==== IVIM (Infrastructure to Vehicle Information Message) ====
IVIMs carry **road sign and infrastructure information** (ETSI TS 103 301 / ISO 19321) — essentially electronic road signage.

Typical contents:
  - variable speed limits from overhead gantries
  - lane closures and lane management
  - warnings shown on variable message signs
  - sign information for a stretch of road

IVIMs are sent by [[en:c-its:rsu|RSUs]], e.g. on the ASFINAG motorway network, and are valid for a defined section of road rather than a single point.
