When the road traffic capacity is low, the server module 110 sends traffic information to the traffic guidance center and the communication device, and simultaneously returns traffic data to the processing center module 130, and the processing center module 130 starts the early warning module 140 to early warn the road traffic capacity, such as whistling or taking measures for controlling traffic lights.
When the road traffic capacity is poor, the server module 110 will quickly start the alarm device in the early warning module 140 through the processing center module 130, such as flashing signal lights, to elongate the whistle, and at the same time, an emergency plan is adopted to prevent the occurrence of road traffic accidents.
The invention also provides a control method of the traffic data acquisition and processing system, which comprises the following steps:
step 1, the sensing module 150 transmits the measured road meteorological information to the processing center module 130, and the traffic volume module 120 transmits the measured traffic volume data to the processing center module 130;
step 2, the database of the processing center module 130 collects and stores the received data information and transmits the data information to the server system;
step 3, the server system analyzes and judges the received data information and monitors real-time road conditions;
step 4, the server judges and processes the traffic road conditions according to the detected road traffic capacity, and calculates the road traffic capacity coefficient according to the meteorological data and the traffic volume data:
wherein s is0Is the coefficient of visibility of the image,
