The invention discloses a traffic signal optimization method and system based on artificial intelligence, and the method comprises the steps: collecting vehicle microscopic behavior data, and obtaining a driving intention prediction result; according to the driving intention prediction result, constructing a dynamic vehicle motion track; and completing the optimization of the intersection traffic signal by using the constructed dynamic vehicle motion trail. The traffic signal response speed and accuracy can be effectively improved, the traffic jam is reduced, and the traffic efficiency is improved. By adopting the convolutional neural network and the long and short term memory network, the system can automatically extract and analyze the driving behavior characteristics and mine the driving intention information, thereby optimizing the duration and phase sequence of the signal lamp and ensuring the smoothness of the traffic flow. Besides, the dynamic planning method based on the Markov process model enables the signal optimization decision to be more scientific and reasonable, can adapt to the change of traffic flow in real time, and further improves the intelligent level of traffic management.
