The invention discloses an intelligent traffic light control system and control method. The intelligent traffic light control system comprises a first traffic light which is arranged at a pedestrian crossing on the road, and a second traffic light, a plurality of waiting zones are symmetrically arranged at the two ends of the pedestrian crossing, multiple waiting lots are arranged at every waitingzone, and one power generator is laid in each waiting lot; the control system further comprises a controller, a piezoelectric sensor, a tachometer and a storage battery, the tachometer is installed on the first traffic light, and the tachometer, the piezoelectric sensor, the first traffic light and the second traffic light are all connected with the controller; the power generators device are connected with the storage battery which is used for supplying power to the control system. According to the intelligent traffic light control system and control method, the influence of the environmenton a recognition result of an intelligent traffic light recognition system can be reduced, the light change duration is further delicately controlled, the passage efficiency of pedestrians and vehicles is increased, hence, energy is conserved and emission is reduced.
