European foreword

This document (prEN 15509:2020) has been prepared by Technical Committee CEN/TC 278 “Intelligent

transport systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.

This document will supersede EN 15509:2014, which has been technically revised. The main changes

compared to the previous editions are as follows:

— updated data definitions in order to reflect changes made to the underlying bases standards,

notably in EN ISO 14906 (i.e. EN ISO 14906:2018/A1:2020), whilst seeking to ensure backward

compatibility with previous editions of this document;

— updated terms, in order to take into account the harmonized terms between electronic fee

collection standards, as defined in ISO/TS 17573-2;

— deletion of the normative annex on “Security calculations”, which has been moved to EN ISO 14906;

— updated informative Annex H on the “Use of this document for the European electronic toll service”

[22]

(EETS), so as to reflect the recast of the EETS legislation (i.e. Directive (EU) 2019/520 and the

[21] [24]
corresponding Commission Delegated and Implementing Regulations .

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association.

Introduction

CEN/TC 278 has produced a set of standards that supports interoperable dedicated short-range

communication (DSRC)-based electronic fee collection (EFC) systems (e.g. EN ISO 14906, a “toolbox” for

definition of EFC-DSRC transactions). However, these standards are necessary but not sufficient to

ensure technical interoperability between EFC-DSRC-systems.

This document defines an Interoperable Application Profile (IAP) to support EFC-DSRC transactions, a

coherent set of requirements. The main objective is to support technical interoperability between EFC-

systems within the scope of this document (as defined in Clause 1 below). A basic description of the

EFC-service and an EFC System can be found in EN ISO 17573-1.

This document 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, nor does it define other parts of the EFC-system, other services, other technologies and

non-technical elements of interoperability.

The elaboration of this document is based on the experiences from a considerable number of

implementations and projects throughout Europe. This document 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

[20]

Directive (2004/52/EC ) also calls for the definition of an interoperable EFC-service. The first edition

of this document was referenced as a mandatory element in the service definition of the EETS, in the EC

[21]
decision 2009/750/EC .

The revision of the EETS legislation (recast in EU legal parlance) resulted in the adoption of Directive

[22]

2019/520/EC on the interoperability of electronic road tolling systems and facilitating cross-border

exchange of information on the failure to pay road fees in the Union, which refers to the second edition

of this document (EN 15509:2014) as a mandatory element for the EETS. Further technical and

procedural characteristics of the EETS were laid down in the associated Commission Delegated

[24] [24]
Regulation (EU) 2020/203 and Commission Implementing Regulation (EU) 2020/204 .

Although there are standards and specifications, there are specific needs that motivate this document:

— Definition of the necessary and sufficient EFC-DSRC requirements to underpin technical

interoperability;
— 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);

— The provisions laid down in Directive 2019/520/EC and the associated Commission Regulations;

— 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.

---------------------- Page: 7 ----------------------
oSIST prEN 15509:2021
prEN 15509:2020 (E)
The principles of the ISP-concept can be summarized as follows:
— An ISP makes references only to base standards or other ISPs;

— The profile restricts 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 does not copy content of the base standards (in order to avoid consistency problems with

the base standards);

— The profile does 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 document. Toll Chargers, Toll Service Providers and Manufacturers may use

this IAP as a basis for interoperable use of their equipment, without having to interfere with or

otherwise affect any EFC-system used locally.

The general requirements of the IAP 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 document 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 the document.

This document 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 prEN 15509

(this document). 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 of revision to accommodate the changes introduced in this

document.

1 Scope
The scope for this document is limited to:
— payment method: Central account based on EFC-DSRC;

— physical systems: on-board unit (OBU), roadside equipment (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.
It is outside the scope of this document to define:

— contractual and procedural interoperability requirements (including issues related to a

memorandum of understanding, MoU);
— conformance procedures and test specifications;

— 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 document

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. compliance check communication and

localization augmentation communication, which are 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).

NOTE Some of the issues that are outside the scope of this document are subject of separate standards

prepared by CEN/TC 278, ISO/TC 204 and ETSI ERM.
