Abstract

Fusion airspace represents the current emerging direction in airspace development. The existing traffic control management methods designed for manned aircraft are insufficient to predict the saturated flow of UAVs in fusion airspace, and thus cannot provide a reference for airspace planning. To achieve the prediction of UAV saturation flow in fusion airspace, this study proposes a UAV saturation flow prediction method based on Wavelet Reconstruction-Autoformer (WR-Autoformer) . Initially, traffic flow data is decomposed using wavelet transformation to mitigate the impact of noise and highlight data characteristics. Subsequently, the Autoformer model’s deep decomposition mechanism and autocorrelation mechanism are utilized for foundational prediction. Considering the key factors affecting saturation flow, three UAV traffic correction coefficients are introduced. Finally, the UAV saturation flow prediction for fusion airspace is outputted by combining the UAV saturation flow calculation method. Upon verification, the WR-Autoformer model has reduced the average absolute error and mean squared error by 13% to 48% in 48-hour and 96-hour forecasts, and the predicted saturation flow has increased by 36% to 38% compared to the current state. The experimental results prove that the model can achieve accurate predictions and enhance the saturation flow of UAVs in fusion airspace, while the vertical separation of UAVs meets the safety requirements for Class A aircraft.
