Aiming at the uneven distribution of vehicles in each traffic direction of road intersection, such as in the suburbs of the city or the intersection of main roads and non-main roads, a design scheme of intelligent control system of traffic lights with DSP embedded system as the hardware platform is proposed. The system uses CCD cameras to collect video images reflecting the road traffic scene, and then performs a series of processing on the obtained video images, and uses background subtraction to quickly obtain the vehicle information of each phase of the road intersection, and then controls the time and change of the corresponding traffic lights in real time according to the number of vehicles in each relative phase, so as to realize the adaptive control of traffic control signal lights. The test proves that the system has the characteristics of good real-time performance and flexible expansion.
