Description
Technical field
The utility model relates to urban transportation facility technical field, specifically a kind of efficient fast passing crossing grade separation
Bridge.
Background technique
In general, traffic is increasingly prominent to the restriction of circulation with the development of urban economy, the public transport such as subway only have
Groups of people take, and private car trip has become a kind of very universal thing, and it is difficult that urban traffic blocking has become puzzlement various regions
To solve the problems, such as.Building viaduct at the parting of the ways is the good means that solve the above problems, but most viaducts are only capable of
Straight trip and right-hand bend can not directly carry out left steering on bridge and reverse end for end the overpass of backward going, and common grade separation
Bridge is not only high but also big, be usually present take up a large area, the number of plies is more, consumed construction material is more, cost of investment is big, long construction period,
Difficulty problem is built, thus, it reduces cost and the Blind Points in Design of Grade Separation that can quickly complete becomes a great problem.
Traffic at this stage the more is controlled the more stifled, and that takes at present controls stifled measure and can only treat the symptoms and cannot effect a permanent cure, then what is to control
Stifled sheet.The main reason for causing traffic congestion is understood, has just had found and control stifled sheet.As long as everybody arrives the cross of road
It is conscientiously observed by crossing, it finds that crossroad, which sends out a warning, hinders the traveling of vehicle, present urban transportation is exactly caused to gather around
Block up most important reason.Therefore vehicle and pedestrian can be allowed safe in the case where cancelling crossroad signal lamp
Ground, continuously by crossroad be exactly control it is stifled this.
In general, now common crossroad, the time that once giving a green light allows vehicle straight trip to pass through is about 60
Second or so, it is about 30 seconds or so that once giving a green light, which allows vehicle to turn left through the time of crossroad, because of cross
Vehicle on longitudinal and transverse two roads at crossing cannot travel simultaneously, it is necessary to pass through in turn, so the vehicle of all directions passes through ten
The period at word crossing is exactly (60+30) × 2=180 second, the vehicle on the road of crossroad every, is given a green light accumulative allow directly
The time that row passes through only accounts for (60 ÷ 180=1/3) one third of total time, and two time that its excess-three is divided on Through Lane is all
Sending out a warning, no thoroughfare for vehicles.It gives a green light and adds up to allow to turn left only to account for (the 30 of total time by the time of crossroad
÷ 180=1/6) 1/6th, add up on left turn lane total time six/fifth is that send out a warning what no thoroughfare for vehicles, this
A little data further illustrate the red light of crossroad, exactly cause the arch-criminal of traffic congestion.
When the vehicle on road is bumper-to-bumper when driving, at one in driving cycle 180 seconds, on Through Lane
Vehicle driving stops moving ahead after 60 seconds it is necessary to encounter red light, thus the efficiency that is open to traffic on Through Lane be exactly (60 ÷ 180=
0.33) 33%.Similarly, left turn lane and right-turn lane efficiency of averagely driving a vehicle are also 33%, therefore crossroad setting signal
Driving gross efficiency when lamp is 33.3%.
The reasons why setting signal lamp is because the motor vehicle on longitudinal and transverse staggered road is passing through four crossway at the parting of the ways
When mouth, cross one another traveling in the same plane, be very easy to that traffic accident occurs.So should allow it is longitudinal and transverse staggeredly horse
The vehicle wheel prevalence of road is sailed, and is on a longitudinal or lateral road, turning left also must be in turn with the vehicle of straight trip
Traveling could be safe, and the work that commander's vehicle orderly travels is exactly to be completed by signal lamp.Signal lamp brings safety to vehicle
Simultaneously, its red light also causes serious congestion to traffic to traveling.
From on present road keep straight on and left and right turning roadway number and transit time length from the point of view of, left and right turn
The vehicle of curved passage about respectively accounts for crossroad and is open to traffic 15% or so of total amount, and it is 70%. left to account for about the total amount that is open to traffic for the vehicle of straight trip
It is right.Through vehicles and left vehicle turning in order to allow in the left vehicle turning and another road that account for the total amount 15% that is open to traffic now
It safely and conveniently passes through, forces and account for 70% Through Lane of total amount that is open to traffic, sent out a warning in total time 2/3rds time and forbid vehicle
Passage, to give way to vehicle on the vehicle to turn left on this road and another road, thus causes traffic congestion.
It is well known that the efficiency that is open to traffic of crossroad all may be used if viaduct has all been built in each crossroad in city
To reach 100%, traffic congestion can be solved thoroughly.Because requirement of the country to left turn lane radius is especially big, thus makes
The occupied area of viaduct is especially big, to build viaduct at the parting of the ways, must just remove a large amount of building in crossroad.
An inch of land is an inch of gold in present city, room rate be even more it is high frightful, the building removed around crossroad builds viaduct, and cost is each
What a city was difficult to bear, so now common viaduct, can not popularize in city at all.
Utility model content
The technical assignment of the utility model is to solve the deficiencies in the prior art, provides a kind of efficient fast passing crossing grade separation
Bridge.The utility model is because the viaduct of design is without left-hand bend car lane, its occupied area is very small, in city
Each crossroad can hold this bridge without removing the building around crossroad, it can be popularized in city, institute
It is to solve the unique good plan of urban traffic blocking to say the viaduct popularized in city and do not have left-hand bend car lane.Here it is
Design the original intention of the efficient fast passing crossing overpass without left-hand bend car lane.

These need the vehicle to turn left can be by Through Lane, right-turn lane and fold-back lane, can be successfully
Driving destination is reached, only to walk some distances more.The total distance of the vehicle driving of trip has and has less, primary
Trip mileage takes 5 kilometers of mediant to calculate, and every section road in city is about 0.5 kilometer, then 5 kilometers of traveling will
By 10 section roads, it is demonstrated experimentally that the vehicle arrived at the destination that turns left is needed, as long as passing through Through Lane, right-turn lane
With fold-back lane, multirow is sailed 2 section roads and can be arrived at the destination, then calculates its efficiency that is open to traffic: 10 section road of row is just
The place that can be reached, needs to run 12 section roads and gets to, the driving efficiency in its lane is exactly (10 ÷ 12=0.83) 83%.It needs
Turn left and the vehicle turned right efficiency of averagely driving a vehicle is (83%+100%) ÷ 2=91.5%, the number of through vehicles is to turn left
Curved and more than 2 times of right-hand bend summation are calculated by 2 times, and the gross efficiency that viaduct is not provided with left turn lane is (91.5%+100%+
100%) 3=97.2% ÷.It is not provided with the viaduct to turn left, the efficiency that is open to traffic is increased to 97.2% from original 33.%, will subtract
Light traffic congestion.With " the special small loss " of 15% left vehicle turning " change its course traveling ", to exchange the big benefit of whole driving vehicles for
Benefit is worth realizing.
It is well known that vehicle, when encountering red parking on road, still in work in oil firing, crossroad takes engine
Disappear after signal lamp, vehicle can ceaselessly be run on road, reach up to destination, be not provided with so crossroad has been built
The city of the viaduct of left-hand bend, eliminates signal lamp, so that it may save 20% or so fuel oil.The utility model production is stood
Handing over bridge model is exactly to be designed according to this theory.Vehicle city forward on the right side of road, can repair at the parting of the ways
Build the viaduct for not setting left-hand bend.Similarly, vehicle city forward on the left of road, the viaduct of crossroad can not also be set
Right-turn lane, and by Through Lane, left turn lane and fold-back lane, reach the place to be gone of turning right.In fact I
The viaduct that designs, so that it may be common to the crossroad of both running mode roads that (move ahead on the right side or by left side).
The structure of bridge and current principle are as shown in " viaduct " model.
Vehicle city forward on the right side of road, does not set the explanation of the viaduct structure of left turn lane:
For example, being all to be not provided with left turn lane on crossroad made of 40 meters of road intersection in two width
Viaduct, bridge is divided into upper layer and lower layer.In each direction, three motor vehicle Through Lanes of Blind Points in Design of Grade Separation (wherein have one to be
Superelevation Through Lane), two vehicle turning right lanes, a motor vehicle fold-back lane, a non-motorized lane and a people
Trade.In order to reduce influence of the bridge to streetscape, viaduct will be built shorter as far as possible.In the lower layer of bridge, lower layer is general in longitudinal lane
It is open to traffic and ground is to flat, the height of bridge opening is 3.5 meters, can successfully bus of the headroom at 3~3.2 meters.It is longitudinal
Superelevation lane, be to be excavated downwards using ground as standard, build into half ground of 1.5 meters of depths (total height of bridge opening is made to reach 5 meters)
Lower superelevation vehicle passage.Crossrange maneuvering vehicle Through Lane is passing through fold-back lane in the upper layer of bridge, the channel of its Overheight Vehicles
When, and excavated downwards using ground as standard, build into the semi-underground superelevation of 1.5 meters of depths (total height of bridge opening is made to reach 5 meters)
Lane.The height of non-motorized lane and pavement bridge opening is all no less than 2 meters.The right-turn lane of four direction is all two-way traffic,
Through Lane height in the middle part of the height of right-hand rotation crook and bridge upper layer is to flat.Four fold-back lanes on four direction just link
Above the Through Lane on the right-turn lane on both sides.The quantity of Through Lane and right-turn lane, can be according to the width of road
Du Laiding determines that the road wider than 40 meters can suitably increase the quantity of Through Lane or right-turn lane.The horse narrower than 40 meters
Road can suitably reduce the quantity of Through Lane or right-turn lane.The quantity of Through Lane whether increases or decreases, will
Retain a superelevation lane.
Vehicle city forward on the right side of road, the viaduct of crossroad are not provided with the design of left turn lane；And
Vehicle city forward on the left of road, the viaduct of crossroad are not provided with the design of right-turn lane.
Crossroad does not set the city of left turn lane, vehicle by Through Lane, right-turn lane and fold-back lane come
Reach the place to be gone；And crossroad does not set right-turn lane city, vehicle passes through Through Lane, left turning vehicle
Road and turn back come reach turn right the place to be gone.
In the above-described embodiments, the preferred forms of the utility model are described, it is obvious that in the utility model
Inventive concept under, many variations can be still made, such as the number in various lanes can be adjusted according to having a lot of social connections, this is practical
Many variations, modifications, additions or substitutions can be also made in novel essential scope.Here, it should be noted that in the utility model
Any change made under inventive concept all will fall within the protection scope of the utility model.
