been designed in the through-flow intersection of vehicle described in the utility model, be installed in the advance notice position of road, the personage that drives sees and just at once recognizes use " Z-" type water conservancy diversion method is travelled, in addition, also must do some propaganda and guide, allow the driver understand in advance and use this method of river diversion.
Fig. 3 shows the through-flow intersection of vehicle described in the utility model water conservancy diversion sign, and direction board that should be provided with and arrival and departure timetable, comprises Fig. 3-1 Z type water conservancy diversion crossing sign; The label size: height * wide=1000 * 480mm, color at the bottom of the board: white, the blue look of lines is installed in to prop up and says 30m before the arterial highway, and major trunk roads enter the preceding 100m of by-path; Fig. 3-2 gap marker that turns around is installed in 50m before the passage that turns around; Fig. 3-3 overline bridge sign; Fig. 3-4 pedestrian tunnel sign; And Fig. 3-5 thread-changing sign.
4, pavement
Vehicle described in the utility model is through-flow, and the intersection great advantage is: the vehicle that all travel on the A-road all need not to stop treating in the intersection, we can imagine the sight of the vehicle A car sped on road surface, it is very dangerous that the pedestrian is crossed road, special-purpose pavement also influences vehicle smooth, so should be set.
Fig. 4 and shown in Figure 5, pavement should adopt viaduct or subterranean tunnel, is arranged on by-path and the more place of major trunk roads infall pedestrian, and overline bridge has to be built easily, and construction is very fast, and benefit such as reduce investment outlay is suitable for the transformation of existing busy road.And pedestrian tunnel has following benefit, is suitable for building in conjunction with planning.
(1) height that falls on the pedestrian, the tunnel is more laborsaving than overline bridge little (in the tunnel at the bottom of the clear height 2.2m overline bridge clear height greater than 4.5m) pedestrian.
(2) be not afraid of in the tunnel and expose to the sun and rain.
(3) tunnel is hidden, does not hinder view, takes up an area of (road) and also lacks than overline bridge.
Specifically be provided with referring to Fig. 4, can adopt overline bridge or tunnel according to the situation of each road.
The enforcement of the through-flow intersection of vehicle described in the utility model " Z-" diversion plan, can allow the vehicle that travels on the A-road that the passage that turns around of enough thread-changing space-time and safety is arranged, thereby cancelled the traffic lights of intersection, made all vehicles need not stop to treat, unblocked.Traffic is greatly improved, and vehicle ' also fuel-economizing saves time, and the intersection does not have vehicle idling waste discharge gas, has reduced environment pollution yet.
The through-flow intersection of vehicle described in the utility model, promptly " Z-" type water conservancy diversion crossing can comparatively simply be transformed at existing road, by above-mentioned design principles, investment is few, and the duration of construction is not long yet, as long as it is arrangement is proper, little to existing traffic impact.
The through-flow intersection of vehicle described in the utility model, be in the situation of existing traffic jam, on the spot in person and make one improve imagination, also need through practical proof, suggestion selects a highway section to test earlier, investment and time that estimation can not cost a lot of money, can not cause a lot of troubles to traffic yet.By the checking of example, further improve relevant data, the more perfect scheme that provides of promoting the use of is provided.
