The invention discloses a short-time traffic flow prediction method and device, electronic equipment and a storage medium, and belongs to the technical field of intelligent traffic, and the method comprises the steps: decomposing an original traffic flow sequence of any expressway target road section within a preset duration through VMD, and obtaining a plurality of IMFs with different frequencies; performing stability analysis on each IMF, and determining a time sequence category corresponding to each IMF based on an analysis result; predicting each first IMF belonging to the linear time sequence by using a pre-trained first prediction model to obtain a first prediction value corresponding to each first IMF; predicting each second IMF belonging to the nonlinear time sequence by adopting a pre-trained second prediction model to obtain a second prediction value corresponding to each second IMF; and based on each first prediction value and each second prediction value, determining a prediction result of the traffic flow of the target road section of the expressway in the next preset duration. And the accuracy of highway short-time traffic flow prediction is improved.
