arXiv:2606.09539v1 Announce Type: new Abstract: Spatio-temporal graph neural networks (STGNNs) have become the dominant approach for traffic prediction, yet their computational requirements pose challenges for practical deployment in intelligent transportation systems (ITS). While recent work has proposed efficient alternatives to STGNNs, a fundamental question remains unexplored: are these architectures themselves over-parameterised? We examine this question using the Spatio-Temporal Graph Convolutional Network (STGCN), one of the most widely adopted models in this domain. Through systematic
The increasing computational demands of advanced AI models like STGNNs for real-world applications are prompting a re-evaluation of architectural efficiency to enable broader deployment.
This research directly addresses the computational and scalability challenges hindering the practical application of highly effective AI models in critical infrastructure like intelligent transportation systems.
A clearer understanding of optimal architectural depth for STGCNs will lead to more efficient and deployable traffic prediction systems, reducing computational overhead without sacrificing performance.

More efficient traffic prediction leads to reduced congestion and improved urban mobility.
The lessons learned about model over-parameterisation in STGNNs could inform design principles for other computationally intensive graph neural network applications.
