Anticipatory generation. A new arXiv paper introduces an anticipatory generative model for road-network trajectories, targeting urban applications such as traffic management and urban planning. The abstract frames trajectory generation as a core need for these domains.
The paper notes that vehicle movement along road segments is largely deterministic, whereas transitions at intersections are the less predictable part of a trajectory. The title, Looking Ahead and Back, suggests the model uses both future and past context to generate realistic paths.
The abstract is brief and does not specify the model architecture or evaluation details. The contribution, as described, is the anticipatory framing itself, which treats trajectory generation as a task that requires looking in both temporal directions.
