The invention provides a traffic flow prediction model determination method, equipment and device and a readable storage medium, and belongs to the technical field of Internet of Vehicles. The method comprises the following steps: acquiring historical traffic flow data of a plurality of target road sections; processing the historical traffic flow data through a random forest algorithm to obtain target data; and taking the target data as input, and training a long-short-term memory network model based on the attention mechanism to obtain a target model. According to the scheme of the invention, historical traffic flow data can be processed through the random forest algorithm, and data having small influence on a prediction result is eliminated, so that the calculation pressure of the model is reduced; according to the method, the time sequence features in the target data are extracted through the long-short-term memory network model, and the correlation of different features in the target data is considered by using an attention mechanism, so that the limitation of the influence of the sequence length is eliminated, and the prediction efficiency and the prediction accuracy can be ensured while the traffic flow parameters are predicted by using various factors.
