Abstract
The invention discloses a control method for smart display of traffic lights, which comprises the following steps: a, setting detection lines A and B at the stop line and in front of the stop line of an intersection, collecting the time and quantity data of the vehicle driving across a bridge measurement line; b, inputting the collected time and quantity data of the vehicle driving across based on a lane line into a central processing unit; c, carrying out releasing by the central processing unit according to a rule that a first arriver is put in first to be released; d, after the released vehicles drives cross the detection line A for C seconds, releasing vehicles later drives to the detection line B in the other directions, and analogizing in turn; and f, closing signal lights when no vehicle drives to the detection line B at all directions. The invention has the advantages of novelty conception and simple implement; and the vehicle traffic capacity of the intersection is improved effectively by collecting the processing data in real time, thereby relieving the urban traffic jam and effectively reducing the invalid waiting time for the vehicle to pass through the intersection and the invalid operation of the signal lights when no vehicle passes through the intersection so as to save power source.
Description
Technical field
The present invention relates to a kind of traffic signal control method, especially a kind of control method of traffic lights intelligent display.
Background technology
It is long that the major reason of urban traffic blocking is that vehicle passes through waiting time of grade crossing, and waiting time, long key factor was that the traffic signals of intersection can not be brought into play best current function.Make limited intersection path resource not to be fully utilized.
Existing Signal on Highway Cross nearly all is regularly to open and close.For example N direction green light is 60 seconds, amber light 3 seconds, and red light 60 seconds, other direction also is like this.So just caused following several drawbacks: 1, vehicle is by the intersection time, and other all directions all do not hinder this vehicle pass-through, and just meet red light; N direction clearance vehicle has been announced and has been finished, and the S direction is not let pass.Invalid prolongation the stand-by period of vehicle; 2, N direction traveling vehicle is many, and S direction traveling vehicle is few, causes the stand-by period unfairness by this intersection all directions vehicle, can not effectively dredge the vehicle pass-through of the many directions of wagon flow, thereby block up; When 3, no vehicle was by the intersection, traffic lights opened and closed and remain unchanged, the waste power supply.
Summary of the invention
The object of the present invention is to provide a kind of control method of traffic lights intelligent display, this method can alleviate urban traffic blocking and can effectively reduce vehicle by the invalid stand-by period of intersection, and signal lamp is ineffectually worked to save power supply when not having vehicle by the intersection.
Technical scheme of the present invention is: a kind of control method of traffic lights intelligent display, and its step: a, utilization are set up detection line A, B before being located at intersection stop line and stop line, gather time, the quantity data of the vehicle that crosses the bridge survey line; B, will collect cross the data inputs central processing unit of the T/A of vehicle by lines; C, central processing unit sail the principle of letting pass the earlier processing of letting pass into according to the pioneer; D, the C after second that is rolled away from detection line A by the clearance vehicle, the vehicle of promptly letting pass and time sailing other direction detection line B into, and the like; F, all directions detection line B all do not have vehicle and sail then signal lamp into and close.
The control device of this control method comprises detection line A, detection line B, central data processor, data cable, countdown scintillater.Detection line adopts the line of induction, sense light, camera three one.
The invention has the advantages that: novel, implement simple, by real-time acquisition process data, the bus capacity of intersection is effectively improved, thereby alleviate urban traffic blocking and can effectively reduce vehicle by the invalid stand-by period of intersection, and signal lamp is ineffectually worked to save power supply when not having vehicle by the intersection.
Embodiment
Set up bridge detection line A, B, detection vehicle to sail situation about rolling away from into by lines for preceding 50 meters at intersection stop line and stop line, import its time and quantity data into central processing unit, central processing unit data according to this comes the keying frequency and the duration of processing signals lamp.
1, do not have vehicle when each crossing and sail detection line B line into, signal lamp cuts out (save power supply, particularly night, effect was obvious).
2, sail detection line B line as vehicle into by lines, when central processing unit does not obtain other direction and is an impediment to the data that this direction vehicle passes through, the current signal of open this direction, C second behind this direction vehicle passing detection line A, (C sets the length of looking this intersection passing second, set by empirical data) after, an action on the restoring signal lamp, same direction has follow-up vehicle then to continue to let pass C second to the follow-up vehicle passing detection line A at D in second.
3, when all directions all have vehicle to sail detection line B into, then by sailing into earlier, open earlier current principle, and by the definite open current time span (homogeneous of the density of sailing vehicle into, equidirectional, direction does not hinder the quantity that the vehicle of the direction of announcement is let pass therewith, empirical data according to the traffic of each intersection is set), in case this direction vehicle (contain and do not hinder the current vehicle of this direction) let pass and finish (measuring) time-delay C second according to detection line A (C in second amber light bright, the traffic lights flicker), promptly let pass direction time time of having let pass is sailed the vehicle of detection line B direction into, by that analogy.For avoiding not rolling bridge A line for some reason away from, and set a clearance time E second that all directions are the longest because of vehicle sails detection line B line into.
For setting forth conveniently correlation word is made explanations:
Detection line A: be located at stop line, detection line B (be located at (50+n rice) before the stop line, decide according to each intersection situation, generally is no more than 50 meters, promptly establishes lines herein by the n value.
Central processing unit: single-chip microcomputer.
The invalid stand-by period: vehicle during by the intersection other all directions all do not hinder the time that this vehicle pass-through is waited for.
C second: vehicle rolls away to arrive behind the detection line A and does not hinder thereafter by the required time of clearance vehicle pass-through, general 3-5 second.In the time interval that last vehicle and back car vehicle sail detection line B in the D second same lines, D value generally is no more than 20 seconds, homogeneous let pass at interval above 10 seconds can only 3 times in.The E value according to each intersection situation decide the longest should not be above 120 seconds.
Claims (3)
1. the control method of a traffic lights intelligent display, is utilized and is set up detection line A, B before being located at intersection stop line and stop line its step: a, gathers time, the quantity data of the vehicle that crosses the bridge survey line; B, will collect cross the data inputs central processing unit of the T/A of vehicle by lines; C, central processing unit sail the principle of letting pass the earlier processing of letting pass into according to the pioneer; D, the C after second that is rolled away from detection line A by the clearance vehicle, the vehicle of promptly letting pass and time sailing other direction detection line B into, and the like; F, all directions detection line B all do not have vehicle and sail then signal lamp into and close.
