Electronic fee collection - Localisation augmentation communication for autonomous systems (ISO 13141:2015)

ISO 13141:2015 establishes requirements for short-range communication for the purposes of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization augmentation serves to inform on-board equipment (OBE) about geographical location and the identification of a charge object. This International Standard specifies the provision of location and heading information and security means to protect from the manipulation of the OBE with false roadside equipment (RSE).
The localization augmentation communication takes place between an OBE in a vehicle and fixed roadside equipment. This International Standard is applicable to OBE in an autonomous mode of operation.
ISO 13141:2015 defines attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are defined on the level of Application Data Units (ADUs, see Figure 1).

Perception de télépéage - Communications d'augmentation de localisations pour systèmes autonomes (ISO 13141:2015)

ISO 13141:2015 définit les exigences pour une communication à courte portée en vue de mettre en place l'augmentation de localisations dans les systèmes de perception du télépéage (EFC) autonomes. L'augmentation de localisations sert à informer les équipements embarqués (OBE) de leur position géographique et à l'identification d'un objet de facturation. La présente Norme internationale spécifie la mise à disposition des informations de localisation et de direction, et constitue une protection contre la manipulation des équipements embarqués par des équipements routiers (RSE) frauduleux.
Les communications d'augmentation de localisations s'effectuent entre l'équipement embarqué sur un véhicule et un équipement routier fixe. La présente Norme internationale s'applique aux équipements embarqués autonomes.
Elle définit des attributs et des fonctions pour l'augmentation de localisations au moyen des services de communication DSRC fournis par la couche DSRC 7; elle met ces attributs et ces fonctions LAC à la disposition des applications LAC au niveau des équipements routiers et des équipements embarqués. Les attributs et les fonctions sont définis au niveau des unités de données d'application (ADU, Application Data Unit; voir Figure 1).

Elektronsko pobiranje pristojbin - Lokalizacija povečane gostote komunikacije za avtonomne sisteme (ISO 13141:2015)

Ta mednarodni standard vzpostavlja zahteve za komunikacijo kratkega dosega za namene razširjene lokalizacije v avtonomnih sistemih za elektronsko pobiranje pristojbin. Na podlagi razširjene lokalizacije lahko oprema, vgrajena v vozilo, prejema podatke o geografski lokaciji in identiteti objekta zaračunavanja. Ta mednarodni standard določa način posredovanja podatkov o lokaciji in poti objekta ter varnostne ukrepe za preprečevanje vpliva na opremo, vgrajeno v vozilo, z napačno obcestno opremo.
Med opremo, vgrajeno v vozilo, in nameščeno obcestno opremo steče komunikacija za razširjeno lokalizacijo. Ta mednarodni standard se uporablja za opremo, vgrajeno v vozilo, v avtonomnem načinu delovanja. Ta mednarodni standard določa atribute in funkcije za namene razširjene lokalizacije na podlagi storitev namenske komunikacije kratkega dosega (7. raven) ter omogoča uporabo teh atributov in funkcij za komunikacijo za razširjeno lokalizacijo v obcestni opremi in opremi, vgrajeni v vozilo. Atributi in funkcije so določeni na ravni aplikacijskih podatkovnih enot (glej sliko 1).
Kot je prikazano na sliki 1, se ta mednarodni standard uporablja za:
– definicijo aplikacijskega vmesnika med opremo, vgrajeno v vozilo, in obcestno opremo;
– vmesnik za aplikacijsko raven namenske komunikacije kratkega dosega, kot je določeno v standardih ISO 15628 in EN 12834;
– uporabo sklada namenske komunikacije kratkega dosega.
Komunikacija za razširjeno lokalizacijo je primerna za nabor medijev za komunikacijo kratkega dosega. Ta mednarodni standard podaja posebne opredelitve za sklad namenske komunikacije kratkega dosega CEN, kot je določeno v standardu
EN 15509, dodatki C, D in E pa opredeljujejo uporabo italijanskega sistema namenske komunikacije kratkega dosega, kot je določeno v standardih ETSI/ES 200 674-1, ISO CALM IR in ARIB DSRC.
Ta mednarodni standard vključuje proformo formalne izjave o skladnosti izvedbe protokola (PICS) v dodatku B in informativne primere transakcij v dodatku F. Informativni dodatek G izpostavlja, kako uporabljati ta mednarodni standard za evropske sisteme elektronskega cestninjenja (kot je opredeljeno v
Odločbi Komisije 2009/750/ES).
Področje uporabe tega mednarodnega standarda ne zajema specifikacij preskusov.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

On-board equipment (OBE) that uses satellite-based positioning technology to collect data required for

charging for the use of roads operates in a so-called autonomous way (i.e. generally without relying

on dedicated roadside infrastructure). However, these autonomous systems can, in particular places,

need some roadside infrastructure support for proper identification of charge objects. Such assistance

might be required at places where satellite-based localization accuracy or availability is insufficient or

at places where the OBE is directly informed about the identity of the relevant charge object.

In an interoperable environment, it is essential that this localization information be available in a

standardized way. This International Standard defines requirements for localization augmentation by

dedicated short-range communication (DSRC) between roadside equipment and on-board equipment.

This International Standard makes no assumptions about the operator of the roadside equipment

(RSE), in terms of his role according to ISO 17573, i.e. whether the RSE is operated by an entity in the

service provision role or in the toll charging role.

This International Standard has been prepared considering the following requirements:

— the localization augmentation communication (LAC) serves to transmit localization information to

passing OBE without identifying individual OBE;

— the localization information contains both geographical location independent of charging context,

and context-dependent identification of charge objects;

— a single roadside installation is able to provide localization augmentation for several overlapping

EFC contexts;

— this International Standard is based on the EFC architecture specified in ISO 17573;

— the communication applies to all OBE architectures;

— this International Standard is applicable to various DSRC media, especially the CEN DSRC stack;

— the communication supports security services for data origin authentication, integrity and non-

repudiation.

This International Standard defines an attribute, LACData, which is communicated from the RSE to

the OBE by means of an acknowledged writing service, which is implemented through the SET service

of DSRC Layer 7 (ISO 15628 and EN 12834). The LAC application is defined as a self-contained DSRC

application with its own application identifier (AID). Regarding the DSRC communications stack, this

International Standard gives definitions for the CEN DSRC stack, as used in EN 15509 and Annexes C,

D and E demonstrate, respectively, the use of ISO CALM IR, the use of Italian DSRC as specified in

ETSI/ES 200674-1 and ARIB DSRC.

All data relevant for the LAC application have been put into the attribute LACData, in order to create

a single standard communications content transmitted by LAC RSE, and always signed as a whole.

LACData can transport both geographic coordinates (latitude, longitude and altitude) and the

identification of a specific charge object. All elements of LACData are mandatory, but Null values are

defined to allow LAC installations to transmit only a selection of all defined data elements.

Access credentials are mandatory for writing LACData in order to protect OBE from non-authentic

RSE. LACData are critical for charge determination and for providing evidence. For these purposes, the

authenticators which are defined can be used to provide for data origin authentication, data integrity and

non-repudiation for LACData. There are two separate authenticator fields defined to allow for separate

authentication and non-repudiation, if required by the institutional arrangements of a toll system.

This International Standard is “minimalist” in the sense that it covers what is required by operational

systems and systems planned in the foreseeable future.

Electronic fee collection — Localisation augmentation
communication for autonomous systems
1 Scope

This International Standard establishes requirements for short-range communication for the purposes

of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization

augmentation serves to inform on-board equipment (OBE) about geographical location and the

identification of a charge object. This International Standard specifies the provision of location and

heading information and security means to protect from the manipulation of the OBE with false

roadside equipment (RSE).

The localization augmentation communication takes place between an OBE in a vehicle and fixed roadside

equipment. This International Standard is applicable to OBE in an autonomous mode of operation.

This International Standard defines attributes and functions for the purpose of localization

augmentation, by making use of the dedicated short-range communications (DSRC) communication

services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC

applications at the RSE and the OBE. Attributes and functions are defined on the level of Application

Data Units (ADUs, see Figure 1).
As depicted in Figure 1, this International Standard is applicable to:
— the application interface definition between OBE and RSE;

— the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834;

— the use of the DSRC stack.

The localization augmentation communication is suitable for a range of short-range communication

media. This International Standard gives specific definitions regarding the CEN DSRC stack as specified

in EN 15509, and Annexes C, D and E give the use of the Italian DSRC as specified in ETSI/ES 200 674-1,

ISO CALM IR, and ARIB DSRC.

This International Standard contains a protocol implementation conformance statement (PICS)

proforma in Annex B and informative transaction examples in Annex F. The informative Annex G

highlights how to use this International Standard for the European electronic toll service (as defined in

Commission Decision 2009/750/EC).
Test specifications are not within the scope of this International Standard.
