Introduction
This document is part of a family of deliverables from Standard Development Organizations (SDOs)
for Cooperative Intelligent Transport Systems (C-ITS), which is a subset of standards for Intelligent
Transport Systems (ITS).
ITS aims to improve surface transportation in terms of:
— safety
e.g. crash avoidance, obstacle detection, emergency calls, dangerous goods;
— efficiency
e.g. navigation, green wave, priority, lane access control, contextual speed limits, car sharing;
— comfort
e.g. telematics, parking, electric vehicle charging, infotainment;
— sustainability
by applying information and communication technologies (ICT).
The whole set of standards for deployment of C-ITS is difficult to understand by developers of equipment
and software, especially ITS application software, and thus guidelines explaining a beneficial choice
of standards (C-ITS Release), the purpose and interaction of standardized features, beneficial
implementation approaches and guidance in developing ITS applications are a prerequisite for a fair
and open market allowing early deployment of interoperable and future-proof solutions.
The ISO 21186 series provides necessary guidelines in multiple parts, each dedicated to a specific
purpose:
— Part 1: Standardization landscape and releases (this document);
[32]
— Part 2: Hybrid communications ;
[33]
— Part 3: Security .
This document can be complemented by further parts as required, for example:
— Usage of the service announcement protocol specified, for example, in ISO 22418;
— Dynamically extendable data and protocol parameters ("Information Object Classes" and
"Information Object Sets"; based on ASN.1 type CLASS);
— Usage of the GTDM framework specified in ISO/TS 21184.
For deployment of ITS, especially C-ITS and the emerging Urban ITS and "Mobility as a Service" (MaaS)
paradigms, consistent and complete sets of standards and profiles of standards including necessary
parameterization are necessary in support of the targeted ITS services to be provided by means of ITS
applications. Such sets are referred to as "C-ITS Release". This document presents the C-ITS standards
landscape, describes a concept of Releases and exemplifies this concept with a "C-ITS Release 2".
At the time of writing this document, no applicable Intellectual Property Rights (IPR) issues were
known related to this document. However, this document references standards, for which IPRs are
known. Information on such IPRs is expected to be provided in those respective standards, which might
be from any one of the Standards Development Organisations working on ITS or C-ITS.
Referencing other SDOs and their respective deliverables is in no way to be understood as an
endorsement, but rather as an informative piece of information.
More details on the C-ITS domain can be found in the Brochure cited in Reference [129].

4 Standardization at SDOs
4.1 General
Standardization in general is the process of generating specifications by a recognized authority, i.e. an
SDO, applying the principle of consensus finding prior to formal approval by voting according to the
rules of the SDOs.
Regulatory requirements complement standards and specifications and should be considered for the
deployment of equipment and the operation of services in the given regulatory domain.

4.2 Goals of standardization
The purpose of standardization, in general, is to enable or facilitate services of the respective
standardization domain, i.e. C-ITS services provided by ITS applications for the ITS service domains.
Particularly, the purpose of standardization is manifold, for example, aiming at:
— technical interoperability at observable communications interfaces (covering, for example,
mechanical, electrical, and logical requirements);
— portability of applications (enabling, for example, the online download of applications from station
management centres and the execution of them on different technical platforms);
— syntactical and semantical interoperability in terms of data and messages;
— minimum functionality from the users' point of view;
— minimum performance to ensure reliable execution of use-cases;
— facilitation of implementations;
— reliable protected operations in terms of privacy and (cyber) security;
— provision of commonly agreed terms and definitions, i.e. a common language;
— commonly agreed modes of operation, i.e. work methods;
— a global market;
— prevention of vendor-lock-in; and
— evidence of compliance.
An introduction to C-ITS services is provided in Clause 5.
4.3 Releases
In order to reach the standardization goals listed in 4.2, standards are grouped in so-called "Releases",
together with information on profiles and parameters. Profiles identify selected mandatory
requirements, and parameter information identifies applicable values, such that interoperability
between equipment provided by different vendors is ensured.
Releases use dated references to standards. A release supports one or several use cases or services.
The Bibliography presents a non-exhaustive snapshot of SDO deliverables that are considered to be of
certain relevance for ITS, especially for C-ITS but also for the Urban ITS paradigm.
Clause 6 explains the approach towards C-ITS releases and provides examples of releases.
4.4 SDOs
Major standard development organizations (SDOs), e.g. ISO, CEN, ETSI, IEEE, working on an international
or regional level provide deliverables, e.g. standards, specifications, reports, for the domain of C-ITS.
Secondary SDOs in the sense of the C-ITS business domain are working on general purpose specifications
that are usually referenced in ITS standards.
For the deployment of ITS, regional legislation is to be considered, e.g. in Europe:
— Decisions of the European Commission;
— Recommendations and Decisions from CEPT's ECC / ERC;
— Delegated Acts of the European Commission.

More details on "who is doing what" are presented in the Brochure .
4.5 Standardization areas
Standardization activities can be grouped into standardization areas. For the purpose of this document,
this grouping follows largely the ITS station architecture specified in ISO 21217 and illustrated in
Figure 1.
Figure 1 — Simplified ITS station architecture (ISO 21217)
The "Harmonized Architecture Reference for Technical Standards" (HARTS) project applied the same
[128]
architectural approach using slightly different terms .
The following standardization areas are identified and used in this document:
— A-1: System level issues
High level system architecture and related issues, i.e. the environment in which ITS-SUs according
to Figure 1 operate.
— A-2: Station architecture
Primarily the general framework illustrated in Figure 1.
— A-3: ITS applications, messages, data
Issues related to use cases and related applications (procedural behaviour) and their respective
communications (data and messages) that are typically architecturally located in the Applications
and Facilities blocks of Figure 1.
— A-4: Station management
Management of issues related to whole ITS-SU covering e.g. local station management and remote
station management.

---------------------- Page: 15 ----------------------
SIST-TP CEN ISO/TR 21186-1:2021
ISO/TR 21186-1:2021(E)
— A-5: Security
Issues mainly architecturally located in the Security block of Figure 1; these issues include
interactions between the Security block and basically all other blocks of Figure 1. Note that security
also includes privacy.
— A-6: Access layer technologies
Communications issues architecturally located in the Access block of Figure 1, i.e. the functionality
of the OSI layers 1 and 2.
— A-7: Network and Transport layer technologies
Communications issues architecturally located in the Networking and Transport block of Figure 1,
i.e. the functionality of the OSI layers 3 and 4.
— A-8: Facility layer technologies
Issues related to communications and applications, architecturally located in the Facilities block of
Figure 1, i.e. the functionality of the OSI layers 5, 6, and 7.
— A-9: Protocol stack
Issues related to a combination of A-6, A-7, and A-8.
Within each standardization area, possible subjects of an SDO deliverable are distinguished by means
of categories of SDO deliverables; see 4.6.
4.6 Categories of SDO deliverables
The following standards categories, applicable for the various standardization areas presented in 4.5,
are identified and used in this document:
— C-1: Preparatory investigations
The major topic is the provision of results on investigations aiming on identifying potential future
standardization activities.
— C-2: Functional requirements
The major standardization topic is the provision of functional requirements without going into the
details of specifications of e.g. protocols, data, or messages.
— C-3: Use cases
The major standardization topic is the provision of use case specifications and related illustrations.
— C-4: Data and messages
The major standardization topic is the provision of definitions of data, also referred to as "data
dictionaries", or the specification of messages, typically based on standardized data.
— C-5: Protocols
The major standardization topic is the provision of protocol specifications, e.g. communications
protocols and procedural behaviour of applications.
— C-6: Profiles
The major standardization topic is the provision of profiles based on existing standards, e.g. a
[38] [112]
communication profile based on the tool box IEEE 802.11 (WiFi).

ISO/TR 21186-1:2021(E)
— C-7: Testing
The major standardization topic is the provision of test specifications, e.g. conformance test suites.
Conformance test suites typically consist of three parts, i.e.
1) a (Protocol) implementation conformance statement proforma (PICS) allowing a vendor to
declare conformance with selected features;
2) a test suite structure and test purposes (TSS&TP) document providing a natural-language
description of tests to be performed dependent on the PICS declaration;
3) an abstract test suite (ATS) providing test software (typically written in TTCN-3) to be
executed dependent on the PICS declaration.
— C-8: Regulations
The major topic is the provision of information on applicable regulations. Note that such information
is not usually provided in standards, whilst standards (e.g. Harmonized European Norms) are
referenced by regulation.
— C-9: Registries
The major topic is the provision of registration information, e.g. a registry of OSI layer port numbers
for a specific transport protocol, or a registry for globally unique ITS application identifiers (ITS-AID).
— C-10: Tutorials and guidelines
The major topic is the provision of tutorials on technical topics and guidelines on how to apply
standards; an example is this document.
— C-11: Reports
The major topic is the provision of non-normative information, and are largely different to tutorials
and guides, e.g. validation reports on conformance testing and security analysis (TVRA).
— C-12: Research
The major topic is the provision of results on scientific research related to potential future
standardization.
— C-13: Process
The major standardization topic is the provision of process specifications, e.g. business processes.
NOTE SDO deliverables can provide specifications related to various categories.
5 C-ITS services
5.1 General
C-ITS services are services from ITS service domains that are based on the concept of cooperation. The
[129]
concept of cooperation, i.e. C-ITS, is explained in the Brochure .
There exist approaches to identify ITS services and ITS use cases. However:
a) there is no consensus on a harmonized academic approach,
b) there are different regional needs and approaches, and
c) finally, it is proving difficult or even impossible to have any hierarchically structured
presentation at all.

---------------------- Page: 17 ----------------------
SIST-TP CEN ISO/TR 21186-1:2021
ISO/TR 21186-1:2021(E)
Three examples of approaches are presented below. This document does not use any one of these
approaches, but instead considers a "flat space" of C-ITS services.
The first example of such an approach is given by ISO 14813-1, presenting the following ITS service
domains:
— Traveller Information;
— Traffic Management and Operations;
— Vehicle Services;
— Freight Transport;
— Public Transport;
— Emergency Services;
— Transport-related Payment;
— Road transport related Personal Safety;
— Weather and Environmental Conditions Monitoring;
— Disaster Response Management and Coordination;
— National Security;
— ITS Data Management; and
— Performance Management.
A second international approach to identify ITS services was performed by the Harmonization Task
Group 7 with contributions from Australia, the European Union, and the United States of America. This
approach resulted in the "Harmonized Architecture Reference for Technical Standards" (HARTS) which
is presented at http:// htg7 .org/ . HARTS identified the following ITS service packages:
— Advanced Traveller Information Systems – Broadcast and Personalized;
— Connected Vehicle System Monitoring and Management;
— Core Authorization;
— Curve Speed Warning;
— Data Distribution;
— Eco-Approach and Departure at Signalized Intersections;
— Electric Charging Stations Management;
— Electronic Regulations;
— Emergency Vehicle Pre-emption;
— Freight Signal Priority;
— Intelligent Traffic Signal System;
— Intersection Safety Warning and Collision Avoidance;
— In-Vehicle Signage;
— Location and Time;
