Data and standards
Curb Data Specification (CDS)
Spécification des données du curb (CDS)
Curb Data Specification (CDS) is an open standard maintained by the Open Mobility Foundation for exchanging curb locations, regulations, activity, and related metrics. Its APIs support consistent communication between public agencies and other participants, with implementation scope determined by the functions and version an organization actually adopts.
Understanding the term
CDS separates the description of permitted use from observed events and calculated metrics. An implementation should identify supported endpoints and versions rather than claim compatibility from a single exported map.
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.
