EN 15509:2014 (E) 5 Foreword This document (EN 15509:2014) has been prepared by Technical Committee CEN/TC 278 “Intelligent transport systems”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2015 and conflicting national standards shall be withdrawn at the latest by March 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15509:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This second edition of EN 15509 incorporates the following main modifications compared to the previous one: — amendment of terms, in order to reflect harmonization of terms across electronic fee collection (EFC) standards; — addition of a new clause (i.e. Clause 5) on conformance; — amendment of the definition of vehicle licence plate number (size constraints and clarification that only Latin alphabet coding is supported) — revision of the informative annex on security considerations (i.e. Annex F), and reference to CEN/TS 16439 on Electronic fee collection – Security framework; — addition of a new informative annex (i.e. Annex I) on how to use this standard for the European electronic toll service; — deletion of informative Annex H, part of the first edition, on Vehicle classification data, as it was deemed obsolete in view of EN ISO 14906:2011; — deletion of informative Annex I, part of the first edition, on Using this European Standard for other DSRC-based transactions, as it was deemed obsolete in view of CEN ISO/TS 12813 and CEN ISO/TS 13141;
— amendments to reflect changes to the underlying base standards, with emphasis on backward compatibility with the first edition of this standard. For the revision of this European Standard, the following principles have been used: — take into account the evolution of some of the underlying standards and technical specifications, i.e. EN ISO 14906:2011, CEN/TS 16439, ISO/IEC 9797-1; — maintain compatibility with the previous edition of this European Standard. This European Standard defines an Application Profile based on a set of base standards according to the concept of "International Standardised Profiles (ISP)" as defined in ISO/IEC/TR 10000-1. The objective is to support technical interoperability between EFC DSRC-based systems in Europe. The principles of Application Profiling and relations to underlying base standards are defined in the Introduction. SIST EN 15509:2014



EN 15509:2014 (E) 6 According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 15509:2014



EN 15509:2014 (E) 7 Introduction CEN/TC 278 has produced a set of standards that supports interoperable electronic fee collection (EFC) dedicated short-range communication (DSRC)-based systems (e.g. EN ISO 14906, a “toolbox” for defining EFC-application transactions). However, these standards are necessary but not sufficient to ensure technical interoperability between DSRC-EFC-systems. This European Standard provides for a coherent set of requirements of the EFC-application and that is intended to serve as a common technical platform for EFC-interoperability. This European Standard defines an Interoperable Application Profile for DSRC-EFC transactions. The main objective is to support technical interoperability between EFC-systems within the scope of this European Standard (as defined in Clause 1 below). A basic description of the EFC-service and an EFC System can be found in ISO 17573. This European Standard only defines a basic level of technical interoperability for EFC equipment, i.e. on-board unit (OBU) and roadside equipment (RSE) using DSRC. It does not provide a full solution for interoperability, and it does not define other parts of the EFC-system, other services, other technologies and non-technical elements of interoperability. The elaboration of this European Standard is based on the experiences from a vast number of implementations and projects throughout Europe. The standard makes use of the results from European projects such as CARDME, PISTA and CESARE, as they represent the fruit of European EFC harmonization and have been used as the basis for several national implementations. The development of a common European Electronic Toll Service (EETS) as a part of the European Directive (2004/52/EC) also calls for the definition of an interoperable EFC-service. This European Standard provides for effective support for the work on the definition of EETS. After publication of EN 15509:2007 an EC-decision (2009/750/EC) on the EETS was adopted, that notes the first edition of this standard (EN 15509:2007) as a mandatory technical reference for the EETS. This has been fully maintained in this second edition of EN 15509. Although there already are numerous existing base standards and specifications, there are specific needs that motivate this Interoperable Application Profile standard: — Definition of the necessary and sufficient EFC-DSRC requirements to support technical interoperability; — Provision of a crucial part of the EETS and hence support for the European Directive (2004/52/EC), the European Commission Decision (2009/750/EC of October 2009) on the definition of the European Electronic Toll Service and its technical elements complemented by the Guide for the application of the directive on the interoperability of electronic road toll systems; — CARDME/PISTA/CESARE dialects are used in many countries but they need to converge, as the present situation is not cost effective; — Needed additional DSRC-requirements are made; — Choice of data elements including vehicle data; — Extended definition of the use of some data elements, including semantics and coding; — Clear choices for security implementation; — It facilitates a complementing test specification (with clear relations between the conformance requirements and evaluation tests); — Good support for procurements. SIST EN 15509:2014



EN 15509:2014 (E) 8 The Application Profile is described using the concept of "International Standardised Profiles (ISP)" as defined in ISO/IEC/TR 10000-1. The ISP-concept is specifically suited for defining interoperability specifications where a set of base standards can be used in different ways. This is exactly the case in EFC, where a set of base standards allows for different choices that are not interoperable. The principles of the ISP-concept can be summarized as follows: — An ISP shall make references only to base standards or other ISPs; — The profile shall restrict the choice of base standard options to the extent necessary to maximize the probability of interoperability (e.g. chosen classes, conforming subsets, options and parameter values of base standards); — The ISP shall not copy content of the base standards (in order to avoid consistency problems with the base standards); — The profile shall not specify any requirements that would contradict or cause non-conformance to the base standards; — The profile may contain conformance requirements that are more specific and limited in scope than those of the base standards; — Conformance to a profile implies by definition conformance to a set of base standards, whereas conformance to that set of base standards does not necessarily imply conformance to the profile. The use of the Application Profiling concept also provides for a flexible framework towards adoption, migration and use of this European Standard. Toll Chargers, Toll Service Providers and Manufacturers may use this Application Profile as a basis for interoperable use of their equipment, without having to disturb or otherwise affect any EFC-system used locally. The general requirements of the Interoperable Application Profile are set out in Clause 5, whilst the specific conformance requirements are given in Clause 6. To facilitate easy referencing, testing and look-up, these specific requirements are divided into two parts; On-Board Unit (OBU) requirements and Roadside Equipment (RSE) requirements. In addition this European Standard also includes various annexes that provide further detailed specifications as well as background, motivation and examples for the conformance requirements. The intention is that these enhance readability and understanding of this European Standard. The base standard EN ISO 14906:2011 has been the subject of a revision. The revision of EN 15509 takes into account the revision introduced in this base standard. This European Standard is complemented by a set of standards defining Conformity Evaluation of the Conformance Requirements. EN 15876 defines how to evaluate on-board and roadside equipment for conformity to EN 15509 (this European Standard). EN 15876 consists of the following parts, under the general title "Electronic fee collection — Evaluation of on-board and roadside equipment for conformity to EN 15509": — Part 1: Test suite structure and test purposes; — Part 2: Abstract test suite. NOTE
EN 15786-1 and EN 15786-2 will be subject to revision to accommodate the changes introduced in this second edition of EN 15509. SIST EN 15509:2014



EN 15509:2014 (E) 9 1 Scope The scope for this European Standard is limited to: — payment method: Central account based on EFC-DSRC; — physical systems: OBU, RSE and the DSRC interface between them (all functions and information flows related to these parts); — DSRC-link requirements; — EFC transactions over the DSRC interface; — data elements to be used by OBU and RSE used in EFC-DSRC transactions; — security mechanisms for OBU and RSE used in EFC-DSRC transactions. The scope of this European Standard is illustrated in Figure 1.
Figure 1 — Scope for this European Standard (within the box delimited with a dotted line) It is outside the scope of this European Standard to define: — contractual and procedural interoperability requirements (including issues related to a Memorandum of Understanding, MoU); — conformance procedures and test specification (this is provided in a separate set of standards); SIST EN 15509:2014



EN 15509:2014 (E) 10 — setting-up of operating organizations (e.g. toll charger, toll service provider, trusted third party, etc.); — legal issues; — other payment methods in DSRC-based EFC (e.g. on-board accounts using integrated circuit cards); — other basic technologies (e.g. GNSS/CN or video registration based EFC). However, this European Standard may be used for defining the DSRC-EFC parts for the use in applications that implement a mix of different technologies; — non-EFC transactions over the DSRC interface (e.g. CCC and LAC communication, which is defined in other standards); — other interfaces or functions in EFC-systems than those specified above (i.e. information flows and data exchange between operators or personalization, initialization and customization of the OBU). Some of these issues are subject to separate standards prepared by CEN/TC 278, ISO/TC 204 or ETSI ERM. Figure 2 shows the scope of this European Standard from a DSRC-stack perspective.

Introduction
CEN/TC 278(/WG 1) has produced a set of standards that supports interoperable electronic fee collection
(EFC) dedicated short-range communication (DSRC)-based systems (e.g. EN ISO 14906, a “toolbox” for
defining EFC-application transactions). However, these standards are necessary but not sufficient to ensure
technical interoperability. This European Standard provides for a coherent set of requirements of the EFC-
application that may serve as a common technical platform for EFC-interoperability.
This European Standard defines an Interoperable Application Profile for DSRC-EFC transactions. The main
objective is to support technical interoperability between EFC-systems within the scope of this European
Standard (as defined in Clause 1 below). A basic description of the EFC-service and an EFC System can be
found in ISO 17573.
This European Standard only defines a basic level of technical interoperability for EFC equipment, i.e. on-
board unit (OBU) and roadside equipment (RSE) using DSRC. It does not provide a full solution for
interoperability, and it does not define other parts of the EFC-system, other services, other technologies and
non-technical elements of interoperability.
The first elaboration of this European Standard was based on the experiences from a vast number of
implementations and projects throughout Europe. This European Standard makes use of the results from
European projects such as CARDME, PISTA and CESARE, as they represent the fruit of European EFC
harmonisation and have been used as the basis for several national implementations. The development of a
common European Electronic Toll Service (EETS) as a part of the European EFC Directive (2004/52/EC) also
calls for the definition of an interoperable EFC-service. This European Standard provides for effective support
for the work on the definition of EETS.
For the revision of this European Standard, the following principles have been followed:
 take into the evolution of the base standards;
 keep compatibility with the previous version of this European Standard.
Although there already are numerous existing base standards and specifications, there are specific needs that
motivate this Interoperable Application Profile standard.
 Definition of the necessary and sufficient EFC-DSRC requirements to support technical interoperability.
 Provision of a crucial part of the EETS and hence support for the EFC Directive (2004/52/EC), the
Commission Decision of 6 October 2009 on the definition of the European Electronic Toll Service and its
technical elements complemented by the Guide for the application of the directive on the interoperability
of electronic road toll systems
 CARDME/PISTA/CESARE dialects are used in many countries but they need to converge, as the present
situation is not cost effective.
 Needed additional DSRC-requirements are made.

 It facilitates a complementing test specification (with clear relations between the conformance
requirements and evaluation tests).
 Good support for procurements.
The Application Profile is described using the concept of "International Standardised Profiles (ISP)" as defined
in ISO/IEC TR 10000-1. The ISP-concept is specifically suited for defining interoperability specifications where
a set of base standards can be used in different ways. This is exactly the case in EFC, where a set of base
standards allows for different choices that are not interoperable.
The principles of the ISP-concept can be summarised as follows.
 An ISP shall make references only to base standards or other ISPs.
 The profile shall restrict the choice of base standard options to the extent necessary to maximise the
probability of interoperability (e.g. chosen classes, conforming subsets, options and parameter values of
base standards).
 The ISP shall not copy content of the base standards (in order to void consistency problems with the base
standards).
 The profile shall not specify any requirements that would contradict or cause non-conformance to the
base standards.
 The profile may contain conformance requirements that are more specific and limited in scope than those
of the base standards.
 Conformance to a profile implies by definition conformance to a set of base standards, whereas
conformance to that set of base standards does not necessarily imply conformance to the profile.
The use of the Application Profiling concept also provides for a flexible framework towards adoption, migration
and use of this European Standard. Toll Chargers, Toll Service Providers and Manufacturers may use this
Application Profile as a basis for interoperable use of their equipment, without having to disturb or otherwise
affect any EFC-system used locally.
The Interoperable Application Profile is defined in terms of conformance requirements as given in Clause 5.
To facilitate easy referencing, testing and look-up, these requirements are divided into two parts; On-Board
Unit (OBU) requirements (5.1) and Roadside Equipment (RSE) requirements (5.2).
In addition this European Standard also includes various annexes that provide further detailed specifications
as well as background, motivation and examples for the conformance requirements. The intention is that
these enhance readability and understanding of this European Standard.
The base standard EN ISO 14906:2011 has been the subject of a revision. The revision of EN 15509 takes
into account this fact.
This European Standard is complemented by a set of standards defining Conformity Evaluation of the
Conformance Requirements.
EN 15876 defined how to evaluate on-board and roadside equipment for conformity to EN 15509 (this
European Standard). EN 15876 consists of the following parts, under the general title "Electronic fee
collection — Evaluation of on-board and roadside equipment for conformity to EN 15509":
 Part 1: Test suite structure and test purposes;
 Part 2: Abstract test suite.

1 Scope
The scope for this European Standard is limited to
 payment method: Central account based on EFC-DSRC,
 physical systems: OBU, RSE and the DSRC interface between them (all functions and information flows
related to these parts),
 DSRC-link requirements,
 EFC transactions over the DSRC interface,
 data elements to be used by OBU and RSE used in EFC-DSRC transactions,
 security mechanisms for OBU and RSE used in EFC-DSRC transactions.
The scope of this European Standard is illustrated in Figure 1.

Figure 1 — Scope for this European Standard (within the box delimited with a dotted line)
It is outside the scope of this European Standard to define
 contractual and procedural interoperability requirements (including issues related to a Memorandum of
Understanding, MoU),
 conformance procedures and test specification (this is provided in a separate set of standards),
 setting-up of operating organisations (e.g. clearing operator, issuing, trusted third party etc.),
 legal issues,
 other payment methods in DSRC-based EFC (e.g. on-board accounts using integrated circuit cards),

 other basic technologies (e.g. GNSS/CN or video registration based EFC). However, this European
Standard may be used for defining the DSRC-EFC parts for the use in applications that implement a mix
of different technologies.
 other interfaces or functions in EFC-systems than those specified above (i.e. information flows and data
exchange between operators or personalisation, initialisation and customisation of the OBU).
Some of these issues are subject to separate standards prepared by CEN/TC 278, ISO/TC 204 or ETSI ERM.
Figure 2 shows the scope of this European Standard from a DSRC-stack perspective.

Figure 2 — Relationship between this European Standard and DSRC-stack elements
This European Standard defines an Application Profile based on the ISP-concept. The base standards that
this Application Profile is based upon are
 EN ISO 14906 on EFC application interface definition for DSRC (this implies indirect references to
EN ISO 14816 on Numbering and data structures),
 EN 12834: on DSRC application layer (L7),
 EN 13372 on DSRC profiles (this implies indirect references to the DSRC L1, L2 and L7 standards:
EN 12253, EN 12795 and EN 12834).
