The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Grounded in a microscopic stochastic model, the framework offers a scalable and privacy-preserving approach to analyzing urban soft mobility dynamics.

C2weakest assumption

That the newly introduced attendance functions accurately capture real spatio-temporal travel patterns between activities and that the Poisson model plus maximum-likelihood estimation can reliably recover subpopulation sizes from aggregated counts.

C3one line summary

A macroscopic activity-based model estimates urban active mobility from aggregated non-intrusive sensor counts by introducing attendance functions, modeling data as Poisson, and using maximum likelihood with an EM algorithm.
