Researchers have developed Enactor, a novel generative model designed for closed-loop microsimulation of signalized intersections. Unlike traditional simulators that use hand-crafted models, Enactor employs an actor-centric transformer architecture to predict vehicle movements, capturing more nuanced interactions. The model was trained using a closed-loop curriculum and demonstrated superior performance in recovering SUMO data distributions for speed and travel time, significantly reducing red-light violations compared to existing transformer baselines.
