The invention relates to the technical field of traffic flow prediction, and provides an urban traffic flow prediction method based on a graph convolutional network and related equipment. The method comprises the following steps: dividing a target city area into unit areas according to a plurality of division scales; according to all the traffic flow data and all the unit areas under the division scale, traffic flow time characteristics of the target city area are calculated; performing feature calculation on the traffic flow time features by using a graph convolutional network to obtain final traffic flow features of the target city region under each division scale; based on all the final traffic flow characteristics, obtaining predicted traffic flow data of the target urban area under each division scale, and determining a target division scale according to all the predicted traffic flow data; and performing traffic flow prediction on the to-be-predicted urban area according to the target division scale to obtain final predicted traffic flow data of the to-be-predicted urban area. According to the method, the accuracy of traffic flow prediction can be improved.
