The invention relates to an expressway truck flow prediction algorithm, software and device based on a deep reinforcement learning model, and relates to the field of expressway management. The algorithm comprises the following steps: acquiring first data of first vehicle flow of all lanes of a first road section at a t moment; preprocessing the first data to obtain normalized historical data; based on the LSTM model, constructing at least two single deep learning models; dividing normalized historical data into a training set and a test set according to a preset proportion, training the plurality of single deep learning models by using the training set, and determining a prediction error by using the test set; giving different weights to the plurality of single deep learning models based on the prediction error, and constructing a combined deep learning model; and based on the combined deep learning model, outputting the first vehicle flow at the next moment by inputting the first vehicle flow at the historical moment and the current moment. The model is established based on the truck flow data so as to predict the future flow and guarantee the safety of the expressway.
