The invention relates to a traffic flow prediction model training method and device, computer equipment and a computer readable storage medium. The method comprises the following steps: acquiring sample traffic flow data and traffic state influence data of a sample traffic road section at different moments in a sample time period, and obtaining traffic flow sequence information according to the sample traffic flow data and the traffic state influence data; inputting the traffic flow sequence information into a to-be-trained traffic flow prediction model to obtain corresponding time characteristics and spatial characteristics of the traffic flow sequence information in the sample time period, and obtaining spatial-temporal characteristics according to the time characteristics and the spatial characteristics; obtaining predicted traffic flow data of the sample traffic road section at the prediction moment according to the spatial-temporal characteristics; and according to the difference between the predicted traffic flow data and the actual traffic flow data, training a traffic flow prediction model to obtain a trained traffic flow prediction model. By adopting the method, the prediction precision of the traffic flow can be improved.
