1. An integrated intersection traffic control system, comprising:

  • a CPU;

    a flow statistic module, for receiving information regarding vehicles passing through an underground inductance coil of each lane, processing the information into traffic data of each lane and each direction, and sending the traffic data to the CPU;

    an intelligent light control module, for receiving from a panoramic camera pictures of vehicles on each lane and on each direction, processing the pictures into queuing data of the corresponding lane and direction, and sending the queuing data to the CPU;

    a vehicle speed detection module, for receiving information regarding vehicles passing through the underground inductance coil of each lane, processing the information into speed data, and sending the speed data to the CPU;

    a snapshot control module, for receiving snapshot commands from the CPU, creating snapshot control signals, and sending the snapshot control signals to snapshot cameras; and

    a light control module, for receiving lighting mode control commands from the CPU, creating light control signals in accordance with pre-stored lighting modes, and sending the light control signals to a light control circuit to switch on/off the corresponding power supply circuits, wherein the light control module receives light switching commands from the CPU whose execution will be given priority, creates and sends light control signals to the light control circuit to switch on/off the corresponding power supply circuits, and finally resumes the lighting mode after the light switching commands are executed;

    wherein the CPU receives and stores the traffic data of each lane and each direction, creates and stores analytic traffic data, and outputs the analytic traffic data in accordance with external commands, the CPU further receiving the queuing data of each lane and each direction as well as mode parameters input by a lighting mode selector, creating lighting mode control commands according to the mode parameters, and sending the lighting mode control commands to the light control module, the CPU further receiving light switching information input by a manual light switching device, creating light switching commands, and sending the light switching commands to the light control module, the CPU further receiving visibility data from a visibility sensor, retrieving a speed limit corresponding to the visibility data in a database, and storing the speed limit in a speed limit storage, the CPU further receiving the speed data from the vehicle speed detection module, comparing the speed data with the speed limit in the speed limit storage, and sending a snapshot command, if the speed data is greater than the speed limit, to the snapshot control module, the CPU further receiving snapshot images from the snapshot cameras through a video capture card, recognizing the vehicle identification number, and storing the images and corresponding number in a blacklist database.
