The invention relates to a regional traffic signal timing method and system based on reinforcement learning, and belongs to the technical field of traffic signal timing processing. According to the method, after regional traffic environment data and vehicle track data are subjected to data extraction to obtain intersection and signal lamp composition elements, a regional traffic signal timing task is determined based on the intersection and signal lamp composition elements, then a regional traffic waiting model is constructed based on the regional traffic signal timing task, and finally, the regional traffic waiting model is constructed. A multi-agent reinforcement learning algorithm is adopted to learn and train a regional traffic waiting model, an optimized strategy-based NAC algorithm is combined to complete a coordinated optimization process of each agent strategy in a region, and an RNN recurrent neural network is introduced to process an optimization coordination result generated in the coordinated optimization process to obtain a regional traffic signal timing scheme. And therefore, the problem of dimension disaster in the existing traffic signal timing process can be solved.
