Intelligent transport systems - Cooperative ITS - Dictionary of in-vehicle information (IVI) data structures (ISO/TS 19321:2015)
This TS specifies the In-Vehicle Information (IVI) data structures that are required
by different ITS services (e.g. In-vehicle Signage such as Contextual Speed, Road
Works Warning, Vehicle restrictions, lane restrictions, Road Hazard Warning, Rerouting)
to transmit information between ITS Stations (I2V).
The information will be specified in terms such as content / data elements and
data structures.
A general data structure that is future proof and extensible will be specified. A
split into sub-structures will be done.
The data structures are to be specified as communications agnostic. The TS needs
to identify groups of potential communication services (e.g. broadcast) such as
existing delivery mechanisms used by e.g. TPEG, DATEX II.
This Technical Specification will not provide the communication protocols.

Inteligentni transportni sistemi - Kooperativni sistem (ITS) - Podatkovni slovar informacijskih struktur v vozilih (IVI) (ISO/TS 19321:2015)
Ta tehnična specifikacija določa informacijske strukture v vozilih (IVI) (npr. znaki v vozilih, kot so kontekstualna hitrost, opozorilo o delu na cesti, omejitve vozila, omejitve voznega pasu, opozorilo o nevarnosti na cesti, preusmerjanje) za prenos informacij med postajami inteligentnih transportnih sistemov ITS (I2V). Informacije bodo določene v obliki vsebinskih/podatkovnih elementov in podatkovnih struktur. Določena bo splošna podatkovna struktura, ki bo dolgoročno vzdržna. Opravljena bo razdelitev v podstrukture. Podatkovne strukture bodo določene kot agnostična komunikacija. Tehnična specifikacija mora določati skupine potencialnih komunikacijskih storitev (npr. oddajanje), kot so obstoječi mehanizmi, ki jih uporabljata npr. podatkovni protokol TPEG, standard DATEX II. Ta tehnična specifikacija ne bo vsebovala komunikacijskih protokolov.

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

Introduction
In Cooperative-ITS (C-ITS), presenting information related to the traffic situation or regulation of a
road to the driver of a vehicle is an important component of road operations. The road operators are
responsible for road setup, operation, signage, and maintenance for traffic management and road safety,
and in some countries, also for the enforcement of road laws. For road operators, efficient transport of
vehicles on roadways ensures a safe and predictable trip for all road users. Road operators, together
with equipment manufacturers, be it that they are of vehicles or of roadside equipment, contribute to
how road information is properly presented to drivers.
So far, one defined C-ITS method for notifying road users of road and/or traffic situations and events is by
transmission of messages such as Cooperative Awareness Messages (CAM), Decentralized Environment
Notification Messages (DENM), or Basic Safety Messages (BSM).
This Technical Specification supports mandatory and advisory road signage such as contextual speeds
and road works warnings. In-vehicle information can be sent by an ITS-S and either corresponds to
physical road signs such as static or variable road signs or not correspond to physical road signs (a
virtual sign) or correspond to road works. IVI does not include identification of road events as already
provided by DENM.
This Technical Specification provides a toolbox of information elements for IVI. It can be used to fulfil
the requirements of the service provider considering the needs of receiving ITS-S. The container concept
provides a way for an ITS-S to manage the relevant IVI information, determine where the IVI is relevant,
and to provide details for the application of IVI. The description of data elements encompasses the data
syntax and semantics, i.e. a definition of data format and content, together with a description of how to
use those data elements.
This Technical Specification is of an enabling nature. It does not specify which information is necessary
for a certain service, but it supports those IVI information elements that can be necessary to be
transmitted to a receiving ITS-S to carry out a certain service. Usage of the IVI information elements
depends on the specific context and application of IVI for a specific service and usage is established as
mandatory or optional only for messaging purposes, not for application purposes. The IVI Structure is
intended to be profiled to fulfil the requirements of a specific service.
This Technical Specification refers to ISO/TS 14823 as one system of standardized codes for existing
road signs codes. Note that ISO/TS 14823 does not contain codes for specific national or regional signs
which are not commonly used. ISO/TS 14823 also does not represent a catalogue of road sign pictograms
for all applicable nations.

1 Scope
This Technical Specification specifies the in-vehicle information (IVI) data structures that are required by
different ITS services (for example, refer to ISO/TS 17425 and ISO/TS 17426) for exchanging information
between ITS Stations. A general, extensible data structure is specified (see Clause 5). This is split into
structures called containers to accommodate current-day information (see Clause 6). Transmitted
information includes IVI such as contextual speed, road works warnings, vehicle restrictions, lane
restrictions, road hazards warnings, location-based services, re-routing, etc. The information in the
containers is organized in sub-structures called data frames and data elements which are described in
terms of its content (see Clause 7) and its syntax (see Annex A).
The data structures are specified as communications agnostic. This Technical Specification does not
provide the communication protocols. This Technical Specification then provides scenarios for usage of
the data structure, e.g. in case of real time, short-range communications.

5 In-vehicle Information (IVI) data structure
5.1 Structural model
5.1.1 General model
The IVI Structure represents the Application Data Unit to be transmitted and received by an ITS-
Station (ITS-S). The IVI Structure shall comply with the syntax defined in Annex A as the data type
IviStructure. This means that it shall be composed of Containers defined in this Technical
Specification and follow the form depicted in Figure 1.
Figure 1 — IVI Structure
The IVI Structure is extensible and other containers can be added in the future.
The IVI Structure is intended to be encapsulated in a message with the appropriate ITS Common Header,
for example, the ItsPduHeader of ETSI/TS 102 894-2. The header structure and contents are out of the
scope of this Technical Specification
The IVI Structure shall contain a Management Container. The information in the IVI Management
Container is applicable to the entire IVI Structure. This Container is mandatory to be present and
provides a receiving ITS-S with enough information to handle the IVI Structure and decide on its further
processing.
The IVI Structure can contain one or more Location Container(s). The Location Container describes the
essential information for applications in the receiving ITS-S. Applications can use the location information
to understand how to apply information provided by IVI Application Containers. Location Containers
can carry information relevant for different IVI Application Containers or carry the same content, but
expressed in different forms (see 5.2). This enables a receiving ITS-S to choose the appropriate location
referencing system that the ITS-S supports.
The IVI Structure can contain one or more IVI Application Container(s). The IVI Application Container
provides IVI information for use by an application. Application information is self-contained and refers
to the location information for its spatial validity. Application information of the same type shall not
refer to overlapping Reference Zones. Each Application Container refers to zones defined in the Location
Container identified by their IDs for the following usage: 1) Detection Zone, 2) Relevance Zone, and
3) Driver Awareness Zone. An Application Container may optionally provide information about the
minimum awareness time, that is, the minimum time that the IVI should be available before the vehicle
enters the Relevance Zone. This MinimumAwarenessTime information can be used by the receiving
ITS-S to determine the appropriate Driver Awareness Zone.
5.1.2 Conceptual zones
When an ITS-S receives the IVI Structure, the ITS-S is able to interpret the application information in the
context of the appropriate location information. Principally, there are four conceptual zones:
1) Minimum Dissemination Area (MDA);
4 PROOF/ÉPREUVE © ISO 2014 – All rights reserved
---------------------- Page: 12 ----------------------
kSIST-TS FprCEN ISO/TS 19321:2015
ISO/TS 19321:2014(E)
2) Detection Zone;
3) Driver Awareness Zone (DAZ);
4) Relevance Zone (RZ).
The MDA refers to the minimum area where the IVI Structure is disseminated by an ITS-S based on
application requirements. The MDA is defined in the relevant application standards or specification(s)
and is therefore out of scope of this Technical Specification.
In some situations, a vehicle ITS-S must be able to detect whether or not it is approaching a Relevance
Zone at a certain minimum time before it enters the Relevance Zone. This is, for example, to guarantee
that the Relevance Zone is detected immediately at its entry (e.g. in case of a very small Relevance Zone)
or to guarantee that the Relevance Zone is correctly detected (in case it is near to other road segments,
e.g. parallel or on different altitude level). Therefore, a Detection Zone occurs in approach to a Relevance
Zone. If a receiving ITS-S moves through the Detection Zone, then the received IVI will be enabled for
further usage in the receiving ITS-S.
The IVI can be used to inform drivers about upcoming situations in the DAZ. The DAZ can be determined
by the receiving ITS-S because the DAZ can be based on the dynamic status of the receiving ITS-S and
can depend on the presence of other higher priority information to be presented. Alternatively, the DAZ
can be provided by the sending ITS-S for usage by the receiving ITS-S.
The final zone and the Relevance Zone covers the area where the IVI is applicable.
Examples of the Detection and Relevance Zones for the spatial validity of the IVI Structure are illustrated
in Figure 2. The Driver Awareness Zone (outside the scope of this Technical Specification) can be
physically overlapping with the Detection Zone (but is not necessarily equal in size).

Figure 2 — Spatial validity for IVI: Detection and Relevance Zones
The Location Container always contains a definition of one or more zones which can represent a Detection
Zone, a Relevance Zone, or both. In Figure 2, from left to right, the first zone represents a Detection Zone
and the second zone represents a Relevance Zone.
In Figure 3, from left to right, the first zone represents a Detection Zone. The second zone then represents
Relevance Zone 1, but this same zone also serves as a Detection Zone for Relevance Zone 2.

5.2 Location referencing
5.2.1 General
There are essentially two different ways of referencing road locations. It is called map-based location
referencing in this Technical Specification when referencing attributes of the road network itself. It is
called geographic location referencing in this Technical Specification when referencing a regular or
irregular division of space which exists independent of the representation of the road network.
5.2.2 Geographic positioning
Geographic location systems or coordinate systems are location maps composed of imaginary,
intersecting lines forming a grid. Coordinate values of the grid, expressed as numeric or alphanumeric
characters, are used to describe a position.
To translate position data expressed in longitude, latitude, and height to the corresponding real position
on earth or vice-versa, the earth-centred, earth-fixed, polar-coordinate geodetic datum WGS84(G1150)
according to NIMA TR8350.2 Version 3 shall be used. Alternatively, any earth-centred, earth-fixed polar
coordinate geodetic datum can be used as long as the maximum datum displacement relative to the
geodetic datum agreed on, or relative to WGS84(G1150) in case of no agreement, is acceptable to the
application.
NOTE A suggested tolerance of 0.3 meters in datum displacement (also called datum shift) is intended, for
example, to allow for using the International Terrestrial Reference Frame (ITRF) or the European Terrestrial
Reference Frame (ETRF) geodetic datum as alternative to the WGS84. Datum displacements are suggested to be
calculated according to the definitions in ASME Y14.5 – 2009.
An ITS-S sending an IVI Structure provides one or more Reference Point(s). The Reference Point can be
the reference for the description of a static zone or a dynamic (moving) zone. The zone can be described
by a polygonal line which delineates a segment or an area, or can be described by a distance value
indicating the extension of the relevance zone from the Reference Position and the heading relative to
the Reference Position.
The detection zone can optionally be provided as a polygonal line in approach to the Reference Position.
If the Reference Position is the position of a moving object, the polygonal line is represented by the last
positions of the path of the moving object (e.g. the trace of a roadworks vehicle).

kSIST-TS FprCEN ISO/TS 19321:2015
ISO/TS 19321:2014(E)
Determining the relevance of IVI is carried out by referencing the location of a receiving ITS-S relative
to a reference in a coordinate-based system.
As a vehicle progresses, its motion creates a series of points. The series, when assembled as a set, trace
the path of the vehicle. The path enables a receiving ITS-S to detect the applicability of a Relevance Zone
and the approach into a Relevance Zone.
5.2.3 Map-based location referencing
Determining the relevance of IVI can also be carried out by referencing the location of a receiving ITS-S
relative to a map reference (refer to ISO 17572-1). This can be a global map available in the receiving
ITS-S or it can be a local map distributed in the same dissemination area as IVI.
Map-based location referencing can be incorporated in future revisions of this Technical Specification.
6 IVI Containers
6.1 IVI Management Container
6.1.1 Definition
IVI Management Container contains information regarding the management of the IVI Structure which
supports the receiving ITS-S to deal with the lifecycle of the IVI. It includes information which allows
receiving ITS stations to identify further processing. Table 1 describes the contents for inclusion in the
IVI Management Container. The syntax is defined in Annex A as mandatory component of the data type
IviStructure.

6.1.2 Usage – IVI Management Container
The sending ITS-S shall include the component serviceProviderId, iviIdentificationNumber,
and can include the component timeStamp. The organization providing the IVI (e.g. the Service
Provider, as defined in ISO/TS 17427) should apply for a serviceProviderId.
NOTE 1 For detailed information, see http://www.itsstandards.eu/index.php?option=com_content&view=art
icle&id=186&Itemid=151.
The iviIdentificationNumber in the IVI Management Container is assigned by the Service Provider
and should be retained as long as the IVI Structure exists throughout its various updates and changes.
The component timeStamp should identify different versions of the IVI Structure due to updates
managed by the Service Provider. This component should be included if the sending ITS-S foresees to
send updates of the IVI Structure.
The sending ITS-S can include the components validFrom and validTo.
The sending ITS-S shall include the component iviStatus.
The optional components validFrom and validTo indicate the overall validity of the IVI Structure as
provided by the service provider. If validFrom is not present, the IVI Structure is valid when received.
If validTo is not present, no information about the expiration of the information is given.
A receiving ITS-S should check whether the status of the IVI Structure is any one of the following:
— new, that is, if the iviStatus is “new” and/or if the combination of serviceProviderId and
iviIdentificationNumber is different from other received messa
