Foreword
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 documents 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 278,
Intelligent transport systems, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This first edition of ISO 17573-2 cancels and replaces ISO/TS 17573-2:2020, which has been technically
revised.
The main changes are as follows:
— conversion of this document from a technical specification to an international standard;
— several new terms (e.g. mode of transport, true positive and negative events) have been added.
A list of all parts in the ISO 17573 series can be found on the ISO website.

Introduction
This document is a part of the ISO 17573 series that defines the system architecture for vehicle-related
tolling. ISO 17573-1 gives a reference model for the system architecture. ISO 17573-3 provides a data
dictionary that contains the definitions of ASN.1 (data) types and the associated semantics.
This document provides a collection of terms and definitions within the field of electronic fee collection
(EFC) and road user charging that are used in the different documents published in ISO and CEN under the
general title “Electronic fee collection”.
This document is based on guidelines from the relevant ISO International Standards for terminologies, in
particular ISO 704 and ISO 1087. Experiences were also drawn from more general work done on terminology,
[30]
in particular from the work on the Nordic ITS terminology.
This document is intended to be used as a reference by editors of documents in EFC and in related areas of
standardization (such as intelligent transport systems, ITS). It may also be used by the general public and
the stakeholders in EFC as a vocabulary, fostering a harmonized language when describing EFC systems in
specifications, reports and other texts.
As this document is the main source for standardized EFC terms, any previous source references have
intentionally been left out. However, source references are listed in the Bibliography.
It is foreseen that the terminology work on EFC terms will continue with addition of new terms, revision of
existing terms and replacement or deletion of deprecated terms.
