Vehicle Platooning advantages: reduce conjection greater fuel economy hierarchical control of platoons vehicle: lat and long link: formulation, splitting, reordering network: planning, goods assignment, etc. Goal: can we dynamically form platoons that minimizes travel time while minimizing fuel cost? Traffic Coordination with MARL To coordinate UAVs, we can formulate it as a Decentralized POMDP Problem. Key insight: rollout both you and a simulation of others. Also run MPC with trurcated rollouts LLMs for Traffic Signal Control LLMs for long-tail events. Run some RL thing Make LLM refine the decision Take the action
