Researchers have developed the Master-Agent Proto-plan System (MAPS), a novel hierarchical deep reinforcement learning architecture designed to improve coordination among autonomous vehicles at unsignalized intersections. MAPS utilizes a centralized Master agent to generate a compact "proto-plan" embedding, which is then integrated by decentralized Worker agents with local observations for vehicle control. This approach effectively decouples strategic intent from tactical execution, allowing for independent module optimization. Evaluations in the HighwayEnv simulation demonstrated that MAPS achieves collision-free navigation and significantly reduces travel time, outperforming existing methods and showing robust generalization capabilities to scenarios with more agents than initially trained.
