Accelerating Time-Optimal Trajectory Planning for Connected and Automated Vehicles with Graph Neural Networks

Andreas A. Malikopoulos, Viet-Anh Le

A graph neural network provides warm starts that let numerical optimizers compute time-optimal trajectories for connected automated vehicles much faster.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The trained model produces online predictions that serve as warm-starts for numerical optimization, thereby enabling rapid computation of minimal exit times and the associated feasible trajectories.

C2weakest assumption

That the graph neural network trained on offline-generated data will generalize to produce effective warm starts for previously unseen online traffic configurations without degrading the quality or feasibility of the resulting optimized trajectories.

C3one line summary

A graph isomorphism network with edge features is trained on offline data to provide warm starts for numerical optimization of time-optimal multi-agent trajectories in connected automated vehicles, reducing computation time while preserving performance through replanning.
