Intelligent transport systems — Mobility integration — 'Controlled zone' management for urban vehicle access restrictions (UVARs) using C-ITS
This document provides information and specifications on the management of road traffic in controlled zones (CZ) through the application of geofencing. Specifically, this document specifies a “Controlled Zone Data Dictionary” (CZDD) for management of controlled zones, and provides an extendible toolkit that regulators can use, for example, to inform potential CZ users (e.g. vehicles) about: — the CZ area, i.e. the geographical boundaries of the CZ; — CZ access conditions including exemptions; — time windows indicating when these CZ access conditions are applicable. This allows potential CZ users to select an appropriate routing, either by pre-trip planning or ad hoc re-routing. This document also provides illustrations and guidelines on how to use this toolkit. The toolkit is designed in accordance with the general ITS station and communications architecture specified in ISO 21217, and with optionally applicable C-ITS protocols and procedures, e.g. ISO 22418 on “Service Announcement”, ISO 18750 on the “Local Dynamic Map”, and ISO 17419 on globally unique identifiers. Cybersecurity provision can be provided through conformance to ISO 21177. Enforcement is out of scope of this document.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
This document is part of a set of standards from ISO/TC 204 related to ITS Mobility Integration/Urban ITS
(U-ITS). It provides an internationalized, version of CEN/TS 17380 for management of vehicles in a “Controlled
Zone” (CZ). It is primarily designed for urban vehicle access restrictions (although it is also appropriate for
similar restriction control in any road system context). Its technical provisions are interoperable with CEN/
TS 17380. This document aims to complement CEN/TS 16157-11.
A CZ is a geographically contained physical area for which access restriction conditions are applicable for all
or some categories of vehicle or user, at all or specified times.
Management of traffic in a CZ is important for the following reasons, amongst others.
— As cities and urban complexes expand, and the significant trend of movement from rural areas to cities
continues around the world, pollution and congestion in these urban areas is becoming an increasingly
significant problem. Traffic, i.e. vehicle movements within the urban complex, is a source of pollution.
NOTE Other causes of pollution include air conditioning, central heating systems, coal and wood burning
heating, factories, etc.
— Jurisdictions can wish to control certain issues, such as movement of vehicles in cities producing traffic
congestion and overcrowding on public transport at peak periods, as this can enable better management
of traffic flow.
A CZ, also referred to as an “Urban Vehicle Access Restriction” (UVAR) zone, is a zone of enactment of
one or more traffic restrictions to adhere to a permanent or temporary regulation applicable in a defined
geographical area. These restrictions are frequently referred to as “Urban Vehicle Access Regulations”.
It is recognized that different jurisdictions will design and introduce their own CZ paradigms of different
method and construct. However, regardless of the goal to be achieved or the political objective, the basic
technical requirements for managing road traffic in a CZ are similar, and the basic methodologies are the same.
The methodology specified in this document is often referred to as “geofencing”, i.e. the creation of a virtual
geographic boundary.
Management of CZs can be achieved using data frames from the data dictionary (CZDD) specified in this
document, and data frames contained in the in-vehicle information (IVI) data dictionary specified in
ISO/TS 19321. Data frames specified in this document and in ISO/TS 19321 constitute Application Data Units.
While the CZDD is dedicated to CZs, the IVI data dictionary is of a general nature. There is no strict one-to-
one mapping between the CZDD data frames and the data frames from the IVI data dictionary related to CZ.
This document identifies two possible methods for transmitting CZ data frames:
1) a method based on the general CZ message being part of the general TMS message set (see the concept
of ITS messages and ITS message sets specified in ISO 17419, which does not require a specific
communications technology);
2) the IVI message method, which is specified in ETSI TS 103 301.
