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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
⎯ an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
⎯ an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
ISO/TS 17575-3 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 278, Road transport and traffic telematics, in collaboration with Technical Committee ISO/TC 204,
Intelligent transport systems, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
ISO/TS 17575 consists of the following parts, under the general title Electronic fee collection — Application

Introduction
Autonomous systems
This part of ISO/TS 17575 is part of a series of specifications defining the information exchange between the
Front End and the Back End in Electronic Fee Collection (EFC) based on autonomous on-board equipment
(OBE). EFC systems automatically collect charging data for the use of road infrastructure including motorway
tolls, zone-based fees in urban areas, tolls for special infrastructure like bridges and tunnels, distance-based
charging, and parking fees.
Autonomous OBE operates without relying on dedicated road-side infrastructure by employing wide-area
technologies such as Global Navigation Satellite Systems (GNSS) and Cellular Communications Networks
(CN). These EFC systems are referred to by a variety of names. Besides the terms autonomous systems and
GNSS/CN systems, also the terms GPS/GSM systems and wide-area charging systems are in use.
Autonomous systems use satellite positioning, often combined with additional sensor technologies such as
gyroscopes, odometers and accelerometers, to localize the vehicle and to find its position on a map containing
the charged geographic objects, such as charged roads or charged areas. From the charged objects, the
vehicle characteristics, the time of day and other data that are relevant for describing road use, the tariff and
ultimately the road usage fee are determined.
Some of the strengths of the autonomous approach to electronic fee collection are its flexibility, allowing the
implementation of almost all conceivable charging principles, and its independence from local infrastructure,
thereby predisposing this technology towards interoperability across charging systems and countries.
Interoperability can only be achieved with clearly defined interfaces, which is the aim and justification of
ISO/TS 17575.
Business architecture
This part of ISO/TS 17575 complies with the business architecture defined in ISO 17573. According to this
architecture, the Toll Charger is the provider of the road infrastructure and, hence, the recipient of the road
usage charges. The Toll Charger is the actor associated with the Toll Charging role. See Figure 1.

Service Providers issue OBE to the users of the road infrastructure. Service Providers are responsible for
operating the OBE that will record the amount of road usage in all toll charging systems the vehicle passes
through and for delivering the charging data to the individual Toll Chargers. In general, each Service Provider
delivers charging data to several Toll Chargers, as well as each Toll Charger in general receives charging
data from more than one Service Provider. Interoperability Management in Figure 1 comprises all
specifications and activities that in common define and maintain a set of rules that govern the overall toll
charging environment.
Technical architecture
The technical architecture of Figure 2 is independent of any particular practical realization. It reflects the fact
that some processing functionalities can either be allocated to the OBE or to an associated off-board
component (Proxy). An example of processing functionality that can be realized either on- or off-board is
map-matching, where the vehicle locations in terms of measured coordinates from GNSS are associated to
geographic objects on a map that either resides on- or off-board. Also tariffication can be done with OBE tariff
tables and processing, or with an off-board component.

Figure 2 — Assumed technical architecture and interfaces
The combined functionality of OBE and Proxy is denoted as Front End. A Front End implementation where
processing is predominately on OBE-side is known as a smart client (or intelligent client, fat client) or
edge-heavy. A Front End where processing is mostly done off-board is denoted as thin-client or edge-light
architecture. Many implementations between the “thin” and “thick” extremes are possible, as depicted by the
gradual transition in the wedges in Figure 2. Both extremes of architectural choices have their merits and are
one means where manufacturers compete with individual allocations of functionality between on-board and
central resources.
Especially for thin client OBE, manufacturers might devise a wide variety of optimizations of the transfer of
localization data between OBE and off-board components, where proprietary algorithms are used for data
reduction and data compression. Standardization of this transfer is neither fully possible nor beneficial.
Location of the specification interface
In order to abstract from, and become independent of, these architectural implementation choices, the primary
scope of ISO/TS 17575 is the data exchange between Front End and Back End (see the corresponding dotted
line in Figure 2). For every toll regime, the Back End will send context data, i.e. a description of the toll regime
in terms of charged objects, charging rules and, if required, the tariff scheme to the Front End, and will receive
usage data from the Front End.

ISO/TS 17575-3:2011(E)
It has to be noted also that the distribution of tasks and responsibilities between Service Provider and Toll
Charger will vary individually. Depending on local legal situation, Toll Chargers will require “thinner” or
“thicker” data, and might or might not leave certain data processing tasks to Service Providers. Hence, the
data definitions in ISO/TS 17575 may be useful on several interfaces.
ISO/TS 17575 also provides for basic media-independent communication services that may be used for
communication between Front End and Back End, which might be line-based or an air-link, and can also be
used for the air-link between OBE and central communication server.
The parts of ISO/TS 17575
Part 1: Charging, defines the attributes for the transfer of usage data from the Front End to the Back End. The
required attributes will differ from one Toll Charger to another, hence, attributes for all requirements are
offered, ranging from attributes for raw localization data, for map-matched geographic objects and for
completely priced toll transactions.
Part 2: Communication and connection to lower layers, defines basic communication services for data transfer
over the OBE air-link or between Front End and Back End.
Part 3: Context Data, defines the data to be used for a description of individual charging systems in terms of
charged geographical objects and charging and reporting rules. For every Toll Charger's system, attributes as
defined in Part 3 are used to transfer data to the Front End in order to instruct it which data to collect and
report.
Part 4: Roaming, defines the functional details and data elements required to operate more than one EFC
regime in parallel. The domains of these EFC regimes may or may not overlap. The charge rules of different
overlapping EFC regimes can be linked, i.e. they may include rules that an area pricing scheme will not be
charged if an overlapping toll road is used and already paid for.

ISO/TS 17575-3:2011(E)
In ISO/TS 17575, context data is the description of the properties of a single instance of an EFC context. This
single instance of an EFC context operates according to one of the basic tolling principles such as
⎯ road sectioned tolling,
⎯ area pricing according to travelled distance,
⎯ area pricing according to the time,
⎯ cordon pricing.
EFC context data comprise a set of rules for charging, including the description of the charged network, the
charging principles, the liable vehicles and a definition of the required contents of the charge report. This set
of rules is defined individually for each EFC context according to local needs.
This part of ISO/TS 17575 contains the definitions of the above listed type of data.
Only a Front End configured with the context data necessary for the respective EFC context is able to be used
for charging processes.
The following data definitions are in this part of ISO/TS 17575:
⎯ data providing toll context overview information;
⎯ data providing tariff information (this includes definitions of required tariff determinants like vehicle
parameters, time classes and others);
⎯ data providing context layout information;
⎯ data providing reporting rules information.
In case one EFC domain cannot be described with a single set of context data, several of these context data
are used. ISO/TS 17575-4 defines the parallel operation of more than one EFC context and how to handle
interdependencies.
Applicatory needs covered by ISO/TS 17575
⎯ The parts of ISO/TS 17575 are compliant with the architecture defined in ISO 17573.
⎯ The parts of ISO/TS 17575 support charges for use of road sections (including bridges, tunnels, passes,
etc.), passage of cordons (entry/exit), and use of infrastructure within an area (distance, time).
⎯ The parts of ISO/TS 17575 support fee collection based on units of distance or duration, and based on
occurrence of events.
⎯ The parts of ISO/TS 17575 support modulation of fees by vehicle category, road category, time of usage,
and contract type (e.g. exempt vehicles, special tariff vehicles, etc.)
⎯ The parts of ISO/TS 17575 support limiting of fees by a defined maximum per period of usage.
⎯ The parts of ISO/TS 17575 support fees with different legal status (e.g. public tax, private toll).
⎯ The parts of ISO/TS 17575 support differing requirements of different Toll Chargers, especially in terms of
⎯ geographic domain and context descriptions,
⎯ contents and frequency of charge reports,
