Description
Technical field
The utility model belongs to traffic control field, relates in particular to a kind of intelligent traffic lamp system based on microwave sounding.
Background technology
Crossroads traffic light appears at London the earliest, 1858 in London main street corner installed using burning coal gas as light sourceThe mechanical wrench formula signal lamp of red, blue dichromatism. 1868, Britain mechanical engineer Na Yite was in the view in Westminster district, LondonOn can Qian square, mansion, coal gas traffic lights be the earliest installed in the world, it is made up of red green two rotation square glass hand lamps,Wherein red expression " stopping ", green expression " passing through ". 1914, the traffic lights of electrically activating appeared at the Cleveland of the U.S.City, this traffic lights are made up of the light projector of red greenish-yellow three look circles, and this traffic lights were arranged on again New York and Chicago afterwardsIn city. 1918, traffic lights and infrared ray traffic lights that band is controlled are there are again. The traffic lights that band is controlled, one is handlePressure detector is positioned on underground, and vehicle becomes green light once approaching red light; Another kind is to start traffic lights with loudspeaker, driverWhile meeting red light, click loud-speaker, just make red light become green light. Infrared ray traffic lights in the time that pedestrian sets foot on pressure-sensitive road surface,It just can be perceived someone and will go across the road. Infrared beam can extend a period of time the red light of signal lamp, and postpone automobile and let pass, withExempt to occur traffic accident. The appearance of signal lamp, makes traffic be able to effective control, for the flow that relieves traffic congestion, raising roadAbility, reducing traffic accident has positive effect.
Signalization lamp can effectively be dredged traffic at the parting of the ways, and has for the safety of traffic participant provides by forceThe guarantee of power. But along with Chinese society, economic fast development, private car recoverable amount is blowout shape and rises, particularly forLarge-and-medium size cities, traditional traffic light control system can not adapt to day by day busy traffic now. How to improve trafficLamp control system, makes it adapt to Modern Traffic situation, becomes the urgent problem that is worth research.
The usual method of traditional crossroad access control lamp is: pass through in advance the investigation of vehicle flow, use statistical sideMethod pre-sets the time delay of both direction traffic lights, that is to say that be fixing traffic lights switching time of this traffic light system, cannot switch according to the actual vehicle flowrate at crossing. This is the most of city crossroad traffic lights of current ChinaControl method. But in fact the variation of vehicle flowrate is complicated, random with uncertain often, same crossing is notMay produce very large difference with track in the different periods. Even through long-term operation, more applicable scheme, still can send outRaw such phenomenon: what vehicle is green light direction almost there is no, and red light direction is being arranged queue and is waited and pass through, and often causes, there is the phenomenons such as empty in the waste of road operational use time, has not only affected the unimpeded of road, and wasted the energy, pollutes ringBorder. Therefore, traditional method can not adapt to the transport need of fast development, in the urgent need to there being the one can be real-time according to flowChange the traffic light systems of carrying out Self Adaptive Control.
The current design of discloseder intelligent signal lamps, is confined to according to the method for video information and image processing moreJudge the vehicle flowrate of crossing all directions, in the situation that light is bad, be difficult to identify; Though adopt the method for ground buried coilSo simple and practical, if but bury coil underground at each crossing, not only huge the but also follow-up maintenance of construction volume bothers very much; AdoptEasily be interfered by infrared detection technique, these methods have larger limitation. And existing traffic signal lamp system knotStructure complexity, in the time that the main electricity of traffic lights breaks down, traffic lights cannot be worked, and cause traffic order disorder.
