Abstract In order to address the air traffic complexity prediction problem, an ICA-LSTM prediction model is established by constructing the air traffic interdependent network and extracting the nonlinear spatiotemporal dynamic characteristics of air traffic data, which improves the accuracy of prediction. Firstly, based on the complex network theory, taking aircraft and control sectors as the research objects, a flight-control air traffic interdependence network was established. Secondly, network characteristic indexes were selected from the three dimensions of “point-line-surface”, and the common factors of these indexes were extracted using factor analysis method, and an air traffic complexity model was established. Finally, a spatiotemporal series of air traffic data is constructed, the independent component analysis (ICA) is used to extract data sample characteristics, and an ICA-LSTM air traffic complexity prediction model is established. ADS-B operational data from the Beijing terminal area is used for verification, and the results show that the model can effectively predict air traffic complexity. Moreover, compared with traditional LSTM and SVM models, the ICA-LSTM model has higher prediction accuracy.
