The invention provides a vehicle trajectory prediction method based on a spatial motion relation and a long-short time memory network, and the method comprises the following steps: collecting and preprocessing real-time data of a vehicle, extracting absolute features and relative features of the vehicle as input features, and constructing a spatial interaction diagram based on the relative features of the vehicle; constructing an LSTM (Long Short Term Memory) prediction model, and training the LSTM prediction model by taking the space interaction diagram and the absolute characteristics of the vehicle as input; and outputting a vehicle track prediction result at a future moment through the trained LSTM prediction model. According to the method, the advantages of the space motion relation and the LSTM network are combined, accurate prediction of the vehicle track is achieved, and field test results show that the method has high prediction accuracy and can provide powerful technical support for development of an intelligent traffic system.
