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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17573 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, in collaboration
with Technical Committee CEN/TC 278, Road transport and traffic telematics.
This second edition cancels and replaces the first edition (ISO/TS 17573:2003), which has been technically
revised.
Introduction
The widespread use of tolling requires provisions for users of vehicles that are roaming through many different
toll domains. Users should be offered a single contract for driving a vehicle through various toll domains and
those vehicles require on-board equipment (OBE) that is interoperable with the toll system in the various toll
domains. In Europe, for example, this need has been officially recognized and legislation on interoperability
has already been adopted. See EFC Directive 2004/52/EC. There is a commercial and economic justification
both in respect to the OBE and the toll systems for standards enabling interoperability.
In addition to other standards, there is also a further need for a system architecture that
⎯ provides an architectural “umbrella” for other EFC standards in terms of a common definition of terms and
concepts, basic system functionalities, and structure;
⎯ provides a common terminology which enables its users
⎯ to improve the quality of specifications to be used in an international market,
⎯ to reduce the risk for different interpretations of specifications (purchaser) and descriptions (supplier),
⎯ to simplify the communication between experts from different continents, and
⎯ to enhance the potential use of other EFC standards;
⎯ defines a common framework, that enables both
⎯ identification of potential activities subject to standardization, and
⎯ maintenance of a common and consistent view of the whole area;
⎯ defines the boundaries between the EFC and the external world;
⎯ identifies all architectural objects that are within the EFC boundaries;
⎯ provides a basic understanding of EFC, EFC interoperability, and the EFC services being offered.
The previous edition of this International Standard was based on a conceptual model defined in ISO/TS 14904.
Since then, ideas on conceptual models have evolved in several regional projects and implementations, e.g.
in Japan and Europe. Those new models have been detailed to a further extent compared to
ISO/TS 17573:2003 and are closer to real-life implementations. This International Standard is based on these
new conceptual models and uses the associated terms and definitions. A comparison between
ISO/TS 17573:2003 and this edition is shown in Annex B.
Although there are many differences, collecting tolls for vehicles can be to some extent compared with
collecting fares for public transport. Architectural harmonization of the collection of fees and fares can be
desirable from a policy and from a user point of view. In the past ISO 24014-1 (prepared by CEN/TC 278
WG 3, Public Transport) used ISO/TS 17573:2003 as a starting point for their work. This International
Standard has benefited from that and has also taken ISO 24014-1 into account.
In this International Standard the open distributed processing (ODP) standard is used for the description of the
architecture.
The ODP standard gives a vocabulary and modelling tools to see the architecture of a system from different
perspectives (viewpoints), in order to cover, for example, hardware components as well as network protocols

or interfaces or roles and general policies of the system itself. This is accomplished using different sets of
concepts and terminologies, each one of those expressed as a viewpoint language. A complete description of
a real system can only be achieved when all viewpoint models are designed. This allows for a clear separation
of concerns and an easier way to define a system. A brief description of the ODP concepts can be found in
Annex A.
This International Standard gives a description of the architecture of the toll systems environment from the
enterprise viewpoint. In addition, this International Standard defines the foundations of the information
viewpoint by defining information interactions and general information objects,
