Data-driven social-cognitive navigation for energy-efficient and low-carbon autonomous shipping (opens in a new tab)
This study introduces a Social-Cognitive Navigation Framework (SCNF) for autonomous shipping, using historical and real-time AIS data to enhance safety and efficiency. The framework combines a Recursive Hypergraph Transformer, Level-k reasoning, and a game-theoretic planner, outperforming existing methods in 500 trials. It achieved zero collisions, improved path efficiency, and reduced traffic disturbance in crossing and overtaking scenarios. While it suggests sustainability benefits, direct fuel and emissions reductions were not measured.
