Adaptive Spatial-Temporal Graph Construction
STAE-DGCRN introduces a novel dynamic graph mechanism that leverages temporal embeddings and spatial features to adaptively update the adjacency matrix. This approach precisely captures time-varying node dependencies in transportation networks, overcoming the limitations of static graph models in real-world traffic scenarios affected by incidents and maintenance.
Enhanced Feature Extraction with STEDGRU and Attention
The core of STAE-DGCRN lies in its Spatial-Temporal Encoder-Decoder Gated Recurrent Unit (STEDGRU) and the STAE-GCRNCell. The encoder integrates dynamic graph convolutions with GRUs to extract deep spatial-temporal features, while the decoder employs spatial-temporal attention mechanisms for robust cross-regional modeling. The STAE-GCRNCell further refines feature representation by combining lightweight graph convolutions with a Convolutional Block Attention Module (CBAM) and residual channel fusion, effectively suppressing noise and enhancing dynamic responsiveness.
Validated Superiority in Traffic Flow Forecasting
Extensive experiments conducted on four real-world traffic datasets (PEMS03, PEMS04, PEMS07, PEMS08) demonstrate that STAE-DGCRN consistently outperforms comparable baselines. This validation confirms its ability to provide higher accuracy and stability, especially for multi-step predictions and under complex traffic conditions, marking a significant advancement for Intelligent Transportation Systems.
