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).

The committee responsible for this document is ISO/TC 204, Intelligent transport systems.
This second edition cancels and replaces the first edition (ISO 14813-1:2007), which has been
technically revised.
ISO 14813 consists of the following parts, under the general title Intelligent transport systems —
Reference model architecture(s) for the ITS sector:
— Part 1: ITS fundamental services
— Part 5: Requirements for architecture description in ITS standards
— Part 6: Data presentation in ASN.1

Introduction
Intelligent transport systems (ITS) service domains and groups reflect the evolution of technology-
oriented transportation practices and applications. So far this has been in the road transport domain,
but ITS is beginning to appear in the maritime and rail transport domains. This has become of
increasing importance and interest as the scope of ITS expands beyond its original range of services
in road traffic management, traveller information and electronic payment systems. ITS is now also
expected to address services in the following areas of the road transport domain:
— Transport network operations and maintenance activities;
— Freight mobility and inter-modal connectivity;
— Multi-modal travel including both pre-trip and on-trip information and journey planning where the
trip starts and/or finishes in the road transport domain;
— Variable road pricing strategies for freight and personal travel;
— Emergency and natural disaster-related response activities and coordination;
— National security needs related to transportation infrastructure;
— Cooperative-ITS – sometimes referred to as ‘connected vehicles’ or ‘connected vehicle/highway
systems’.
Services in some of the areas identified above also interface with more generalized activities and
environments outside the road transport domain. For example, it is possible for road pricing and revenue
systems activities to interface with electronic commerce, or eCommerce activities, and thus utilize
standards and principles associated with the banking industry along with generally accepted accounting
principles. The addressing of national security and coordination issues also requires addressing specific
national standards related to civil defence, emergency communications, and other procedures. These
interfaces, while largely outside the scope of TC 204, are nevertheless critical external influences on the
functionality of the various services supported by ‘ITS service domains and groups’.
The standards that have been developed within TC 204 must all be mapped to one or more of the ITS
domains, service groups and services described in this part of ISO 14813. Additionally, the development
of a standard international data dictionary and registry for ITS requires the ability to address both
current and emerging services that ITS can provide.
To this end, the ITS service domains, groups and services presented in this part of ISO 14813 serve
as a framework for developing ITS architectures and ITS-related concepts of operation, which in turn
lead to the definition of the appropriate requirements, functionality and standards necessary to deploy
specific ITS services. As the range of transportation activities that utilize ITS tools has broadened, the
original ‘fundamental services’ developed by TC 204 are now revised and expanded into ‘ITS service
domains and groups’.
Figure 1 illustrates the hierarchy of functional definitions, and how they might be used as the input to
ITS architectures. The Service Domains that apply to ITS are listed in 6.1 with each defining the nature
of the activities provided. Each of these Domains is then covered by separate annexes in this part of
ISO 14813, each of which includes the descriptions of its own Service Groups and Services. The Service
Groups describe more specific activities that are part of the Domain and the Services provide the more
detailed description of what is provided within each Service Group.
The way in which the descriptions of the services are used in ITS architectures depends on the
methodology that has been adopted for their creation. Thus the service descriptions can be used
to generate ‘use cases’ which are the input to an ITS architecture created using object orientated
methodology (see other parts of the ISO 14813 series), or ‘user needs’, which are the input to an ITS
architecture created using the process orientated methodology (see ISO/TR 26999).
Figure 1 — ITS services — Hierarchy of definitions for ‘ITS reference architecture’
In order to develop a cohesive reference architecture, and in order to establish the relationship and
interdependencies of the various ‘intelligent transport systems’ (ITS) services, it is beneficial to firstly
determine the underlying ITS services. Thus, the purpose of this part of ISO 14813 is to identify the ‘ITS
service groups’ and the domains within which the Service Groups reside, within the current perception
of the ITS sector.
‘ITS service domains and groups’ , while they build upon existing U.S., European Union, Japanese and
other international and national taxonomies, or classification systems, can also provide a common
descriptive basis for comparing these taxonomies, as well as others being developed throughout the world.
Currently there are many instantiations of ITS architecture in use around the world, with fragments
of ITS architectures being used as the basis for several International Standards. This part of ISO 14813
embraces architecture concepts from the following sources:
— Other ITS architecture activities from several parts of the world, including the US National ITS
Architecture and the European ITS Framework (FRAME) Architecture;
— Other ISO TC 204 and CEN TC278 working groups.
Most if not all ITS architectures that are in use around the world are based on either the US National ITS
Architecture or the European ITS Framework (FRAME) Architecture. Unfortunately, the terminology
used by these two ITS architectures is similar but not identical. The following table provides a high-
