Electronic fee collection — Compliance check communication for autonomous systems (ISO/DIS 12813:2022)

This document defines requirements for short-range communication for the purposes of compliance checking in autonomous electronic fee collecting systems. Compliance checking communication (CCC) takes place between a road vehicle's on-board equipment (OBE) and an interrogator (roadside mounted equipment, mobile device or hand-held unit), and serves to establish whether the data that are delivered by the OBE correctly reflect the road usage of the corresponding vehicle according to the rules of the pertinent toll regime.
The operator of the compliance checking interrogator is assumed to be part of the toll charging role as defined in ISO 17573-1. The CCC permits identification of the OBE, vehicle and contract, and verification of whether the driver has fulfilled his obligations and the checking status and performance of the OBE. The CCC reads, but does not write, OBE data.
This document is applicable to OBE in an autonomous mode of operation; it is not applicable to compliance checking in dedicated short-range communication (DSRC)-based charging systems.
It defines data syntax and semantics, but not a communication sequence. All the attributes defined herein are required in any OBE claimed to be compliant with this document, even if some values are set to "not defined" in cases where certain functionality is not present in an OBE. The interrogator is free to choose which attributes are read in the data retrieval phase, as well as the sequence in which they are read. In order to achieve compatibility with existing systems, the communication makes use of the attributes defined in ISO 14906 wherever useful.
The CCC is suitable for a range of short-range communication media. Specific definitions are given for the CEN-DSRC as specified in EN 15509, as well as for the use of ISO CALM IR, the Italian DSRC as specified in ETSI ES 200 674-1, ARIB DSRC and WAVE DSRC as alternatives to the CEN-DSRC. The attributes and functions defined are for compliance checking by means of the DSRC communication services provided by DSRC application layer, with the CCC attributes and functions made available to the CCC applications at the roadside equipment (RSE) and OBE. The attributes and functions are defined on the level of application data units (ADU).
The definition of the CCC includes:
— the application interface between OBE and RSE (as depicted in Figure 2);
— use of the generic DSRC application layer as specified in ISO 15628 and EN 12834;
— CCC data type specifications given in Annex A;
— a protocol implementation conformance statement (PICS) proforma is given in Annex B;
— use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described in Annex C, Annex D, Annex E and Annex F;
— security services for mutual authentication of the communication partners and for signing of data (see Annex H);
— an example CCC transaction is presented in Annex G;
— the informative Annex I highlights how to use this document for the European electronic toll service (as defined in Commission Decision 2009/750/EC).
Test specifications are not within the scope of this document.

Elektronische Gebührenerhebung - Kommunikation zur Übereinstimmungsprüfung für autonome Systeme (ISO/DIS 12813:2022)

Perception de télépéage - Communication de contrôle de conformité pour systèmes autonomes (ISO/DIS 12813:2022)

Le présent document définit les exigences relatives aux communications à courte portée aux fins de contrôle de conformité dans les systèmes de perception électronique de télépéage autonomes. La communication de contrôle de conformité (CCC, Compliance Checking Communication) survient entre l'équipement embarqué d'un véhicule routier et un interrogateur externe (équipement en bord de route, appareil mobile ou dispositif portable) et permet de déterminer si les données fournies par l'équipement embarqué reflètent correctement l'usage du réseau routier par le véhicule correspondant selon les règles du régime de péage applicable.
L'exploitant de l'interrogateur de contrôle de conformité est supposé participer au rôle Perception du péage défini dans l'ISO 17573-1. L'application CCC permet d'identifier l'équipement embarqué, le véhicule et le contrat, de vérifier que le conducteur a bien rempli ses obligations et de déterminer l'état de fonctionnement et la performance de l'équipement embarqué. L'application CCC lit, mais n'écrit pas les données de l'équipement embarqué.
Le présent document s'applique aux équipements embarqués autonomes; il ne s'applique pas au contrôle de conformité dans les systèmes de taxation reposant sur des communications dédiées à courte portée (DSRC).
Il définit la syntaxe et la sémantique des données, mais ne définit pas de séquence de communication. Tous les attributs qui y sont définis sont exigés dans tout équipement embarqué revendiqué conforme au présent document, même si certaines valeurs sont définies comme étant «non définies» dans les cas où certaines fonctionnalités ne sont pas présentes dans un équipement embarqué donné. L'interrogateur est libre de choisir quels attributs sont lus, ainsi que l'ordre dans lequel ils sont lus. Afin de permettre la compatibilité avec les systèmes existants, la communication utilise les attributs définis dans l'ISO 14906 chaque fois que cela est utile.
L'application CCC est adaptée à toute une variété de supports de communication à courte portée. Des définitions spécifiques sont données pour la pile de communication CEN-DSRC spécifiée dans l'EN 15509, ainsi que pour l'utilisation des piles ISO CALM IR, UNI DSRC (ETSI ES 200 674-1) et ARIB DSRC comme alternatives à CEN-DSRC. Les attributs et fonctions définis sont destinés au contrôle de conformité via les services de communication DSRC fournis par la couche d'application DSRC, à l'aide des attributs et fonctions CCC mis à la disposition des applications CCC sur l'équipement en bord de route (RSE, Road-Side Equipment) et l'équipement embarqué. Les attributs et fonctions sont définis au niveau des unités de données d'application (ADU, Application Data Unit).
La définition de la communication CCC inclut:
— l'interface d'application entre l'équipement embarqué (OBE) et l'équipement en bord de route (RSE) comme décrit en Figure 2;
— l'utilisation de la couche d'application DSRC générique spécifiée dans l'ISO 15628 et l'EN 12834;
— les spécifications de types de données CCC données à l'Annexe A;
— un formulaire de déclaration de conformité d'une mise en œuvre de protocole (PICS, Protocol Implementation Conformance Statement) est fourni à l'Annexe B;
— l'utilisation de la pile CEN-DSRC selon l'EN 15509 ou d'autres piles de communication DSRC équivalentes comme décrit à l'Annexe C, l'Annexe D, l'Annexe E et l'Annexe F;
— des services de sécurité dans le cadre de l'authentification mutuelle des partenaires de communication et de la sig

Introduction

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

charging for the use of roads operates in an autonomous way (i.e. without relying on dedicated roadside

infrastructure). The OBE will record the amount of road usage in all toll charging systems it passes

through.

This document defines requirements for dedicated short-range communication (DSRC) between OBE

and an interrogator for the purpose of checking compliance of road use with a local toll regime. It

assumes an electronic fee collection (EFC) services architecture according to ISO 17573-1. See Figure 1.

Figure 1 — Compliance check communication in EFC architecture according to ISO 17573-1

Toll chargers have the need to check whether the road is used in compliance with the rules in the local

toll regime. One way of checking compliance is to observe a passing vehicle and to interrogate the OBE.

This interrogation happens under control of an entity responsible for toll charging (see Figure 1),

accomplished via short-range communication between an interrogator at roadside or in another vehicle

(operated by a competent enforcement agency) and the OBE. In an interoperable environment, it is

essential that this interrogation communication be standardized such that every operator of compliance

checking equipment can check all passing OBE. For that purpose, this document defines attributes

required on all OBE for reading by an interrogator.
This document has been prepared to fulfil the following statements:

a) Collected evidence can be used as court proof. Data is indisputable and secured such that the

operator of the compliance checking interrogator can prove the integrity and authenticity of the

data in case of dispute.

b) The data required for compliance checking is read only, since the operator of the interrogator does

not interfere with the working of the OBE.

c) All attributes, standardized at the time of personalisation of the OBE, are present in the OBE such

that an operator of an interrogator essentially can read the same data from all OBE independent of

type and make. In case an attribute does not make sense in a certain OBE implementation, a value

oSIST prEN ISO 12813:2022
ISO/DIS 12813:2022 (E)

assignment for “not applicable” or “not defined” is provided in each case. An OBE compliant to the

first edition will not answer with such a response for new attributes introduced in the current

edition of this document.

d) The attributes, derived from the individual toll regime, are of general importance for all toll system

types (motorway tolling, area tolling, tolls for ferries, bridges, tunnels, cordon pricing, etc.).

e) The attributes apply to all OBE architectures, and especially to both thin (edge-light) and fat (edge

heavy) client architectures. The interrogator is intended to receive essentially the same information

irrespective of the type of OBE.

It is assumed that the prime objective of the operator of the compliance checking interrogation is to

check whether the user has fulfilled his obligations, especially:
— whether the OBE is mounted in the correct vehicle;
— whether the classification data transmitted by the OBE are correct; and

— whether the OBE is in operational condition, both in a technical and a contractual sense.

Regarding the last point of the above list, on the operational status of OBE, the following model is

assumed.

As long as the OBE signals to the user correct operational status (“green”), the service provider takes

full responsibility for the correct operation of the OBE and for the payment by the user. Hence, as long

as the OBE signals “green” and the user fulfils its other obligations (e.g. entering correct classification

data and not tampering with the OBE), the user can expect the OBE to serve as a valid payment means.

As soon as the OBE signals an invalid operational status (“red”) — either set by the central system of the

service provider (e.g. because the user account is negative), by internal mechanisms of the OBE itself

(e.g. because of a detected defect or an outdated data set) or a user manipulation with such result — the

user knows that the OBE is no longer a valid payment means. The user then has to use alternative

means of toll declaration or payment until the problem is remedied and the OBE is “green” again .

Ultimately, the policy of when to signal “green” or “red” is defined by the service provider in accordance

with the requirements defined by the toll charger(s).

In the case where the OBE status turns “red”, the user has to take action, declare road usage subject to

fees or pay by some alternative means as soon as practicable. Until he does, the user is in a potentially

non-compliant situation. In order to allow a judgment to be made as to whether or not a user has taken

the appropriate action within an acceptable period of time, information is provided by this document

not only on the “green/red” operational status but also on the length of time that the OBE has been in its

current status.

Different toll contexts can overlap geographically. A user could be liable in several toll contexts at once,

e.g. for a nationwide distance-dependent road tax and a local city access pricing scheme — a fact of

which the user might not in all cases be aware. This document builds on the concept that regarding

compliance, there is no notion of toll context as far as possible (see especially 5.4). It is within the

responsibility of the service provider to resolve issues with overlapping toll contexts and to distil all

information into a binary “red/green” message to the user.

A secondary objective of the operator of the compliance checking interrogator might be to collect data

on the performance of the OBE, e.g. in order to check for the correct technical functioning. Since

In this case, “red” and “green” are used in the abstract, symbolic sense, and do not imply any physical implementation.

The design of the user interface of the OBE is implementation-dependent, and several methods for signalling “red” or

“green” are conceivable.

different OBE can work according to quite different principles, the possibilities for doing this in a

standardized way are quite limited. This document contains some provisions for this task (e.g. the

attributes CommunicationStatus, GnssStatus, DistanceRecordingStatus), but otherwise assumes that toll

chargers monitor correct recording by comparing observed traffic (e.g. with cameras) with usage data

received from service providers.

This document has been prepared with the intention to be “minimalist” in the sense that it covers what

is required by operational systems and systems planned in the foreseeable future.

A test suite for checking an OBE or RSE implementation for compliance with this document is defined in

the corresponding edition of ISO 13143-1 and ISO 13143-2.

Electronic fee collection — Compliance check communication for
autonomous systems
1 Scope

This document defines requirements for short-range communication for the purposes of compliance

checking in autonomous electronic fee collecting systems. Compliance checking communication (CCC)

takes place between a road vehicle's on-board equipment (OBE) and an interrogator (roadside mounted

equipment, mobile device or hand-held unit), and serves to establish whether the data that are

delivered by the OBE correctly reflect the road usage of the corresponding vehicle according to the rules

of the pertinent toll regime.

The operator of the compliance checking interrogator is assumed to be part of the toll charging role as

defined in ISO 17573-1. The CCC permits identification of the OBE, vehicle and contract, and verification

of whether the driver has fulfilled his obligations and the checking status and performance of the OBE.

The CCC reads, but does not write, OBE data.

This document is applicable to OBE in an autonomous mode of operation; it is not applicable to

compliance checking in dedicated short-range communication (DSRC)-based charging systems.

It defines data syntax and semantics, but not a communication sequence. All the attributes defined

herein are required in any OBE claimed to be compliant with this document, even if some values are set

to “not defined” in cases where certain functionality is not present in an OBE. The interrogator is free to

choose which attributes are read in the data retrieval phase, as well as the sequence in which they are

read. In order to achieve compatibility with existing systems, the communication makes use of the

attributes defined in ISO 14906 and the ISO 17573 series (all parts) wherever useful.

The CCC is suitable for a range of short-range communication media. Specific definitions are given for

the CEN-DSRC as specified in EN 15509, as well as for the use of ISO CALM IR, the Italian DSRC as

specified in ETSI ES 200 674-1, ARIB DSRC and WAVE DSRC as alternatives to the CEN-DSRC. The

attributes and functions defined are for compliance checking by means of the DSRC communication

services provided by DSRC application layer, with the CCC attributes and functions made available to

the CCC applications at the roadside equipment (RSE) and OBE. The attributes and functions are defined

on the level of application data units (ADUs).
The definition of the CCC includes:
— the application interface between OBE and RSE (as depicted in Figure 2);

— use of the generic DSRC application layer as specified in ISO 15628 and EN 12834;

— CCC data type specifications given in Annex A;

— a protocol implementation conformance statement (PICS) proforma is given in Annex B;

— use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described

in Annex C, Annex D, Annex E and Annex F;

— the informative Annex I highlights how to use this document for the European electronic toll

service (EETS).
