The invention discloses an urban road traffic state prediction method based on a macro-medium-micro hybrid simulation model, a storage medium and equipment, and the method comprises the steps: collecting historical electronic police data and traffic channelization data, inputting the historical electronic police data and traffic channelization data into a constructed macro-medium-micro integrated multi-level hybrid simulation model, and carrying out the simulation, obtaining a road traffic state in each time period and traffic flow data at each moment; constructing a traffic flow parameter prediction model based on an MVF-FA-LSTM algorithm, inputting the traffic flow data into the traffic flow parameter prediction model, and predicting the traffic flow and the passing speed of the road; and constructing a traffic state prediction model based on a fuzzy C-means clustering algorithm, inputting the predicted traffic flow and passing speed of the road into the traffic state prediction model, and predicting the traffic state of the road. According to the method, unification of microscopic, mesoscopic and macroscopic simulation models is realized, and road flow and passing speed prediction is realized, so that road traffic states are divided, and a traffic management department is guided to command and make decisions.
