The present invention discloses an intelligent traffic light control system. The system comprises an image collection unit, a DSP image processing unit, an image storage unit, a communication unit anda signal lamp display control unit. The image collection unit comprises a camera, the camera is connected with the DSP image processing unit, and the image processing unit is connected with the communication unit and the signal lamp display control unit. The camera is taken as an image collection device to connect with an Ethernet module. The communication module and the like are taken as data transmission channels, and the image processing unit and the signal lamp control unit are employed to process for the image data to achieve intelligent control for the signal lamp so as to effectively avoid the blindness and the mechanism of the traditional signal lamp and utilize the road resource to the maximum extent.
