Device and traffic lights are electrically connected with power supply mechanism respectively is powered by power supply mechanism, the ventilating signal lamp, wireless network module and
Traffic congestion monitor is electrically connected with microprocessor respectively to be controlled by microprocessor by preset strategy, and the traffic congestion monitor is a prison
The traffic density capture device of the traffic congestion situation of intersecting roads mouth is surveyed, the microprocessor further includes for judging the situation that blocks up
Determination strategy unit, the wireless network module and central node controller communicating data and control signal, the central node
The traffic congestion signal that controller is transmitted according to wireless network module controls the signal lamp at each crossing, in the central node controller
The strategy for controlling each belisha beacon is arranged to when the traffic congestion signal for receiving wherein any one signal light path sending
When, control is in the same direction and the signal lamp of vertical direction is red light.Feasible, microprocessor can use CC2430 single-chip microcontroller.Wirelessly
Network module includes receiver and transmitter, carries out mutual signalling sum number with being arranged between the central node controller of certain
According to, it certainly further include the communication apparatus such as the network signal transceiver, such as GPRS, 3G, 4G and 5G being connect with secure network, and it is upper
The network server communicating data of position is simultaneously changed control strategy by control.
Feasible, power supply mechanism can be can also be using line powering and solar energy and wind energy using line powering mechanism
The power supply mode of equal combinations.
Feasible, in this embodiment, the traffic congestion monitor is supersonic vehicle density detector.In this hair
In other bright specific embodiments, the traffic congestion monitor is Image Acquisition traffic density detector.It is also possible to ground sense
Answer formula traffic density detector.It is feasible, it detects persistently to detect, detection information includes traffic density and shifting in investigative range
Dynamic state can be by the ultrasonic listening that is arranged on signal lamp arm when for example, by using supersonic vehicle density detector
Device detects the vehicle that opposite traveling is come, and detects its quantity and detects whether return ultrasonic wave changes greatly, is when detecting vehicle
The signal for judging congestion is then generated when close to movement and changing smaller or unchanged by microprocessor, congestion signal is sent
To central node controller, central node controller then replaces control signal lamp strategy at this time, changes control strategy and is denoted as congestion plan
Slightly, by wireless signal transmission to the crossing other microprocessors control all directions flash the redlight, until detection less than
The ultrasonic signal of metal vehicle range, this is because the signal of the ultrasonic signal strength of metallic reflection and distant place ground return
