ISO/TS 17427:2014(E)
Introduction
Cooperative-ITS (C-ITS) are a promising and remarkable advancement of Intelligent Transport Systems
(ITS). Numerous cooperative applications are specified that open up new possibilities to make traffic
safer, more efficient and smarter. Technologies are developed and improved to realize and support those
new services and applications. But, to finally implement C-ITS and to achieve the benefits of more safety
and better mobility, various actors from different industries will have to cooperate with each other in a
completely new way. Actors that did not collaborate so far will have to find a way to do so. This requires
a precise definition and assignment of behaviours, responsibilities and liabilities. Therefore a general,
abstract organizational architecture with the description of the single roles, their behaviour and the
corresponding responsibilities is the essential basis for the deployment of C-ITS.
The organizational architecture itself with the description of the roles and responsibilities is a crucial
part of the whole C-ITS architecture. The organizational architectural viewpoint has extensive influences
on the deployment and implementation of C-ITS.
This document describes the high level roles and responsibilities that enable C-ITS Service provision.
TECHNICAL SPECIFICATION ISO/TS 17427:2014(E)
Intelligent transport systems — Cooperative systems —
Roles and responsibilities in the context of cooperative ITS
based on architecture(s) for cooperative systems
1 Scope
This Technical Specification describes the (non-actor specific) roles and responsibilities required
to deploy and operate Cooperative-ITS (C-ITS). The organizational architecture described in this
document is to be used for a fully operational system. The Technical Specification is couched in terms of
[1]
an organizational or enterprise viewpoint, as defined in ISO/IEC 10746 Open Distributed Processing.
This Technical Specification is applicable to all types of road traffic of all classes. The description of
roles is completely technology agnostic and, in terms of C-ITS communication modes, embraces vehicle-
vehicle communications, vehicle-infrastructure communications and infrastructure-infrastructure
communications.
This Technical Specification provides a methodology for the identification of service specific roles
and their corresponding responsibilities based on a process oriented approach. Additionally, the
defined methodology is used to identify the roles and responsibilities for C-ITS, in general. Both the
methodology, as well as, the roles and responsibilities for C-ITS are deduced from the reference model:
[1]
Open Distributed Processing (ISO/IEC 10746). Open Distributed Processing offers five viewpoints
of which the enterprise viewpoint corresponds with the organizational architecture and the roles and
responsibilities.
This Technical Specification separates C-ITS roles into ‘external’ and ‘internal’. Those considered to be
internal are all roles set up for the sole purpose of C-ITS and those considered to be external are all roles
involved in C-ITS but not set up for the sole purpose of C-ITS.
This Technical Specification describes high-level architectural viewpoint on C-ITS. It can be used as a
blueprint when implementing C-ITS and the corresponding organizational structures. The characteristics
of C-ITS entail a huge number of data/information exchanges. Therefore, the implementation of the
organizational architecture stringently needs to respect privacy and data protection, as defined
in ISO/TR 12859 and in the national laws and regulations (where instantiated). Privacy and data
protection affect all roles defined in this Technical Specification and due to these characteristics, all
actors occupying roles in C-ITS need to respect the corresponding standards and regulations.

5 Introduction and theoretical framework
5.1 Transferring ODP to roles and responsibilities for C-ITS
Cooperative-ITS (C-ITS) features the characteristics of a distributed system with its partition onto
multiple ITS stations (3.12). Hence methodologies for the description of distributed systems are consulted
when describing the overall architecture of C-ITS and its different viewpoints. For the description
of the organisational architecture as one of the viewpoints of C-ITS, the concept of Open Distributed
[1] [2] [3]
Processing , , is applied. The organisational architecture corresponds with the enterprise viewpoint
(3.10) in ODP, defining the “purpose, scope and policies governing the activities of the specified system
within the organization of which it is part”. Conveyed to C-ITS, this Technical Specification is part of the
organizational architecture for C-ITS and focuses on the description of C-ITS specific roles (3.20) and
responsibilities (3.18).
Following the concept and terminology of ODP for the description of the roles (3.20) and responsibilities
(3.18), C-ITS can be described as a community (3.5) composed of external and internal enterprise objects
(3.8, 3.9) (see Figure 1) with the objective of providing C-ITS with its benefits regarding traffic safety,
traffic efficiency, comfort and ecologic mobility to the user. External enterprise objects (3.8) are involved
in C-ITS but are not set up for the sole purpose of C-ITS. Therefore this document limits itself to the
identification of roles and responsibilities of external enterprise objects (3.8).
ISO/TS 17427:2014(E)

Roles
5.2 External Enterprise Objects
C-ITS, as internal enterprise object (3.9), is connected with various external enterprise objects (3.8). The
diagram (Figure 2) illustrates the external enterprise objects (3.8) and their interfaces to the internal
enterprise object (3.9). Figure 2 shall illustrate the variety of parties (external enterprise objects) involved
in C-ITS. The external enterprise objects (3.8) comprise examples from different levels.

ISO/TS 17427:2014(E)
Figure 2 — External and Internal Enterprise Objects in a C-ITS Community
From the enterprise objects (3.5) displayed in Figure 2, the following are closely connected with C-ITS
and rather have an external-internal status:
— Telecommunication systems;
— Certification;
— Standardization bodies;
— Authorities.
Criteria for the categorization of “external-internal” is that the external enterprise objects (3.8) are deeply
involved in C-ITS and partially exhibit C-ITS specific roles (3.20). More details are given in Clause 6. The
standard functionalities that external enterprise objects (3.8) provide are documented in the respective
standards referenced in Clause 6.
ISO/TS 17427:2014(E)
Additionally, as shown in Figure 2, C-ITS has interfaces with other ITS systems. These are not explicitly
denominated in this Technical Specification.
5.2.1 Internal Enterprise Objects
C-ITS, as internal enterprise object (3.9), consists of a set of specific roles (3.20) that are identified and
described in the subsequent Clauses. The methodology that describes how these roles and responsibilities
originally were identified and verified can be found in Annex A.
6 Roles and responsibilities
6.1 Introduction
All roles (3.20) and the corresponding responsibilities (3.18) identified through use of the methodology
described in Annex A are described in the following subclauses.
6.1.1 Generic description of organizational architecture
In the generic view of the organizational architecture four major roles (3.20) were identified (Figure 3):
Figure 3 — Global description of Organisational Architecture
6.1.2 System operation
The role (3.20) “‘System operation” is responsible for the proper execution of the applications (3.3) that
provide an end-to-end ITS service(s) (3.23). This includes reliability for the coordination, organization
and execution of the whole process (3.14) from initial data collection to the presentation of the final
service result. One of the major interfaces of this role (3.20) is with the actor(s) (3.2) of the role (3.20)
“Using the service” who receive(s) the service result.
Relationships with other roles (3.20):
The role (3.20) “System operation” is connected with the role (3.20) “System management”. In this
relationship, denominated with the term “managed by” in Figure 3, the actor(s) (3.2) with the role
(3.20) “System management” provide supporting functionalities to the actor(s) (3.2) with the role
(3.20) “System operation”. This mainly includes functionalities enabling and facilitating the “System
management” behaviour (3.4) and responsibilities (3.18).
8 © ISO 2014 – All rights reserved

ISO/TS 17427:2014(E)
The role (3.20) “‘System operation” is connected with the role (3.20) “Policy framework”. In this
relationship, denominated with the term “governed by” in Figure 3, the actor(s) (3.2) with the role
“Policy framework” provide policies and regulations as well as their enforcement to the actor(s) (3.2)
with the role (3.20) “System operation”.
The role (3.20) “System operation” is connected with the role (3.20) “Using the system”. In this
relationship, denominated with the term “used by” in Figure 3, the actor(s) (3.2) with the role (3.20)
“System operation” provide the achieved results to the actor(s) (3.20) with the role (3.20) “Using the
system”. The role (3.20) “Using the system” make(s) use of these results.
6.1.3 Using the system
The role (3.20) “Using the system” is responsible to perform an appropriate reaction to the service result
received from the actors (3.20) with role (3.20) “System operation”. The role (3.20) “Using the system”
might stimulate the role (3.20) “System operation” (trigger an ITS service (3.23)).
6.1.4 System management
The role (3.20) “System management” is responsible to fulfil all required management activities within
the system, this especially includes activities supporting “System operation”. Additional actions (3.1)
are the management of the “Policy framework” activities.
Relationship with other roles (3.20):
The role (3.20) “System management” is connected with the role (3.20) “Policy framework”, in this
relationship, denominated with the term “managed by” in Figure 3, the actor(s) (3.2) with role (3.20)
“System management” provide supporting functionalities to the actor(s) (3.2) with the role (3.20) “Policy
framework”. This mainly includes functionalities enabling and facilitating the “Policy Framework”
behaviour (3.4) and responsibilities (3.18). Additionally the actor(s) (3.2) with the role (3.20) “Policy
framework” provide(s) policies and regulations as well as their enforcement to the actor(s) (3.2) with
the role (3.20) “System management”. This is denominated with the term “governed by” in Figure 3.
6.1.5 Policy framework
The role (3.20) “Policy framework’ is responsible for all governing and institutional activities required
in the system.
Relationship with other Roles (3.20):
See above (“System operation”, “System management”). Relationships of role (3.20) “Policy Framework”
with role (3.20) “System Operation” and role (3.20) “System Management” have already been given in
subclauses 6.2.1 and 6.2.3.
The three main roles (3.20) “System operation”, “System management” and “Policy framework” are
detailed with sub-roles. Those are described in the following subclauses. The role (3.20) “Using the
service” is not further detailed, a more detailed description of its responsibilities is appended.
6.2 General responsibilities of actors involved in C-ITS
6.2.1 Registration and authorization
Prior to the use of the system each role (3.20) and, therefore each actor (3.2), shall be responsible to
participate in activities related to the request of access permission. This includes both registration and
authorization:
— Registration – defined as registration to the system itself, necessary prior to the first use of the
system (compare with sign-up):
— issue request for registration to the system,
ISO/TS 17427:2014(E)
— receive certificates for registered ITS Stations.
— Authorization – defined as authorization prior to every system usage (comparable to sign-in):
— issue request for authorization,
— receive confirmation of authorization.
Details of the activities following the registration or authorization request and leading to the reception
of a permission or confirmation base on the standard registration and authorization mechanisms
defined in ISO 14817.
6.2.2 Privacy and Data Protection
The definition of C-ITS, as stated in ISO 17465, mentions two core characteristics of C-ITS: (a) The
distributed implementation of ITS services (3.23), which requires a huge number of data and information
exchanges between ITS Stations (3.12) to realize the respective end-to-end ITS service (3.23) and, (b)
The sharing of data and information between ITS Stations (3.12) for purposes other than the original
intent. Both properties lead to serious consequences on C-ITS regarding privacy and data protection.
ISO/TR 12859 provides a detailed description of privacy and data protection issues for C-ITS, as a whole.
Additionally, this important subject needs to be reflected in every single C-ITS standard including this
Technical Specification. It will be one of the major tasks of the actors (3.2) that claim one of the roles
(3.20) defined in this Technical Specification to respect the responsibilities (3.18) regarding privacy and
data protection.
Much of the data/information collected and processed in C-ITS can be associated with an individual.
This especially applies to any kind of data/information collected through a vehicle (floating car data)
including any ITS Station that is moving e.g. mobile device. Therefore this content is subject to strict
privacy and data protection Regulations and the roles (3.20) collecting or handling this content have to
respect the corresponding regulations.
Each role (3.20) and, therefore each actor (3.2), is responsible to respect both ISO/TR 12859 and national
regulations and laws on privacy and data protection when participating in C-ITS.
In general, this applies for the following actions (3.1):
— Collection of data/information (content): each actor (3.2) collecting data/information (including
the hand-over of data/information from other parties) handles this data/information with care and
respect the originators privacy based on the principles outlined in ISO/TR 12859;
— Processing of data/information (content): each actor (3.2) processing data/information handles
this data/information with care and complies with the principles outlined in ISO/TR 12859;
— Deletion of data/information (content) after usage: each actor (3.2) handling data/information
ensures the proper deletion of data/information after usage based on the principles outlined in
ISO/TR 12859;
— Transmission of data/information (content): each actor (3.2) providing an ITS service (3.23)
that transmits data/information complies with the principles outlined in ISO/TR 12859.
Any role (3.20) described in the following Clauses is, in a way, in touch with data/information collected
or used in C-ITS and, therefore, needs to comply with these requirements.
6.3 Role: System operation

ISO/TS 17427:2014(E)
The role (3.20) “System operation” is composed of the sub-roles (3.21) content provision, service
provision and presentation provision. The mentioned sub-roles share the responsibilities (3.18) of the
role (3.20) “System operation”. The role (3.20) “System operation” itself bundles all responsibilities (3.18)
of the sub-roles (3.21).
6.3.2 Sub-role: Content provision
The sub-role (3.21) “Content provision” shall provide various types of content. This includes every type
of data between raw data and highly (pre-) processed information.
Prior to the provision of content the sub-role (3.21) shall be responsible for the registration of itself as a
content provider and the content that is provided:
— subscribe content provision activity,
— cancel content provision activity,
— registration of content (data/information),
— cancel/deregistration of content (data/information).
Details of content (data/information) registration related activities can be found in ISO 14817.
The responsibilities (3.18) associated with this sub-role (3.21) that have a tight relation to the “Service
provision” itself are:
— receive content request,
— obtain content (data/information),
— provide content (data/information).
Additionally the role ‘Content Provision’ is responsible for ensuring data integrity.
6.3.3 Sub-role: Service provision
The sub-role (3.21) “Service provision” shall connect the sub-role (3.21) “Content provision” with the sub-
role (3.21) “Presentation provision”.
The sub-role (3.21) “Service provision” identifies which algorithm is suitable to fulfil the end-to-end
ITS service (3.23), it determines the content that is required to run the ITS service (3.23), afterwards
runs the ITS service (3.23) and provides a suitable service response. The content required to run the
ITS service (3.23) is requested and received from the sub-role (3.21) “Content provision”. The service
results shall be delivered to the sub-role (3.21) ”Presentation provision”.
Prior to the provision of the ITS service (3.23), the registration of the ITS service (3.23) with the role
(3.20) “Service catalogue management” shall be required. The sub-role (3.21) ”Service provision” shall
be responsible for the activities:
— subscribe new ITS service (3.23),
— cancel/deregistration of ITS service (3.23).
Details of these activities are described in ISO/TS 17419.
The responsibilities (3.18) related to the sub-role (3.21) “Service provision” that have a tight link to the
execution of the service itself are:
— receive service request,
— select ITS service (3.23)/ application (3.3)/algorithm,
— operate ITS service (3.23)/ application (3.3)/ algorithm (service generation),
ISO/TS 17427:2014(E)
— request content (data/information) for service execution,
— receive content (data/information) for service execution,
— provision of service (result).
6.3.4 Sub-role: Presentation provision
The sub-role (3.21) “Presentation provision” shall be responsible for the suitable presentation of the
service results. This includes the scheduling of presentations, the prioritization of information to be
presented and the selection of the presentation mode (visual, auditory, tactile).
Responsibilities (3.18) tied to the sub-role (3.21) are:
— receive service results,
— scheduling of presentations,
— prioritization of service results,
— selection of presentation mode,
— conformance of presentation with regulation(s).
6.4 Role: Using the service
The role (3.20) “Using the service” incorporates the triggering of ITS services (3.23) available within the
system. The entity occupying the role therefore issues service requests and receives service responses.
The responsibilities (3.18) related to the role (3.20) “Using the service” therefore have a tight relation to
the service operation itself:
— issue service request,
— recognition of service result presentation,
— judge the need for reaction,
— react accordingly.
6.5 Role: System management
The role (3.20) “system management” is responsible for all management activities in the system. It
supports both “System operation” and “Policy framework”.
The sub-roles (3.21) of the role (3.20) “system management” are derived from the ones defined in ITIL V3
[17]
(Information Technology Infrastructure Library). Not all roles (3.20) from ITIL V3 will be used in
C-ITS – the appropriate ones regarding level of detail and C-ITS characteristics were selected. Where
necessary, roles (3.20) were merged and renamed.
Despite the revision and adaptation of the ITIL V3 roles (3.20) the remaining roles (3.20) can partially
be grouped. This is announced in the text accompanying the following descriptions.
System management is a distributed role (multiple entities).
6.5.1 Sub-role: Service catalogue manager
This sub-role (3.21) shall be responsible for up-to-date maintaining of the service catalogue that lists all
registered ITS services (3.23) and their status. This includes:
