Foreword

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.

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

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT) see the following URL: Foreword - Supplementary information.

The committee responsible for this document is ISO/TC 204, Intelligent transport systems.

ISO/TR 17465 consists of the following parts, under the general title Intelligent transport systems —

Cooperative ITS:
— Part 1: Terms and definitions
— Part 2: Guidelines for standards documents

ISO/TR 17465-2:2015(E)
Introduction

As Cooperative-ITS involves many services provided using a large number of applications all

communicating with each other and sharing data, it is very likely that some standards will become

very large. This will be particularly true where a particular standard documents the requirements for a

particular service or set of applications. It is thus likely that in some instances, multi-part standards will

be required so that finding particular aspects of a standard can be made easier.

In order for users to quickly find the standard’s information that they require in multi-part standards,

this part of ISO/TR 17465 provides guidance on the common structure to be used for the parts in

these multi-part standards. This will mean that a specific number is always used for each part, so that

Architecture/Application will always be part 1, ITS-station Management will always be part 2, Security

Set will always be part 3, etc. This part of ISO/TR 17465 also describes the relations between the

different parts of these standards, e.g. the relationship between architectural elements and data sets.

The use by multi-part standards of the structure described in this Technical Report does not remove the

obligation for those creating standards to involve other Technical Committees and/or Working Groups

in the creation of a particular standard. Thus, for example, the part of the standard that describes the

provisions for protection of privacy data and requirements for security of data and data transmissions

should be created in explicit coordination with the CEN/ISO working group responsible for overall C-ITS

Security and Privacy.

The need for the involvement of other Technical Committees and/or Working Groups will depend on the

scope and contents of the multi-part standard. There might be need for this involvement to be identified

in the New Work Item Proposal from which the multi-part standard is to be created and for a template

to be created so that this is done in a consistent way for all multi-part standards.

This Technical Report is thus only for use with standards that relate to Cooperative-ITS. Its contents

need not be applied to the ISO TC 204 and CEN TC 278 standards that do not specify information

exchanges because they are not relevant to those standards (such as standards for stand-alone systems

that acquire information only from sensors).

TECHNICAL REPORT ISO/TR 17465-2:2015(E)
Intelligent transport systems — Cooperative ITS —
Part 2:
Guidelines for standards documents
1 Scope

This part of ISO/TR 17465 provides guidance for the structure that is to be used in multi-part ISO/CEN

standards for particular services or applications to be included in Cooperative-ITS. The guidance in this

part of ISO/TR 17465 may also be considered for use in multi-part standards for other ITS services and

applications.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
Cooperative-ITS
C-ITS

subset of overall ITS (2.2) that communicates and shares information between ITS stations (2.5) and ITS

applications (2.3) to give advice or facilitate actions with the objective of improving safety, sustainability,

efficiency, and comfort beyond the scope of stand-alone systems

Note 1 to entry: For further details and the justification of this definition, see ISO/TR 17465-1.

2.2
intelligent transport system
ITS

transport systems in which advanced information, communication, sensor and control technologies,

including the internet, are applied to increase safety, sustainability, efficiency, and comfort

2.3
ITS application

instantiation of an ITS service (2.4) that involves an association of two or more complementary ITS-S

application processes (2.6)

Note 1 to entry: Fragments of an application may also reside in nodes that are not ITS stations (2.5).

[SOURCE: ISO 21217:2014, 3.9]
2.4
ITS service

functionality provided to users of intelligent transport systems (2.2) designed to increase safety,

sustainability, efficiency, or comfort

Note 1 to entry: From an abstract point of view, the term “ITS station” refers to a set of functionalities. The

term is often used to refer to an instantiation of these functionalities in a physical unit. Often, the appropriate

interpretation is obvious from the context. The proper name of the physical instantiation of an ITS-S is ITS station

unit (ITS-SU) (2.8).

4 Organization of multi-part Cooperative-ITS standards
4.1 Overview

It is envisaged that standards for ITS-S application processes in Cooperative-ITS will need to cover many

aspects of their design and operation. This is because by its very nature, Cooperative-ITS will involve a

number of actors, data from different sources, and information being sent to a variety or recipients, possibly

needing to use more than one communications mechanism and a variety of interfaces. There will also be

other standards relating to more generic issues such as roles and responsibilities that will be needed.

To aid the use of these standards, it will be advantageous if the standards that relate to a particular

Cooperative-ITS service and/or application have a single number. Each standard would be made up of a

number of parts, the number being dependent on the scope of the service and/or application. The parts

2 © ISO 2015 – All rights reserved
---------------------- Page: 7 ----------------------
ISO/TR 17465-2:2015(E)

would each be a separate standards document, written using the ISO template. This type of approach is

already quite common for large and complex standards in other areas of ITS, but as yet the parts do not

always follow a common structure. Although this lack of a “common structure” enables a very flexible

approach to be adopted for standards creation, it can actually make the task of finding the appropriate

part of a standard very difficult for their users. This is because if a user is only interested in a particular

aspect of a standard (e.g. interfaces, data used, architecture), all the parts have to be searched to find the

one containing the aspect that is of interest. What would make the task of searching much easier is the

application of a common structure for the numbering of the parts in each standard.

4.2 Structure of parts for Cooperative-ITS standards
4.2.1 Overview

The common structure of parts for the aspects that are to be included in multi-part standards for

Cooperative-ITS services and/or applications is shown in Table 1.
Table 1 — Organization of the parts in a multi-part Cooperative-ITS standard
Content Part number
Architecture/Application base standard 1
ITS station management 2
Privacy 3
Data 4
Interfaces 5
Network/protocols 6
Identifiers 7
Facilities/API’s 8
Conformance testing 9
Security 10

The possible identities of the standards that relate to each part will be discussed in more detail in 4.3.

4.2.2 Use of annexes instead of parts

It should be noted that the need for separate parts will depend on the application being covered by

the standard. For some applications, annexes may be created and added to part 1 (the base standard)

instead of one or more of different parts shown above.

If the result of the use of annexes as just described is that none of the other parts are required, then

there is no need to call the remaining single standard part 1. This means that only a single standards

document will be produced.
4.2.3 Contents of part 1

The set of documents for each Cooperative-ITS standard will always have a part 1. This is the “base”

standard and should provide all the basic information for the ITS application(s) that the standard covers.

In addition, part 1 should also contain a short description of all the other parts in the standard. Each

part will also, as a minimum, contain a table (see Table 1) so that if the user does not initially open part 1,

they will realize that they are looking at a multi-part standard and can easily identify which other parts

are relevant.

The following example shows the different lists of parts that would appear in part 1 of a multi-part

Cooperative-ITS standard. It has been assumed that the Cooperative-ITS application to which this

© ISO 2015 – All rights reserved 3
---------------------- Page: 8 ----------------------
ISO/TR 17465-2:2015(E)

particular multi-part standard relates to does not have a scope that necessitates the use of the full range

of parts shown in Table 1.
Part 1: Architecture/application base standard this document
Part 2: ITS station management ISO xxxxx–2
Part 3: Privacy ISO xxxxx−3
Part 4: Data not relevant
Part 5: Interfaces ISO xxxxx−5
Part 6: Network/protocols ISO xxxxx−6
Part 7: Identifiers not relevant
Part 8: Facilities/API’s ISO xxxxx−8
Part 9: Conformance testing ISO xxxxx−9
Part 10: Security ISO xxxxx−10

NOTE The value “ISO xxxxx” represents a theoretical C-ITS standard that can be created.

4.2.4 Contents of part 2 to part 10

What needs to be defined for each of the other parts of the standard identified in Table 1 (part 2 to

part 10) will be the subject of separate standards that are relevant to each part. Two examples of these

standards are ITS Station Management, which will be defined in ISO 17423, and the identifier set which

will be defined in ISO 17419.

The following example shows the different lists of parts that would appear in part 8 of a multi-part

Cooperative-ITS standard. Again, it has been assumed that the Cooperative-ITS application to which

this particular multi-part standard relates to does not have a scope that necessitates the use of the full

range of parts shown in Table 1.
Part 1: Architecture/application base standard ISO xxxxx−1
Part 2: ITS station management ISO xxxxx−2
Part 3: Privacy ISO xxxxx−3
Part 4: Data not relevant
Part 5: Interfaces ISO xxxxx−5
Part 6: Network/protocols ISO xxxxx−6
Part 7: Identifiers not relevant
Part 8: Facilities/API’s this document
Part 9: Conformance testing ISO xxxxx−9
Part 10: Security ISO xxxxx–10

NOTE The value “ISO xxxxx” represents a theoretical C-ITS standard that can be created.

4.2.5 Further illustration of arrangement of parts

Three further illustrations of how the Parts in multi-part Cooperative-ITS standards would be numbered

using the principles set out in Table 1 is shown in Table 2.
Table 2 — Part numbers for a set of different standards
ISO xxxxx ISO yyyyy ISO zzzzz
Aspect Part numbers Part numbers Part numbers
Architecture/application base ISO xxxxx-1 ISO yyyyy-1 ISO zzzzz-1
standard
ITS station management ISO xxxxx−2 ISO yyyyy−2 ISO zzzzz−2
Privacy ISO xxxxx−3 ISO yyyyy−3 not relevant
Data not relevant ISO yyyyy−4 not relevant

NOTE The values “ISO xxxxx”, “ISO yyyyy” and “ISO zzzzz” represent theoretical C-ITS standards that may be created.

---------------------- Page: 9 ----------------------
ISO/TR 17465-2:2015(E)
Table 2 (continued)
ISO xxxxx ISO yyyyy ISO zzzzz
Aspect Part numbers Part numbers Part numbers
Interfaces ISO xxxxx−5 not relevant ISO zzzzz−5
Network/protocols ISO xxxxx−6 not relevant ISO zzzzz−6
Identifiers not relevant ISO yyyyy−7 ISO zzzzz−7
Facilities/API’s ISO xxxxx−8 not relevant ISO zzzzz−8
Conformance testing ISO xxxxx−9 ISO yyyyy−9 ISO zzzzz−9
Security ISO xxxxx−10 ISO yyyyy−10 ISO zzzzz−10

NOTE The values “ISO xxxxx”, “ISO yyyyy” and “ISO zzzzz” represent theoretical C-ITS standards that may be created.

Again, it should be noted that the need for all of the separate parts shown above will depend on the

application being covered by the standard. For some applications, annexes may be created and added to

part 1 (the base standard) instead of one or more of different parts shown above. As noted in a previous

clause, if a consequence of the use of annexes is that none of the other parts are required, then there is

no need to call the remaining single standard part 1. This means that only a single standards document

will be produced.
4.2.6 What if a particular part is very small?

If the content of a part happens to be very small, i.e. less than three pages, then its contents should be

included as annex to part 1. This means that the contents of Table 1 and Table 2 would not reference a

particular part but would point to the relevant annex in part 1, e.g. “See ISO xxxxx–1, Annex A”. This will

avoid the need to obtain a separate standard for less than three pages of content.

4.2.7 What happens if a particular part is not needed?

If a part is not needed because the aspect that it should cover is not relevant to a particular Cooperative-

ITS application, then it should be omitted and shown as being “not relevant” in the list of parts. In this

case however, the numbering of the parts would always remain the same. This means that part 8 will

always be the “Facilities/API Set” in every multi-part standard for Cooperative-ITS applications even if

some or all of part 3 to part 7 do not exist.
4.2.8 Need for coordination

The use of multi-part standards of the structure described in the clauses of this Technical Report, does

not remove the obligation for those creating standards to involve other Technical Committees and/or

Working Groups in the appropriate aspects of the creation of a particular standard. Thus, for example,

part 3 and part 11 of the multi-part standard that describe the provisions for protection of privacy data

and requirements for security of data and data transmissions should be created in explicit coordination

with the CEN/ISO working group responsible for overall C-ITS security and privacy.

The need for the involvement of other Technical Committees and/or Working Groups will depend on the

scope and contents of the application(s) for which the multi-part standard is being created. It may in fact

be beneficial to identify the need for and scope of this involvement to be identified in the New Work Item

Proposal that describes the need for the creation of a multi-part standard. As an aid to this, a modified

version of the existing New Work Item Proposals template could be created so that the identification is

done in a consistent way for all multi-part standards

ISO/TR 17465-2:2015(E)
4.3 Descriptions of the scope of each part of a Cooperative-ITS standard
4.3.1 Overview

In order to avoid confusion and to ensure that all the parts across all Cooperative-ITS standards are consistent

in what they include, they should be based on the particular base standard that applies to the aspect that

they describe. The following clauses provide descriptions of what should be the content of each part.

4.3.2 Part 1: Architecture/application

As will be expected from the definition given in ISO/TR 17465-1, Cooperative-ITS consists of a subset

of the total scope of ITS services that shares necessary information across multiple ITS-S application

process areas, e.g. information generated for safety purposes can be used for efficiency applications.

The architecture showing the required ITS stations and the ITS-S application processes that they will

host will be described in this part of the standard, together with a detailed description of the service,

which, uses as its starting point, the list of ITS services provided in ISO 14813-1.

Using the ITS service description and the architecture as its starting points, this part of the standard

will also provide an overall description of the functional requirements for the ITS-S application

process(s) that are needed to deliver the ITS service(s). This description should be sufficient for readers

to understand how the ITS-S application process(es) should work(s) and what data it(they) will need to

exchange with functionality located elsewhere.

Other information about the ITS-S application process (e.g. organizational architecture and roles and

responsibilities) should be included to enable the other parts (or lack of them) in the multi-part standard

to make some sense. Again, this information should be based on what is available in the relevant

standards, e.g. ISO 17427 for roles and responsibilities.

If particular parts are not included in a multi-part Cooperative-ITS standard, then the reasons for their

exclusion should be stated in part 1. These reasons may include the fact that the required standards

information is provided by another standard or that the information they could contain has been

included in an annex to part 1, because it is insufficient to warrant the creation of a particular part for

this standard.
4.3.3 Part 2: ITS station management

The basics of ITS communications and related management and security features based on the ITS

station architecture is specified in ISO 21217:2014, 7.2.

Implementations of the ITS station architecture, i.e. ITS station units (ITS-SUs), need to be compatible

and/or interoperable and operate within a common framework. ISO 21217:2014 specifies an overall

architecture for ITS stations and their interactions. Other relevant standards are:

ISO 21218 complements ISO 24102–1 for management of communication interface;
ISO 24102–1 specifies local ITS station management;
ISO 24102–2 specifies remote ITS station management;

ISO 24102–3 specifies service access points in an ITS station related to station management and

security issues;

ISO 24102–4 specifies ITS station-internal management communications for distributed imple-

mentations of ITS-SUs;

ISO 24102–5 specifies ITS service advertisement, especially the management of session set-up;

ISO 24102–6 specifies path and flow management, i.e. how to set up and maintain communication

links;
6 © ISO 2015 – All rights reserved
---------------------- Page: 11 ----------------------
ISO/TR 17465-2:2015(E)

ISO 17419 defines globally unique identifiers and addresses, related registries and functional

usage of them to ensure trust and proper operation of ITS-SUs;

ISO 17423 defines ITS application requirements and objectives for communications in order to

abstract ITS applications from communication tools in an ITS-SU, which complements

ISO 24102–6.

This part will also need to discuss how the ITS station will need to be managed. This may need to take

into account the possible need to distribute the ITS-S process applications over several physical “boxes”

in its operation, or for it to be distributed across several ITS stations, e.g. collect data from multiple ITS

stations in several vehicles, for each of them to transfer that data to a roadside ITS station which will

fuse and extract the core data, before sending it back to (possibly different?) vehicle ITS stations and in

the form of a report to a central ITS station.
4.3.4 Part 3: Privacy

Personal privacy protection will need to be protected in accordance with the local data privacy regulations

applicable within any jurisdiction and must respect the international privacy regulations. Details of

these can be found in ISO/TR 12859 (Privacy aspects in ITS standards and systems). Jurisdictions may

impose regulations and carry out audits to protect personal privacy. Such measures are not defined

within this Technical Report and will be included in another standard.

Guidance on privacy aspects and associated legislative requirements is again provided by ISO/TR 12859

and new standards for privacy are being produced. The privacy aspects that may need to be taken

into consideration during the design and implementation of Cooperative-ITS applications include,

determinati
