Electronic fee collection — Application interface definition for autonomous systems — Part 1: Charging

ISO 17575-1:2016 defines the format and semantics of the data exchange between a Front End (OBE plus optional proxy) and corresponding Back Ends in autonomous toll schemes. It defines the data elements that are used to generate charge reports containing information about the road usage of a vehicle for certain time intervals, sent from the Front End to the Back End. It also defines the data that can be used to re-configure the ongoing process of gathering charge relevant information in the Front End. The scope is shown in Figure 1. The constitution of the charge report is dependent on configuration data that are assumed to be present in the Front End. The assembly of charge reports can be configured for each individual toll scheme according to local needs. Charge reports generated in accordance with this part of ISO 17575 are consistent with the requirements derived from the architectural concept defined in ISO 17573:2010. The definitions in ISO 17575-1:2016 comprise - reporting data, i.e. data for transferring road usage data from Front End to Back End, including a response from the Back End towards the Front End, - data for supporting security mechanisms, - contract data, i.e. data for identifying contractually essential entities, - road usage data, i.e. data for reporting the amount of road usage, - account data for managing a payment account, - versioning data, and - compliance checking data, i.e. data imported from ISO 12813:2015, which are required in compliance checking communication. Annex A contains the data type specifications using ASN.1 notation. The protocol implementation conformity statements (PICS) proforma are provided in Annex B. Annex C provides a graphical presentation of the structure of the data elements described in Clause 7. Annex D provides information on how this part of ISO 17575 can be used in EETS environment and how the requirements that are specified in the EU-Decision 2009/750 are addressed by this standard.

Perception du télépéage — Définition de l'interface d'application pour les systèmes autonomes — Partie 1: Imputation

ISO 17575-1:2016 définit le format et la sémantique pour l'échange de données entre un système frontal (OBE plus proxy optionnel) et des systèmes centraux correspondants dans des systèmes de péage autonomes. Elle définit les éléments de données utilisés pour générer des rapports de perception contenant des informations sur l'utilisation du réseau routier par un véhicule pendant des intervalles de temps donnés, envoyées du système frontal au système central. Elle définit également les données qui peuvent être utilisées pour reconfigurer le processus de collecte permanente des informations d'imputation pertinentes dans le système frontal. Son domaine d'application est représenté à la Figure 1. La constitution d'un rapport de perception dépend des données de configuration supposées être présentes dans le système frontal. L'ensemble des rapports de perception peut être configuré pour chaque système de péage individuel selon les besoins locaux. Les rapports de perception générés conformément à la présente partie de l'ISO 17575 concordent avec les exigences dérivées du concept architectural défini dans l'ISO 17573:2010. Dans l'ISO 17575-1:2016, les définitions comprennent - les données des rapports, c'est-à-dire les données permettant de transférer des données d'utilisation du réseau routier d'un système frontal à un système central, y compris une réponse du système central au système frontal, - les données de prise en charge des mécanismes de sécurité, - les données contractuelles, c'est-à-dire les données permettant d'identifier les entités contractuellement essentielles, - les données d'utilisation du réseau routier, c'est-à-dire les données permettant de communiquer l'utilisation qui est faite du réseau routier, - les données de compte pour gérer un compte de paiement, - les données de contrôle des versions, - les données de contrôle de conformité, c'est-à-dire les données importées de l'ISO 12813:2015, qui sont requises dans les communications de contrôle de conformité. L'Annexe A donne la spécification du type de données dans la notation ASN.1. Les formulaires PICS (déclaration de conformité d'implémentation de protocole) sont fournis en Annexe B. L'Annexe C comprend une représentation graphique de la structure des éléments de données décrits à l'Article 7. L'Annexe D fournit des informations sur la façon dont la présente partie de l'ISO 17575 peut être appliquée dans un environnement SET et sur la manière dont la présente norme couvre les exigences spécifiées dans la Décision de la Commission 2009/750.

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.

ISO/DIS 17575-1
Introduction
Autonomous systems
This part of ISO 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 17575.
Business architecture
This part of ISO 17575 complies with the business architecture defined in the draft of the International
Standard 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.
Figure 1 - The role-based model underlying this Standard
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
ISO/DIS 17575-1
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 tariff determination 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 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/DIS 17575-1
It has to be noted also that the distribution of tasks and responsibilities between Service Provider and Toll
Charger will vary individually. Depending on the 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 17575 may be useful on several interfaces.
ISO 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 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 charging scheme will not be
charged if an overlapping toll road is used and already paid for.

DRAFT INTERNATIONAL STANDARD ISO/DIS 17575-1

Electronic fee collection — Application interface definition for
autonomous systems — Part 1: Charging
1 Scope
This part of ISO 17575 defines the format and semantic of the data exchange between a Front End (OBE plus
optional proxy) and corresponding Back Ends in autonomous toll regimes. This part of ISO 17575 deals with
the definition of the data elements used to report charging details from the Front End to the Back End and to
receive data which can be used to re-configure the ongoing process of gathering charge relevant information
in the Front End.
The constitution of the charge report is dependent on configuration data that are assumed to be present in the
Front End. The assembly of charge reports can be configured for each individual toll regime according to local
needs. Charge reports generated in accordance with this part of ISO 17575 are consistent with the
requirements derived from the current architectural concept favoured in the relevant standardization bodies as
defined in ISO 17573.
The data defined in this part of ISO 17575 are used to generate charge reports that contain information about
the road usage of a vehicle for certain time intervals. The contents of these charge reports might vary between
toll regimes. A toll regime comprises a set of rules for charging, including the charged network, the charging
principles, the liable vehicles and a definition of the required contents of the charge report.
The data defined in this part of ISO 17575 are exchanged using an open definition of a communication stack
as defined in ISO 17575 2.
The definitions in this part of ISO 17575 comprise:
¾ reporting data, i.e. data for transferring road usage data from Front End to Back End, including a response
from the Back End towards the Front End;
¾ contract data, i.e. data for identifying contractually essential entities;
¾ road usage data, i.e. data for reporting the amount of road usage;
¾ account data for managing a payment account;
¾ versioning data;
¾ compliance checking data, i.e. data imported from ISO 12813, which are required in Compliance
Checking Communications.

5 Procedural requirements
5.1 General
This part of ISO 17575 is intended to be used in autonomous toll systems set up according to the overall
architecture described in ISO 17573.
It defines the format and semantics of charge reports and charge report responses, which are part of the end-
to-end information flow.
On-board equipment collects data on the road usage of an individual vehicle. These data are aggregated and
processed regarding their relevance for charging either in the on-board equipment or in a proxy. The
combination of on-board equipment and proxy is referred to as a Front End.
This part of ISO 17575 defines the data required for communicating charge-relevant road usage data for an
individual vehicle from the Front End to the Back End. The Front End shall accumulate road usage data into
charge reports and send the charge reports to the Back End. The Back End shall confirm reception of a
charge report (ChargeReport) with a charge report response (ChargeReportResponse).
5.2 Charge report configuration
All data elements comprising the attribute charge report are coded as optional (except for the
usageStatementList, which ultimately also contains only optional elements).
4 © ISO 2013 – All rights reserved

ISO/DIS 17575-1
For every toll regime, the Back End sends context data to the Front End. Context data is a description in terms
of charge objects, charging rules and, if required, the tariff scheme.
Toll context data defines which data elements shall be present and which shall not. The Back End shall
communicate the toll context data defining the requested charge report contents to the Front End before the
on-board equipment is expected to collect road usage data. Upon reception of toll context data the Front End
shall start to collect, process and accumulate road usage data into charge reports as requested. Toll context
data also define upon which events charge reports shall be communicated.
NOTE 1 The charge report content requirements defined by the toll context data allow setting the report contents as
required by the properties of the toll regime. These properties include the basic toll system types like:
¾ road section tolling (the charge relevant parameter is the sum of the road section lengths or tariff used by
the vehicle);
¾ area charging (the charge relevant parameter is either the distance driven inside the area or the time
stayed inside the area);
¾ cordon charging (the charge relevant parameter is the event of crossing the cordon around an area).
NOTE 2 Depending on local needs, Toll Chargers may require more or less processed data to varying levels of detail.
Privacy considerations, enforcement approach and legal nature of the charge will also influence the choices agreed
between toll charger and toll service provider regarding the requested contents of charge reports.
Charge reports support:
¾ reporting a list of charge objects that are declared as being used by the vehicle including associated tariff
modifiers; this report may or may not include the calculated fee or tax;
¾ reports of road usage sessions within a single set of tariff modifiers; this report may or may not include the
calculated fee or tax;
¾ report of contiguous sessions on a toll road or area where just the aggregated fee and the associated
reference time is reported;
¾ reports where only the total fee within a predefined report period is forwarded (in this case it is anticipated
that other means, outside the scope of this part of ISO 17575, are used to allow a certain degree of
validation of the charging process);
¾ any combination of the reports listed above.
5.3 Charge report response
The Back End shall respond to every received charge report with a charge report response. Which of the
optional elements of the attribute ChargeReportResponse are present is not defined in this part of ISO 17575.
NOTE The contents of the charge report response depend on the make and type of the Front End and on application
software of the Front End and Back End as defined by the business requirements of the individual Service Provider. This
part of ISO 17575 only offers data elements for the response but does not impose restrictions upon the implementation
and business choices by requiring mandatory content.
6 Data elements
6.1 Introduction
Data elements are grouped in logical groups for readability only.
ISO/DIS 17575-1
The data group Reporting contains the main data elements of the charge report communication. These
elements are the top level, overarching data structures containing all data elements described in this part of
ISO 17575.
The data group General contains data elements and types which are not explicitly part of other groups.
The data group Contract contains data elements and types related to road user contract information.
The data group Usage contains the information necessary to describe the usage of infrastructure causing
eligibility for fees. These data are necessary for calculating the charges and for setting up correct bills and for
settling disputes. The main data elements of this group present in the charge report and charge report
response are respectively usageStatementList and dataReceived.
The data group Account contains the elements necessary to ensure that the correct account (and road user)
is charged with the toll fees. The elements in the group Account are used for managing road user accounts in
the Front End. These Front End accounts can contain the following types of data.
¾ Credit: the account holds a value corresponding to a monetary amount.
¾ Distance: the account holds a value representing a distance.
¾ Time: the account holds a value representing a point in time.
¾ Duration: the account holds a value representing time duration.
¾ Event: the account holds a value representing a number of events.
The main data elements of this group present in the charge report and charge report response are
respectively accountStatus and accountUpdate.
NOTE The kind of event counted in the respective option of the account data type is left to the implementation.
The data group Versioning contains data elements for version control of elements on the OBE.
The data group Compliance Checking provides information exchanged in compliance checking
communication (CCC), as defined in ISO 12813. Some of the data exchanged by CCC are already covered by
other data elements, but for complete information about the content of CCC the data in this group are
necessary.
6.2 Reporting
The two data types ChargeReport and ChargeReportResponse described in this subclause cover the
complete charge report communication.
The data type ChargeReport comprises the following data elements:
6 © ISO 2013 – All rights reserved

ISO/DIS 17575-1
¾ obeId,
¾ vehicleLPNr,
¾ paymentMeans,
¾ serviceProviderContract,
¾ tollCharger,
¾ timeOfReport,
¾ reportPeriod,
¾ versionInfo,
¾ usageStatementList,
¾ vatForThisSession,
¾ accountStatus,
¾ transactionCounter,
¾ mileage,
¾ cccAttributes,
¾ authenticator.
Those are the basic data elements for charge communication. A data element of the type ChargeReport is
sent by the Front End whenever it is necessary to transmit charge data to the Back End.
The report contains the necessary data for identifying the (already registered) OBE and contract. It relays the
information on usage of chargeable infrastructure by the vehicle and provides additional information for
plausibility checks and accounting procedures (e.g. VAT calculations).
The data elements contained in this structure pertain to logical data groups and are detailed in the rest of
Clause 6.
In response to a charge report, the Back End answers with a data element of the type
ChargeReportResponse. This data type consists of the following components:
¾ reportRecipientId,
¾ dataReceived,
¾ versionsResponse,
¾ obeStatusForDriver,
¾ accountUpdate,
¾ responseAuthenticator.
These data provide a confirmation of the data reception at the application level. In addition feedback to the
Front End (e.g. request for updates, change in OBE status) is provided.
The data types and elements contained in this structure and the ones constituting those pertain to logical data
groups and are detailed below.
6.3 General
6.3.1 vehicleDescription
The data element vehicleDescription contains a list of characteristics (vehicleLPNr, axles, class,
dimensions, specificCharacteristics, ladenWeight, weightLimits) of the vehicle. The data types of
these elements are defined in and imported from ISO 14906.
6.3.2 timeOfReport
The data element timeOfReport gives the date and time when the charge report was compiled for
transmission. The corresponding data type DateAndTime is defined in and imported from ISO 14906.
NOTE All data elements giving time information use the local time at the location of the vehicle.
ISO/DIS 17575-1
6.3.3 reportPeriod
The data element reportPeriod gives the time period covered by the respective ChargeReport.
6.3.4 vatForThisSession
The data element vatForThisSession contains the aggregated VAT for the fees communicated in the
respective charge report. Its associated data type is PaymentFee, which is defined in and imported from
ISO 14906.
6.3.5 transactionCounter
The data element transactionCounter gives the number of the current charge report. This counter shall be
incremented by the Front End after compilation of a charge report, facilitating distinction between charge
reports. In the case of overflow the counter starts again at 0.
6.3.6 mileage
The data element mileage contains the reading of an internal mileage counter of type Distance. The counter
shall start at 0 for a new OBE and continuously count all vehicle mileage while the OBE is active; the counter
shall restart from zero in case of overflow (i.e. when reaching the maximum value).
6.3.7 Distance
The data type Distance contains distance values. The first element (dist) is an integer containing the
distance value itself, the second (disUnit) is used for defining the unit of distance used. It can have the
values kilometres, miles and metres.
6.3.8 Position
The data type position defines a geographical position, with the elements longitude and latitude as
defined in ISO 6709.
6.3.9 Period

Introduction
0.1 Autonomous systems
ISO 17575 is a series of standards 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 Networks (CN). These
EFC systems are referred to by a variety of names. In addition to the terms autonomous systems and
GNSS/CN systems, the terms GPS/GSM systems and wide-area charging systems are also 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.
Two 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 17575.
0.2 The parts of ISO 17575
Part 1: Charging, defines the attributes for the transfer of usage data from the Front End to the Back End.
The contents of charge reports might vary between toll regimes, 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. A toll regime comprises a set of rules for charging, including the
charged network, the charging principles, the liable vehicles and a definition of the required contents of
the charge report.
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. The data defined in this part of
ISO 17575-1 and ISO 17575-3 can but need not be exchanged using the communication stack as defined
in ISO 17575-2.
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 ISO 17575-3 are used to transfer data to the Front End in order to instruct it on
which data to collect and report.
0.3 Application needs covered by ISO 17575
The ISO 17575-series of standards
— is compliant with the architecture defined in ISO 17573:2010,
— supports charges for use of road sections (including bridges, tunnels, passes, etc.), passage of
cordons (entry/exit) and use of infrastructure within an area (depending on distance, time),
— supports fee collection based on units of distance or duration, and based on occurrence of events,
— supports modulation of fees by vehicle category, road category, time of usage and contract type (e.g.
exempt vehicles, special tariff vehicles, etc.),
— supports limiting of fees by a defined maximum per period of usage,
vi © ISO 2016 – All rights reserved

— supports fees with different legal status (e.g. public tax, private toll),
— supports differing requirements of different toll chargers, especially in terms of
— geographic domain and context descriptions,
— contents and frequency of charge reports,
— feedback to the driver (e.g. “green” or “red light”), and
— provision of additional detailed data on request, e.g. for settling of disputes,
— supports overlapping geographic toll domains,
— supports adaptations to changes in
— tolled infrastructure,
— tariffs, and
— participating toll schemes, and
— supports the provision of trust guarantees by the toll service provider to the toll charger for the
data originated from the Front End.

for autonomous systems —
Part 1:
Charging
1 Scope
This part of ISO 17575 defines the format and semantics of the data exchange between a Front End
(OBE plus optional proxy) and corresponding Back Ends in autonomous toll schemes. It defines the data
elements that are used to generate charge reports containing information about the road usage of a
vehicle for certain time intervals, sent from the Front End to the Back End. It also defines the data that
can be used to re-configure the ongoing process of gathering charge relevant information in the Front
End. The scope is shown in Figure 1.
The constitution of the charge report is dependent on configuration data that are assumed to be present
in the Front End. The assembly of charge reports can be configured for each individual toll scheme
according to local needs. Charge reports generated in accordance with this part of ISO 17575 are
consistent with the requirements derived from the architectural concept defined in ISO 17573:2010.
The definitions in this part of ISO 17575 comprise
— reporting data, i.e. data for transferring road usage data from Front End to Back End, including a
response from the Back End towards the Front End,
— data for supporting security mechanisms,
— contract data, i.e. data for identifying contractually essential entities,
— road usage data, i.e. data for reporting the amount of road usage,
— account data for managing a payment account,
— versioning data, and
— compliance checking data, i.e. data imported from ISO 12813:2015, which are required in compliance
checking communication.
Annex A contains the data type specifications using ASN.1 notation.
The protocol implementation conformity statements (PICS) proforma are provided in Annex B.
Annex C provides a graphical presentation of the structure of the data elements described in Clause 7.
Annex D provides information on how this part of ISO 17575 can be used in EETS environment and how
the requirements that are specified in the EU-Decision 2009/750 are addressed by this standard.

5 Architectural considerations
5.1 Business architecture
This clause deals with the complete ISO 17575-series, i.e. ISO 17575-1 to ISO 17575-3.
The definitions of ISO 17575 are relevant not only for interoperable EFC (as described below) but for all
possible autonomous EFC schemes.
ISO 17575 complies with the business architecture defined in ISO 17573:2010. 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 2).
As defined in ISO 17573:2010, the role of the toll charger includes the provision of the toll context data.
The ISO 17575 concept defines a one-to-one relationship between toll charger ID and toll context.
Therefore, it is justified to use the data type provider, as defined in ISO 14906:2011/Amd1:2015,
Annex A, to identify a toll context. If a toll charger operates more than one toll scheme, separate
identifiers shall be applied for in the central registry as defined in ISO 14906:2011/Amd1:2015.
Figure 2 — The role-based model underlying ISO 17575
Toll service providers issue OBE to the users of the road infrastructure. Toll service providers are
responsible for operating 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 toll service provider delivers charging data to several toll chargers, and, in general, each toll
charger receives charging data from more than one toll service provider. Interoperability management,
as shown in Figure 2, comprises all specifications and activities that define and maintain a set of rules
that govern the overall toll charging environment.
5.2 Technical architecture
The technical architecture shown in Figure 3 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, tariff
determination can be done with OBE tariff tables and processing, or with an off-board component.
6 © ISO 2016 – All rights reserved

Figure 3 — 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 the 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 3. Both extremes of architectural
choice have their merits and are one area where manufacturers compete with individual allocations of
functionality between on-board and central resources.
NOTE Especially for thin, but also for smart client, OBE manufacturers might devise a wide variety of
optimizations of the transfer of charge data between OBE and off-board components, where proprietary
algorithms are used for data reduction and data compression.
5.3 Location of the specification interface
In order to abstract from, and become independent of, these architectural implementation choices,
the primary scope of ISO 17575 is the data exchange between Front End and Back End (see the
corresponding vertical line in Figure 3). For every toll regime, the Back End shall send toll context data,
i.e. a description of the toll regime in terms of charge objects, charging rules and, if required, the tariff
scheme to the Front End, and shall receive usage data from the Front End.
It also has to be noted that the distribution of tasks and responsibilities between toll service provider
and toll charger will vary individually. Depending on the local legal situation, toll chargers will require
“thinner” or “thicker” data, and might or might not leave certain data processing tasks to toll service
providers. Hence, the data definitions in ISO 17575 may be useful on several interfaces.
ISO 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.
6 Procedural requirements
6.1 General
This part of ISO 17575 is intended to be used in autonomous toll systems set up according to the overall
architecture described in ISO 17573:2010.
It defines the format and semantics of charge reports and charge report responses, which are part of
the end-to-end information flow.
6.2 Toll collection process
On-board equipment (OBE) collects data on the road usage of an individual vehicle. These data are
aggregated and processed regarding their relevance for charging either in the OBE or in a proxy. The
combination of OBE and proxy is referred to as a Front End.
This part of ISO 17575 defines the data required for communicating charge relevant road usage data for
an individual vehicle from the Front End to the Back End. The Front End shall accumulate road usage data
into charge reports and send the charge reports to the Back End. The Back End shall confirm reception
of a charge report (ChargeReport) with a charge report response (ChargeReportResponse).
For supporting an uninterrupted chain of trust this part of ISO 17575 supports the authentication of
several data structures using the following data types:
— AuthenticatedChargeReport;
— AuthenticatedChargeReportResponse;
— AuthenticatedUsageStatement;
— AuthenticatedReloadAccount;
— AuthenticatedNewAccountLimit;
— AuthenticatedAddToAccount.
NOTE The use of and the combination of these data types with their unauthenticated counterparts
are left to agreements between the parties implementing this part of ISO 17575. For example, an
AuthenticatedChargeReport can be combined with an unauthenticated ChargeReportResponse, if this
is considered appropriate under specific circumstances.
6.3 Charge report
All data elements comprising the type ChargeReport are coded as optional (except for the
usageStatementList, which ultimately also contains only optional elements).
For every toll context, the Back End shall send context data to the Front End. Context data is a
description in terms of charge objects, charging rules and, if required, the tariff scheme. The definition
of the context data can be found in ISO 17575-3:2016.
Toll context data defines which data elements shall be present and which shall not. The Back End shall
communicate the toll context data defining the requested charge report contents to the Front End
before the OBE is expected to collect road usage data. Upon reception of toll context data the Front End
shall start to collect, process and accumulate road usage data into charge reports as requested. Toll
context data shall also define upon which events charge reports shall be communicated.
NOTE 1 The charge report content requirements defined by the toll context data allow setting the report
contents as required by the properties of the toll regime. These properties include the basic toll system
types such as
8 © ISO 2016 – All rights reserved

— road section charging (the charge relevant parameter is the sum of the road section lengths or tariff
used by the vehicle),
— area charging (the charge relevant parameter is either the distance driven inside the area or the time
stayed inside the area), and
— cordon charging (the charge relevant parameter is the event of crossing the cordon around an area).
NOTE 2 Depending on local needs, toll chargers may require more or less processed data to varying levels
of detail. Privacy considerations, enforcement approach and legal nature of the charge will also influence the
choices agreed between toll charger and toll service provider regarding the requested contents of charge reports.
Charge reports support
— reporting a list of charge objects that are declared as being used by the vehicle including associated
tariff modifiers; this report may or may not include the calculated fee or tax,
— reports of road usage sessions within a single set of tariff modifiers; this report may or may not
include the calculated fee or tax,
— report of contiguous sessions on a toll road or area where just the aggregated fee and the associated
reference time is reported,
— reports where only the total fee within a predefined report period is forwarded (in this case it is
anticipated that other means, outside the scope of this part of ISO 17575, are used to allow a certain
degree of validation of the charging process), and
— any combination of the reports listed above.
6.4 Charge report response
The Back End shall respond to every received charge report with a charge report response. A description
of which optional elements of the attribute ChargeReportResponse are present is not defined in
this part of ISO 17575.
NOTE The contents of the charge report response depend on the make and type of the Front End and on the
application software of the Front End and Back End as defined by the business requirements of the individual
toll service provider. This part of ISO 17575 only offers data elements for the response but does not impose
restrictions upon the implementation and business choices by requiring mandatory content.
7 Data elements
7.1 Overview of data elements
Data elements are grouped in logical groups for readability only.
The data group Reporting contains the main data elements of the charge report communication. These
elements are the top level, overarching data structures containing all data elements described in this
part of ISO 17575.
The data group General contains data elements and types that are not explicitly part of other groups.
The data group Security contains the data structures necessary for implementing authenticated
exchange of data using security mechanisms.
The data group Contract contains data elements and types related to road user contract information.
The data group Usage contains the information necessary to describe the usage of infrastructure
causing eligibility for fees. These data are necessary for calculating the charges and for setting up
correct bills and for settling disputes. The main data elements of this group present in the charge report
and charge report response are, respectively, usageStatementList and dataReceived.
The data group Account contains the elements necessary to ensure that the correct account (and road
user) is charged with the toll fees. The elements in the group account are used for managing road user
accounts in the Front End. These Front End accounts can contain the following types of data:
— credit: the account holds a value corresponding to a monetary amount;
— distance: the account holds a value representing a distance;
— time: the account holds a value representing a point in time;
— duration: the account holds a value representing time duration;
— event: the account holds a value representing a number of events.
The main data elements of this group present in the charge report and charge report response are,
respectively, accountStatus and accountUpdate.
NOTE The kind of event counted in the respective option of the account data type is left to the implementation.
The data group Versioning contains data elements for version control of elements on the OBE.
The data group Compliance Checking provides information exchanged in compliance checking
communication (CCC), as defined in ISO 12813:2015. Some of the data exchanged by CCC are already
covered by other data elements, but for complete information about the content of CCC the data in this
group are necessary.
7.2 Reporting
The two data types ChargeReport and ChargeReportResponse described in 7.2.1 and 7.2.2 cover
the complete charge report communication.

Introduction
0.1 Systèmes autonomes
L’ISO 17575 est une série de normes relatives à l’échange d’informations entre le système frontal et le
système central des applications de perception de télépéage (EFC, Electronic Fee Collection) reposant
sur un équipement embarqué (OBE, On-Board Equipment) autonome. Les systèmes EFC collectent
automatiquement les données de perception relatives à l’utilisation d’une infrastructure routière,
comprenant les péages d’autoroute, les redevances dans certaines zones urbaines, les péages relatifs
à une infrastructure particulière telles que ponts et tunnels, les imputations basées sur la distance
parcourue et les frais de stationnement.
Un OBE autonome fonctionne sans s’appuyer sur une infrastructure dédiée en bord de route en faisant
appel à des technologies à couverture étendue telles que les systèmes mondiaux de navigation par
satellite (GNSS) et les réseaux cellulaires (CN). Ces systèmes EFC ont diverses dénominations. Outre les
termes «systèmes autonomes» et «systèmes GNSS/CN», les termes «systèmes GPS/GSM» et «systèmes
de localisation par satellite» sont également utilisés.
Les systèmes autonomes utilisent la localisation par satellite, souvent combinée à des technologies de
détection supplémentaires telles que des gyroscopes, des odomètres et des accéléromètres, pour localiser
le véhicule et trouver sa position sur une carte contenant les objets géographiques soumis à redevance, tels
que des routes ou des zones soumises à péage. A partir des objets soumis à redevance, des caractéristiques
du véhicule, de l’heure de la journée et d’autres données pertinentes pour décrire l’utilisation du réseau
routier, le tarif et finalement la redevance d’utilisation du réseau routier sont déterminés.
Ces systèmes EFC autonomes présentent une réelle flexibilité permettant d’implémenter presque
tous les principes d’imputation existants et ne dépendent pas de l’infrastructure routière favorisant
l’interopérabilité de cette technologie dans les pays et les systèmes de perception. L’interopérabilité
ne peut être obtenue qu’avec des interfaces clairement définies, ce qui est l’objectif et la justification
de l’ISO 17575.
0.2 Parties de l’ISO 17575
Partie 1: Imputation, définit les attributs pour le transfert des données d’utilisation du système frontal
au système central. Le contenu des rapports de perception peut varier d’un régime de péage à l’autre; la
présente partie fournit en conséquence des attributs pour toutes les exigences, y compris des attributs
pour les données brutes de localisation, pour les objets géographiques de repérage cartographique et
pour les transactions de péage dont le prix est fixé. Un régime de péage comprend un ensemble de règles
d’imputation, y compris le réseau soumis à péage, les principes d’imputation, les véhicules assujettis au
péage et une définition du contenu exigé du rapport de perception.
Partie 2: Communications et connexions aux couches basses, définit les services de communication de base
pour le transfert des données sur la liaison aérienne de l’OBE ou entre le système frontal et le système
central. Les données définies dans la présente partie de l’ISO 17575-1 et de l’ISO 17575-3 peuvent être
échangées au moyen d’une pile de communication telle que définie dans l’ISO 17575-2, mais cet échange
n’est pas nécessaire.
Partie 3: Données du contexte, définit les données à utiliser pour la description de chaque système
de perception en termes d’objets géographiques soumis à redevance et de règles d’imputation et
d’établissement de rapports. Pour chaque système de percepteur de péage, les attributs définis dans la
norme ISO 17575-3 sont utilisés pour transférer des données vers le système frontal afin de lui indiquer
quelles données il doit collecter et utiliser pour générer des rapports.

Imputation
1 Domaine d’application
La présente partie de l’ISO 17575 définit le format et la sémantique pour l’échange de données entre
un système frontal (OBE plus proxy optionnel) et des systèmes centraux correspondants dans des
systèmes de péage autonomes. Elle définit les éléments de données utilisés pour générer des rapports
de perception contenant des informations sur l’utilisation du réseau routier par un véhicule pendant
des intervalles de temps donnés, envoyées du système frontal au système central. Elle définit également
les données qui peuvent être utilisées pour reconfigurer le processus de collecte permanente des
informations d’imputation pertinentes dans le système frontal. Son domaine d’application est
représenté à la Figure 1.
La constitution d’un rapport de perception dépend des données de configuration supposées être
présentes dans le système frontal. L’ensemble des rapports de perception peut être configuré pour
chaque système de péage individuel selon les besoins locaux. Les rapports de perception générés
conformément à la présente partie de l’ISO 17575 concordent avec les exigences dérivées du concept
architectural défini dans l’ISO 17573:2010.
Dans la présente partie de l’ISO 17575, les définitions comprennent
— les données des rapports, c’est-à-dire les données permettant de transférer des données d’utilisation
du réseau routier d’un système frontal à un système central, y compris une réponse du système
central au système frontal,
— les données de prise en charge des mécanismes de sécurité,
— les données contractuelles, c’est-à-dire les données permettant d’identifier les entités
contractuellement essentielles,
— les données d’utilisation du réseau routier, c’est-à-dire les données permettant de communiquer
l’utilisation qui est faite du réseau routier,
— les données de compte pour gérer un compte de paiement,
— les données de contrôle des versions,
— les données de contrôle de conformité, c’est-à-dire les données importées de l’ISO 12813:2015, qui
sont requises dans les communications de contrôle de conformité.

5 Considérations architecturales
5.1 Architecture commerciale
Le présent article traite de toute la série ISO 17575, c’est-à-dire de l’ISO 17575-1 à l’ISO 17575-3.
Les définitions de l’ISO 17575 s’appliquent non seulement aux systèmes EFC interopérables (décrits ci-
dessous), mais aussi à tous les systèmes EFC autonomes.
L’ISO 17575 est conforme à l’architecture commerciale définie dans l’ISO 17573:2010. Selon cette
architecture, le percepteur de péage est le fournisseur de l’infrastructure routière et donc le bénéficiaire
des redevances d’utilisation du réseau routier. Le percepteur de péage est l’acteur associé au rôle de
perception du péage (voir Figure 2).
Comme le définit l’ISO 17573:2010, le rôle du percepteur de péage prévoit la mise à disposition des
données de contexte de péage. Le concept de l’ISO 17575 définit une relation biunivoque entre l’ID du
percepteur de péage et le contexte de péage. En conséquence, l’utilisation du fournisseur du type de
données tel que défini dans l’ISO 14906:2011/Amd1:2015, Annexe A est justifiée pour identifier un
contexte de péage. Si un percepteur de péage applique plus d’un système de péage, des identifiants
séparés doivent être demandés dans le registre central, tel que défini dans l’ISO 14906:2011/Amd1:2015.

Figure 2 — Modèle basé sur les rôles servant à l’ISO 17575
Les prestataires de services fournissent un OBE aux utilisateurs de l’infrastructure routière. Les
prestataires de services sont responsables du fonctionnement de l’OBE qui enregistrera l’utilisation
du réseau routier dans tous les systèmes de perception du péage franchis par le véhicule, et de la
transmission des données de perception aux percepteurs de péage individuels. En général, chaque
prestataire de services transmet des données de perception à plusieurs percepteurs de péage, de même
que chaque percepteur de péage reçoit généralement des données de perception provenant de plusieurs

prestataires de services. La gestion de l’interopérabilité illustrée dans la Figure 2 inclut toutes les
spécifications et activités qui permettent de définir et de tenir à jour un ensemble de règles régissant
l’environnement de perception du péage.
5.2 Architecture technique
L’architecture technique de la Figure 3 ne dépend d’aucune réalisation pratique en particulier. Elle reflète
le fait que certaines fonctionnalités de traitement peuvent être allouées soit à l’OBE soit à un composant
associé non embarqué (proxy). Un exemple de fonctionnalité de traitement pouvant être réalisée à bord
ou à l’extérieur du véhicule est la corrélation d’images, dans laquelle les positions du véhicule en termes
de coordonnées mesurées par GNSS sont associées à des objets géographiques sur une carte qui réside
à bord ou à l’extérieur du véhicule. La détermination du tarif peut également être effectuée à l’aide de
tables tarifaires et d’un traitement dans l’OBE, ou à l’aide d’un composant non embarqué.

Figure 3 — Architecture technique et interfaces supposées
La fonctionnalité combinée de l’OBE et du proxy est appelée système frontal. L’implémentation d’un
système frontal dans lequel le traitement est essentiellement réalisé du côté OBE est connue en tant
que client intelligent (client lourd) ou «edge-heavy». Un système frontal dans lequel le traitement
est essentiellement réalisé à l’extérieur est appelé architecture de clients légers ou «edge-light». De
nombreuses implémentations entre les extrêmes «léger» et «lourd» sont possibles, comme indiqué
par la transition progressive des flèches à la Figure 3. Les deux extrêmes du choix architectural ont
chacun leurs avantages et sont l’un des moyens par lesquels les fabricants se font concurrence par des
allocations individuelles de fonctionnalité entre les ressources embarquées et centrales.
NOTE Dans le cas spécifique des clients légers, mais également des clients intelligents, les fabricants
d’OBE sont amenés à concevoir un large éventail d’optimisations pour le transfert des données d’imputation
entre l’OBE et les composants non embarqués, en utilisant des algorithmes propriétaires pour la réduction et la
compression des données.
5.3 Emplacement de l’interface de spécification
Pour se soustraire et devenir indépendant de ces choix d’implémentation architecturale, le principal
domaine d’application de l’ISO 17575 est l’échange de données entre le système frontal et le système
central (voir la ligne verticale correspondante à la Figure 3). Pour chaque régime de péage, le système
central doit envoyer des données de contexte de péage (ex: description du régime de péage en termes
d’objets d’imputation, de règles d’imputation et, si nécessaire, de régime tarifaire) au système frontal et
recevoir des données d’utilisation de celui-ci.
Il faut également noter que la répartition des tâches et des responsabilités entre le prestataire de
services de péage et le percepteur de péage variera individuellement. Selon la situation juridique locale,
les percepteurs de péage demanderont des données «plus légères» ou «plus lourdes» et pourraient
ou non laisser certaines tâches de traitement des données aux prestataires de services de péage. Par
conséquent, les définitions de données de l’ISO 17575 peuvent être utiles à plusieurs interfaces.
L’ISO 17575 prévoit également des services de communication de base indépendants des moyens qui
peuvent être utilisés pour la communication (filaire ou aérienne) entre le système frontal et le système
central, qui peuvent également être utilisés pour la liaison aérienne entre l’OBE et le serveur central de
communication.
6 Spécifications relatives aux procédures
6.1 Généralités
La présente partie de l’ISO 17575 est destinée à être utilisée dans des systèmes de péage autonomes
configurés conformément à l’architecture globale décrite dans l’ISO 17573:2010.
Elle définit le format et la sémantique des rapports de perception et des réponses aux rapports de
perception qui font partie du flux d’informations de bout en bout.
6.2 Perception du péage
Un équipement embarqué (OBE) collecte des données sur l’utilisation de la route par un véhicule individuel.
Ces données sont agrégées et traitées en ce qui concerne leur pertinence pour le péage, soit dans l’OBE soit
dans un proxy. La combinaison d’un OBE et d’un proxy est désignée en tant que système frontal.
La présente partie de l’ISO 17575 définit les données requises pour que le système frontal communique
au système central les données d’utilisation du réseau routier pertinentes pour le péage pour un
véhicule individuel. Le système frontal doit regrouper les données d’utilisation du réseau routier dans
des rapports de perception et transmettre ceux-ci au système central. Le système central doit confirmer
la réception d’un rapport de perception (ChargeReport) par une réponse au rapport de perception
(ChargeReportResponse).
Pour la prise en charge d’une chaîne de confiance ininterrompue, la présente partie de l’ISO 17575
reconnaît l’authentification de plusieurs structures de données au moyen des types de données suivants:
— AuthenticatedChargeReport;
— AuthenticatedChargeReportResponse;
8 © ISO 2016 – Tous droits réservés

— AuthenticatedUsageStatement;
— AuthenticatedReloadAccount;
— AuthenticatedNewAccountLimit;
— AuthenticatedAddToAccount.
NOTE L’utilisation et la combinaison de ces types de données avec leurs contreparties non authentifiées sont
laissées à l’appréciation des parties qui, en concertation, implémentent la présente partie de l’ISO 17575. Par
exemple, un type AuthenticatedChargeReport peut être combiné avec un type ChargeReportResponse
non authentifié, si cette démarche est considérée comme appropriée en les circonstances.
6.3 Rapport de perception
Tous les éléments de données constituant le type ChargeReport sont codés comme optionnels
(excepté l’élément de données usageStatementList, qui finalement ne contient lui aussi que des
éléments optionnels).
Pour chaque contexte de péage, le système central doit envoyer des données du contexte au système
frontal. Les données du contexte sont une description en termes d’objets d’imputation, de règles
d’imputation et, si nécessaire, de régime tarifaire. La définition des données du contexte peut être
trouvée dans l’ISO 17575-3:2016.
Les données de contexte de péage définissent les éléments de données devant être présents et ceux
ne devant pas être présents. Le système central doit transmettre au système frontal les données de
contexte de péage définissant le contenu du rapport de perception demandé avant que l’OBE ne collecte
les données d’utilisation du réseau routier. A réception des données de contexte de péage, le système
frontal doit commencer à collecter, traiter et accumuler les données d’utilisation du réseau routier dans
des rapports de perception conformes à la demande. Les données de contexte de péage doivent également
définir les événements pour lesquels des rapports de perception d’événement doivent être transmis.
NOTE 1 Les exigences relatives au contenu du rapport de perception définies par les données de contexte de
péage permettent de paramétrer le contenu de rapport comme requis par les propriétés du régime de péage. Ces
propriétés comprennent les types de système de péage de base tels que
— tarification de portion routière (le paramètre pertinent pour le péage est la somme des longueurs de section
de route ou le tarif utilisé par le véhicule),
— péage de zone (le paramètre pertinent pour le péage est soit la distance parcourue dans la zone soit le temps
passé dans la zone), et
— péage de cordon (le paramètre pertinent pour le péage est l’événement de franchissement du cordon
délimitant une zone).
NOTE 2 Selon les besoins locaux, les percepteurs de péage peuvent exiger des données plus ou moins
traitées à des niveaux de détail variables. Les considérations relatives au respect de la vie privée, la méthode de
contrôle-sanction et la nature juridique du péage auront également une incidence sur les choix convenus entre le
percepteur de péage et le prestataire de services
