The paper introduces a Multi-View Coupled Tensor Decomposition (MVCTD) model for online traffic prediction that handles imperfect multi-view data such as speed, flow, and occupancy. MVCTD builds a structured latent forecasting space by jointly modeling shared spatial structures across views and view‑specific temporal dynamics, and incorporates group sparse regularization to mitigate the impact of traffic anomalies. For streaming deployment, the method performs iterative refinement only on the current latent tensor, updating other variables with lightweight closed‑form steps based on summarized historical data, which reduces runtime while maintaining accuracy even under severe missingness.

The Traffic Assignment Problem is a fundamental but computationally expensive component of transportation planning. While Graph Neural Networks have emerged as fast, data-driven surrogates, their practical deployment is severely constrained by a spatial generalization gap.
Traffic prediction is a core task in intelligent transportation systems, supporting applications such as adaptive signal control, route guidance, and ride-hailing dispatch. Deep learning models, including graph convolutional networks, recurrent networks, and Transformers, achieve strong results on standard benchmarks, but their architectures are designed by hand, requiring significant expert effort and producing models that often generalize poorly across cities and datasets.
STHMoE is a Spatio‑Temporal Hypergraph‑Enhanced Mixture of Experts framework designed for urban traffic forecasting. It separates traffic dynamics into frequency‑, time‑, spatial‑, and higher‑order representations, each handled by a prompt‑guided expert built on a partially frozen large language model. The higher‑order expert uses an adaptive hypergraph module to learn evolving spatial structures, while an entropy‑aware router balances expert usage and fuses outputs, achieving competitive results on ten real‑world traffic benchmarks.
