Diffusion model fuses urban data for improved commuting flow prediction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SEDAN, a novel conditional diffusion model designed to generate Origin-Destination (OD) matrices for commuting flows across different cities. This model represents cities as attributed graphs, incorporating demographic and point-of-interest features along with spatial structure like adjacency and distance matrices. SEDAN fuses semantic and spatial information to create more accurate and generalizable OD matrices, outperforming existing methods by 7.38% in RMSE on U.S. city datasets. AI

IMPACT Provides a more accurate and generalizable method for urban planning and resource allocation by improving OD matrix generation.

    Fusing Urban Structure and Semantics: A Conditional Diffusion Model for Cross-City OD Matrix Generation

    arXiv:2605.00938v1 Announce Type: new Abstract: Accurate modeling of commuting flows is important for urban governance, traffic planning, and resource allocation. However, the combined influence of individual intentions, geographic constraints, and social dynamics leads to consid…
