AI detects stealthy false data in urban pedestrian flow sensors

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method using physics-constrained digital twins to detect stealthy false data injection in urban pedestrian flow sensing systems. This approach models directed flows on a street graph and assimilates counts via a learned localized gain, trained against a flow conservation residual. The system combines this residual with adaptive conformal calibration for alarm setting, demonstrating a significant reduction in the impact of compromised devices on estimated flow fields, even with a substantial portion of the fleet compromised. AI

IMPACT This research could improve the reliability of urban sensing systems, impacting city planning and safety operations.

    Physics-Constrained Digital Twins for Sensor Integrity in Urban Pedestrian Flow: Detecting Stealthy False Data Injection with Conformal Guarantees

    arXiv:2609.17635v1 Announce Type: new Abstract: City pedestrian counting systems now feed economic indicators, planning decisions and safety operations, yet the twins built on top of them treat the incoming stream as ground truth. We study what happens when it is not. We formalis…
