Zusammenfassung:The invention discloses a traffic light control method and control system. The control method includes the following steps that: the lighting-up state of a traffic light is initialized, a distance threshold value is set; the real-time positions of vehicles are acquired, and when it is detected distance between the vehicles and the traffic light are smaller than the distance threshold value, the vehicles send passage requests; the passage requests sent by the vehicles are received, and the quantities of the passage requests received in different passage directions is put into statistics; and the quantity difference of the passage requests received in the different passage directions is calculated, and the lighting-up time of the red lamps and green lamps of the traffic light in the different passage directions is adjusted according to the quantity difference. According to the traffic light control method, the passage requests sent by the vehicles in different passage directions are obtained, and the quantity d
