Traffic lights are that non-descendants American Jia Laitemogen invented in nineteen twenty-three.Before this, railway traffic has used the automatic wigwag changed for some time.But because train runs with single column fashion by fixing timetable, and train will stop and is not easy to, and the signal therefore railway used only has a kind of order: pass through.The traffic lights of highway communication are then different, and its responsibility is to tell that automobilist stops vehicle to a great extent.
Traffic lights are made up of red light, green light, amber light.Red light represents that no through traffic, and green light represents permits passing through, and amber light represents to be gone slowly or warn.
In the last few years, along with economy and society's fast development, a lot of urban area of China started to expand gradually, and road construction is on the increase, and in-trips vehicles constantly increases, and urban transportation has entered a fast-developing stage.But the traffic of a lot of city propers but starts the Urban Traffic Jam Based occurring generally running in a lot of urban development process of China.
People find out a lot of way to improve traffic conditions, wherein just have a lot of turn-on interval adopting adjustment traffic lights.
Patent " automatically the traffic lights of adjustment turn-on interval " (application number: the traffic lights 201110144473.5) disclosing a kind of automatic adjustment turn-on interval, comprise signal lamp, wherein, also comprise control device and vehicle traffic flow analysis device, described control device is connected with described signal lamp, and described vehicle traffic flow analysis device is connected with described control device.Its objective is and automatically adjust turn-on interval according to condition of road surface, alleviate congestion in road.
Wherein said vehicle traffic flow analysis device can be image processing apparatus, described image processing apparatus comprises image collecting device and image analysis apparatus, described image collecting device is connected with described image analysis apparatus, and described image analysis apparatus is connected with described control device.
Described vehicle traffic flow analysis device can also be infrared counting device, described infrared facility comprises infrared transmitting device, infrared receiver and counting assembly, described infrared transmitting device and infrared receiver are connected with described counting assembly respectively, and described counting assembly is connected with described control device.
This mode on the one hand, needing the extra parts installed more, on the other hand, not providing concrete adjustment mode when blocking up.
Invention " during control traffic lights " (application number: 201210041135.3) disclose a kind of traffic lights, during this control, traffic lights comprise signal lamp body, timer, timer is equipped with at signal lamp body top, below timer, resistor is housed, on the right side of timer, display screen is housed, electronic eyes is equipped with at timer top, and electron plate is equipped with in the connection of signal lamp body terminal, on the left of electron plate, gauge tap is housed.Object is by electronic eye monitoring surface conditions, more manually the regulation and control traffic lights change lamp time dredges vehicle, greatly alleviates serious traffic pressure, has saved the time of people.
This mode cannot depart from manual control, cannot reach automatic adjustment, when adopting automatic regulation strategy, wastes human resources greatly.
Summary of the invention
