SpinFlow: A Physics-Informed Spin Field Framework for Traffic Phase Inference and Transition Detection
SpinFlow parametrizes traffic phases with a latent spin vector and competitive-equilibrium mapping, then uses physics-regularized EM to invert the field from trajectories and localize transitions via a new PED metric.
