SFADNet: Spatio-temporal Fused Graph based on Attention Decoupling Network for Traffic Prediction
This addresses dynamic spatio-temporal modeling for traffic prediction in intelligent transportation systems, representing an incremental improvement over existing methods.
The paper tackles traffic flow prediction by proposing SFADNet, which categorizes traffic flow into multiple patterns and constructs adaptive spatio-temporal fusion graphs using cross-attention mechanisms, achieving state-of-the-art performance across four large-scale datasets.
In recent years, traffic flow prediction has played a crucial role in the management of intelligent transportation systems. However, traditional prediction methods are often limited by static spatial modeling, making it difficult to accurately capture the dynamic and complex relationships between time and space, thereby affecting prediction accuracy. This paper proposes an innovative traffic flow prediction network, SFADNet, which categorizes traffic flow into multiple traffic patterns based on temporal and spatial feature matrices. For each pattern, we construct an independent adaptive spatio-temporal fusion graph based on a cross-attention mechanism, employing residual graph convolution modules and time series modules to better capture dynamic spatio-temporal relationships under different fine-grained traffic patterns. Extensive experimental results demonstrate that SFADNet outperforms current state-of-the-art baselines across four large-scale datasets.
