The invention provides a real-time optimization signal control method and system based on video traffic state monitoring. According to the method and the system, the problems of high detecting coil damage rate, inflexible setting and poor data reliability of traditional intersection actuated signal control can be solved. The method comprises steps as follows: a camera is erected above an entrance driveway of an intersection and used for collecting real-time video images of an entrance section of each guide driveway of the entrance driveway; a video detecting and processing unit is used for setting virtual detecting coils on the real-time video images and detecting the traffic state in the entrance driveway through the virtual detecting coils; a logical analysis unit is used for logically analyzing the traffic state in the entrance driveway, and a control adjustment signal is generated according to a logical analysis result and is transmitted to a traffic signal instrument; the traffic signal instrument is used for controlling or adjusting a timing plan of the entrance driveway according to the control adjustment signal.
