Abstract

The invention relates to a method for increasing the intersection vehicle flux. On various traffic lanes before intersections, except the prior common parking lines of adjoining intersections, various traffic lanes are provided with a plurality of parking lines towards the running direction of vehicles; a reasonable distance is arranged between two adjacent two parking lines to ensure that when red lights are changed into green lights, various vehicles parked before a plurality of parking lines can simultaneously start so as to reduce the waste of green light time due to the starting of vehicles one by one after running for a distance, so the vehicle flux when the green lights flash can be improved.

Description

A kind of method that increases intersection vehicle flux

Technical field

The present invention relates to increase the method for road traffic, belong to the traffic technique field.

Background technology

In the prior art, the intersection ubiquity, and its negative effect to road traffic big be self-evident.Be without loss of generality, with car craspedodrome passing through intersection, and establish green light and red time and equate to be example, then in 50% time that red light lights, car on the highway section before intersection green light such as stop, highway section behind the intersection then is vacant, and the ability that is open to traffic of road does not add utilization fully.Only utilizing when green then in 50% time that red light lights, obtaining.Start successively after green light is bright because of each car again and acceleration needs the time, actual utilization factor is lower than 50% certainly.When along the intersection, road not only one the time, situation is poorer.As seen the existence of intersection is the major reason that road traffic blocks.An existing solution is to build crossings on different level, makes that the wagon flow on cross one another two roads is independent of each other.But, this method investment is big, and occupation of land is many, and maintenance and expense are also bigger.In addition, particularly in the city, the change of the environment that it causes, and the back wagon flow that is open to traffic is also unacceptable often to the negative effect that peripheral facilities caused.

Task of the present invention is that method, the cost with the plane is lower, land used is few, the cycle solves the problem of above-mentioned intersection shortly, and the ability that makes path link cross wagon flow increases greatly.Therefore the blockage problem of traffic, particularly urban transportation will obtain suitable big improvement.

The present invention also is to be 2007101945893 from application number, that the invention of " increase contains the method for the road traffic of intersection " by name is divided an application and the partial content won.

Summary of the invention

The following describes the method that increase of the present invention contains the vehicle flowrate of intersection road.

On each track before the crossing, except that the stop line (5) of common used next-door neighbour intersection, also the direction of coming towards car is provided with many (N bar) stop lines (5) on each track.When red light was bright, each stop line (5) was preceding, and order only stops a car, and between the car of each car that stops and its front of following, owing to the design of spacing between adjacent two stop lines (5) has a rational distance.Its size is to make that being parked in each preceding car of N bar stop line (5) can start simultaneously when red light changes green light.Thus, spacing is too small between the vehicle that stops in the present situation, each car need wait for that all each cars of its front start and walk out the waste of the green time that just can start behind the segment distance and cause one by one, reduced, thereby make vehicle flowrate when green light is bright, just the total vehicle flowrate of road is improved.For example as, use existing method, the 11st car need wait for that 10 cars of its front all start successively one by one and could the starting of the back of travelling.If establish the starting of each car and walk 2 seconds (actual) greater than this number after, the car that follows closely could start, and then counts from the moment of red light commentaries on classics green light, could start after the 11st car need be waited for 20 seconds.Use method of the present invention, can save during this period of time.If each current time of green light is 1-2 minute, then for the 11st car, the wait that said method is saved and the time of waste are its 33%-16%.

From the angle that increases vehicle flowrate and opinion, the choosing of above-mentioned stop line number N should make N car stopping only can cross traffic lights safely ensuing one during taking turns green light.

Use this method and make the length of the shared road of vehicle stop waiting red light increase, but it is no longer than each car shared link length of these vehicles when advancing that keeps a safe distance, thereby can not cause negative problem.

Method of the present invention is compared with existing method, has following advantage:

A. be the plane because of what adopt, and need not use three-dimensional method, small investment is taken up an area of and is lacked, and required construction or transformation cycle are short, and maintenance cost is low.

B. the wagon flow gait of march is accelerated, and saves time, and is fuel-efficient and help environmental protection.

C. establish the method for many stop lines on the track, make when each green light is bright the vehicle number that can pass through increase, but the change of required work and investment are little.

Description of drawings

Accompanying drawing is for realizing the synoptic diagram of the inventive method.

In the accompanying drawing,

1 traffic lights in the intersection

The preceding highway section of 2 lamps (in the intersection, the highway section that increase in the track before the traffic lights)

Highway section behind 3 lamps (in the intersection, the highway section that increase in the track behind the traffic lights)

4 former tracks

5 stop lines (many)

6 wagon flow directions

Embodiment

Provide an embodiment below.

Referring to accompanying drawing, be without loss of generality, only with the wagon flow direction shown in the arrow (6), promptly set forth for example from south to north, the rest may be inferred by analogy., (1) is traffic lights among the figure, former track (4) are totally two tracks.On each track in the one section preceding highway section of lamp (2) before arriving the intersection six stop lines (5) are set respectively, the spacing between its each stop line is to make that being parked in each preceding car of six stop lines (5) can start simultaneously when red light changes green light.When red light is bright, each stop line (5) is preceding respectively to stop a car, to green light when bright, vehicle passes the intersection together and enters highway section (3) behind the lamp, it is green light totally ten two cars (track two at most when bright, respectively have six cars preceding at six stop lines (5) of setting) start and pass through the crossing together, need wait for all that with regard to having reduced each car all each cars of its front start and walk out the waste of the green time that just can start behind the segment distance and cause one by one like this, thereby make vehicle flowrate when green light is bright, just the total vehicle flowrate in road cross place is improved.

Claims

1. method that increases intersection vehicle flux, it is characterized in that the stop line before traffic lights, the direction of coming towards car sets gradually many stop lines, distance between each stop line, make and only stop a car before each stop line, and suitably stay distance between car, make when red light changes green, vehicle behind each stop line can start safely simultaneously and advance.
