Geofencing
Géorepérage
Geofencing is the use of a virtual geographic boundary to associate rules, alerts, or actions with a location. Curb and shared-mobility systems may use geofences for permitted areas or operating restrictions, but boundary accuracy and device positioning limits affect how reliably those rules can be applied.
Understanding the term
A geofence is not a physical barrier. Allow for positioning uncertainty near narrow sidewalks, adjacent streets, and building edges before interpreting a boundary crossing as noncompliance.
An implementation should document its version, identifiers, time conventions, geographic accuracy, and supported fields. Test representative exchanges between the actual participating systems, including exceptions and updates. Assign responsibility for correcting discrepancies between published information, legal records, and the street. Collect only information needed for a defined purpose and apply suitable access and retention controls. A successful technical exchange does not by itself prove that the data is current, legally authoritative, or suitable for enforcement.
