The Driving Agent Had to Rehearse Its Effects
Simulation-grounded action estimates improved collision, displacement and reward measures across four highway scenarios.
Summary
Simulation-grounded action estimates improved collision, displacement and reward measures across four highway scenarios.
GAPL asks a language model to estimate an action’s effects, checks those estimates against simulator rollouts and distills the grounded result into a reinforcement-learning policy. Across four Highway-env scenarios, the authors report lower collision and displacement errors plus a 1.44 average reward gain over their baselines. These are simulator results and do not establish road readiness or safety certification.
