Description
Technical field
The present invention relates to a kind of control system of traffic lights, particularly relate to a kind of adaptive control system for traffic lights, belong to the technical field of Traffic signal control.
Background technology
At the parting of the ways, four sides all suspended on red, yellow, and green, three look traffic lights, and it is noiseless " traffic-police ".Traffic lights are traffic lights of international uniform.Red light is stop signal, and green light is right of way signal.Intersection, the car that several direction is come all collects in here, and what have will keep straight on, and what have will turn round, and whom allows get ahead on earth, and Here it is will accept traffic lights commander.When red, forbids keeping straight on or turning left, is not hindering under pedestrian and vehicle condition, allow vehicle to turn right; Green light, permits vehicle and keeps straight on or turn; Amber light is bright, within being parked in crossing stop line or zebra crossing, has continued to pass through; During amber light flicker, warning vehicle is taken care.
Traffic lights are divided into: motor vehicle signal lamp, bicycle signal lamp, pedestrian crosswalk signal lamp, direction pilot lamp (arrow signal lamp), lane signal lamp, flashing, alarming signal lamp, road and railway plane intersection signal lamp.And for motor vehicle, need to rely on motor vehicle signal lamp; And need to rely on pedestrian crosswalk signal lamp for pedestrian.
For pedestrian crosswalk signal lamp, itself and server connect, the traffic signals of reception server transmission, generate and have red pedestrian to stand pattern and interior have green rows people to walk one group of signal lamp that pattern groups becomes by interior, instruct walk.Facilitate pedestrian by road thus, and effectively vehicle is controlled.
Although existing traffic lights in use, more bring facility.But in fact it go back Shortcomings.As application number: in the file of 201410441582.7 applyings date: 2014-09-01, disclose that " a kind of traffic lights comprise column, cross bar, the first signal lamp group, LED.Wherein, the first signal lamp group is three look traffic lights, and LED comprises the three-color LED light group with the first signal lamp group solid colour.First signal lamp group is fixed on cross bar, and LED is vertically fixed on column front; LED and signal lamp group connect outside same signal and control source ".Make the first signal lamp group and LED can send ruddiness, gold-tinted, green optical signal simultaneously, be equivalent to increase signal lamp light-emitting area, thus make automobile driver can at more remote discernible signal lamp.
And at other one section of application number: in the file of 201410758815.6 applyings date: 2014-12-11, disclose " a kind of heat radiation traffic lights, comprise traffic signals lamp stand, electrical equipment, light source and Connection Block, be connected with Connection Block bottom described traffic signals lamp stand, top connects light source, the cavity placing electrical equipment is set in the bottom of traffic signals lamp stand, described Connection Block and ground are fixed, in described traffic signals lamp stand, water stream channel is set, the reserve tank being placed in below ground is connected with in the lower end of described traffic signals lamp stand, reserve tank is communicated with water stream channel, described Connection Block is provided with inlet opening, described inlet opening arranges plug, in the bottom of described reserve tank, osculum is set, osculum connects drainpipe, drainpipe arranges operation valve ", solve the problem of heat radiation thus.Adopt the heat radiation traffic lights of this invention technical scheme, quality is light, and convenient heat radiation.
Although above-mentioned document has carried out structure improvement to existing traffic lights, it is still Shortcomings functionally.Existing existed traffic lights can only carry out signal lamp display according to the signal of server transmission, and according to trigger pip, region picture formation image cannot be processed in time, cannot to publish picture the coverage rate of pedestrian in picture by automatic decision, make signal lamp effectively can not transmit real-time pedestrian's picture situation, can not adjust in time traffic signals, reduce control efficiency thus.
