This document provides information and specifications enabling management of road traffic in controlled zones applying geofencing. Specifically, this document provides — a “Controlled Zone Data Dictionary” (CZDD) for management of controlled zones providing an extendible toolkit that regulators can use e.g. to inform potential CZ users, e.g. vehicles, about — the CZ area, i.e. the geographical boundaries of the CZ; — CZ access conditions including exempts; — time windows indicating when these CZ access conditions are applicable, allowing the potential CZ users to select an appropriate routing, either by pre-trip planning or ad hoc re-routing, — and illustrations and guidelines on how to use this toolkit. The toolkit is designed in compliance with the general ITS station and communications architecture specified in ISO 21217 , and optionally applicable C-ITS protocols and procedures, e.g. ISO 22418:2018  on “Service Announcement”, EN ISO 18750 on the “Local Dynamic Map”, and EN ISO 17419  on globally unique identifiers. Enforcement is out of scope of this document.
