ISO/TS 19321:2015 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.

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

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.

Intelligent transport systems — Cooperative ITS —
Dictionary of in-vehicle information (IVI) data structures
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
