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.

REARL is a closed‑loop simulation enhancement framework that combines real traffic data with large language models (LLMs) to improve autonomous driving simulations. It clusters real traffic, uses cluster centers as representative scenarios for the LLM, and employs a sliding‑window detector to monitor vehicle speed and spacing discrepancies. When thresholds are exceeded, the LLM adjusts vehicle decision‑making or selects matching real vehicle actions, resulting in lower Hellinger distance and MAPE compared to baselines in a HighD highway setting.

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.
