FedeRICo: Federated Region-Influenced Coupling for Traffic Flow Prediction

FedeRICo is a federated traffic forecasting framework that addresses heterogeneity across client sensor subgraphs by combining gradient-level collaboration with boundary-aware residual communication. It uses a dual-branch architecture: a globally guided branch for transferable forecasting structure and a private residual branch that preserves client-specific corrections and incorporates boundary residual signals. Experiments on four real-world traffic benchmarks show that FedeRICo outperforms state‑of‑the‑art federated spatial‑temporal baselines while keeping training runtime competitive.

Neural Architecture Search for Traffic Prediction: A Survey of Methods, Challenges, and Future Directions

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.

HLSR: Hybrid Live Forecast Selective Dynamic Vehicle Rerouting for Real-Time Congestion Avoidance

HLSR is a selective hybrid live‑forecast vehicle rerouting framework designed to reduce urban traffic congestion. It combines live edge speeds with short‑horizon forecasts, using dual‑threshold congestion detection, calibrated upstream selection, and driver‑tailored travel‑time prediction. The method introduces approaching‑vehicle expansion, travel‑time‑weighted k‑shortest‑path generation, and a horizon‑dependent hybrid live‑forecast segment speed for multi‑cost route allocation.

Traffic Engineering in Large-scale Networks with Generalizable Graph Neural Networks

The paper introduces TELGEN, a traffic engineering algorithm that uses graph neural networks to predict an optimal TE algorithm rather than a direct solution. TELGEN generalizes across diverse network topologies and traffic patterns, achieving less than a 3% optimality gap on networks up to 5,000 nodes and 3.6 million links, while reducing solving time by up to 84% and training time by up to 79.6% compared to existing methods.
