Intelligent transport systems - DATEX II data exchange specifications for traffic management and information - Part 4: VMS publication

This European Standard (EN 16157 series) specifies and defines component facets supporting the exchange and shared use of data and information in the field of traffic and travel.
The component facets include the framework and context for exchanges, the modelling approach, data content, data structure and relationships.
This European Standard is applicable to:
-   Traffic and travel information which is of relevance to road networks (non-urban and urban),
-   Public transport information that is of direct relevance to the use of a road network (e.g. road link via train or ferry service),
-   Traffic and travel information in the case of Cooperative intelligent transport systems (C-ITS).
This European Standard establishes specifications for data exchange between any two instances of the following actors:
-   Traffic Information Centres (TICs),
-   Traffic Control Centres (TCCs),
-   Service Providers (SPs),
Use of this European Standard may be applicable for use by other actors.
This European Standard series covers, at least, the following types of informational content:
-   Road traffic event information – planned and unplanned occurrences both on the road network and in the surrounding environment,
-   Operator initiated actions,
-   Road traffic measurement data, status data, and travel time data,
-   Travel information relevant to road users, including weather and environmental information,
-   Road traffic management information and instructions relating to use of the road network.
This part of the CEN/TS 16157 series specifies the informational structures, relationships, roles, attributes and associated data types required for publishing variable message sign information within the Datex II framework. This is specified in two publications, a DATEX II VMS Table Publication sub-model and a VMS Publication sub-model, which are part of the DATEX II platform independent model, but this part excludes those elements that relate to:
-   location information which are specified in EN 16157-2,
-   common information elements, which are specified in EN 16157-7,
-   situation information which are specified in EN 16157-3.
The VMS Table Publication supports the occasional exchange of tables containing generally static reference information about deployed VMS which enable subsequent efficient references to be made to pre-defined static information relating to those VMS. The VMS Publication supports the exchange of the graphic and textual content of one or several VMS plus any status information on device configuration that aid the comprehension of the informational content. This content is potentially subject to rapid change.
These publications are not intended to support the control or configuration of VMS equipment. Each is part of the DATEX II platform independent model.

Systèmes de transport intelligents - Spécifications Datex II d'échange de données pour la gestion du trafic et de l'information routière - Partie 4 : Publication de messages PMV

Le présent document est la quatrième partie de la Norme européenne Datex II qui porte sur les sous-modèles de publication au sein du modèle Datex II permettant l’échange d’informations destinées aux panneaux à message variable.
Ces publications visent à permettre l’échange d’états et de contenus informationnels concernant les PMV entre l’organisation contrôlant les PMV et les autres organisations fournissant des services ITS ou un échange d’informations ultérieur. Elles n’ont pas pour objectif de permettre le contrôle ou la configuration des équipements PMV.
Cela est spécifié dans deux sous-modèles, un sous-modèle de publication de tables de PMV Datex II et un sous-modèle de publication PMV Datex II.

European foreword
This document (EN 16157-4:2021) has been prepared by Technical Committee CEN/TC 278 “Intelligent
transport systems”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2021, and conflicting national standards shall
be withdrawn at the latest by September 2021.
This document supersedes CEN/TS 16157-4:2014.
The major differences introduced in the new edition of this document are:
— renaming of some classes (e.g. currently renamed Vms, VmsController, VmsControllerStatus,
VmsStatus) to improve the understanding and the usage of the modelled information;
— merging of VMS characteristics and VMS configuration in a same model to address static and dynamic
configuration as well as VmsMessage package restructured enhancing the model flexibility for
inclusion of dynamic configured VMS, e.g. “Full-Matrix” VMS;
— Compliance to ISO 14823:2017 - Intelligent transport systems – Graphic data dictionary, for
description of Pictogram graphical information;
— correction of several bugs.
This document - EN 16157-4 - is the fourth part of a multi-part standard under the general title Intelligent
transport systems - DATEX II data exchange specifications for traffic management and information. A list of
all parts in the CEN 16157 series can be found on the CEN website.

Introduction
This document defines a common set of data exchange specifications to support the vision of a seamless
interoperable exchange of traffic and travel information across boundaries, including national, urban,
interurban, road administrations, infrastructure providers and service providers. Standardization in this
context is a vital constituent to ensure interoperability, reduction of risk, reduction of the cost base,
promotion of open marketplaces and many social, economic and community benefits to be gained from
more informed travellers, network managers and transport operators.
Delivering European Transport Policy in line with the White Paper issued by the European Commission
requires co-ordination of traffic management and development of seamless pan European services. With
the aim to support sustainable mobility in Europe, the European Commission has been supporting the
development of information exchange mainly between the actors of the road traffic management domain
for a number of years. In the road sector, DATEX II has been long in fruition, with the European
Commission being fundamental to its development through an initial contract and subsequent co-funding
through the Euro-Regional projects. With the standardization of DATEX II, there is a real basis for
common exchange between the actors of the traffic and travel information sector.
This document includes the framework and context for exchanges, the modelling approach, data content,
data structure and relationships. This European Standard supports a methodology that is extensible.
This document specifies the informational structures, relationships, roles, attributes and associated data
types required for publishing variable message sign information within the DATEX II framework. It
specifies the structures and definitions of information that can be exchanged to convey details of the
messages displayed on variable message signs, the current configuration, characteristics and status of the
variable message signs that are currently deployed on the road network.
This is specified in two publications, a DATEX II VMS Table Publication sub-model and a VMS Publication
sub-model, which are part of the DATEX II platform independent model, but this document excludes those
elements that relate to:
— location information which are specified in EN 16157-2
— common information elements, which are specified in EN 16157-7
— situation information which are specified in EN 16157-3.
The VMS Table Publication supports the occasional exchange of tables containing generally static
reference information about deployed VMS which enable subsequent efficient references to be made to
pre-defined static information relating to those VMS.
The VMS Publication supports the exchange of the graphic and textual content of one or several VMS plus
any status information on device configuration that aid the comprehension of the informational content.
This content is potentially subject to rapid change.
These publications are not intended to support the control or configuration of VMS equipment. Each is
part of the DATEX II platform independent model.

1 Scope
This document is the fourth part of the DATEX II European Standard which deals with the publication
sub-models within the DATEX II model that support the exchange of variable message sign information.
These publications are intended to support the exchange of status and informational content concerning
VMS from the organization controlling the VMS to other organisations providing ITS services or onward
information exchange. It is not intended to support the control or configuration of VMS equipment.
This is specified in two sub-models, a DATEX II VMS Table Publication sub-model and a DATEX II VMS
Publication sub-model.

Introduction
This European Standard defines a common set of data exchange specifications to support the vision of a
seamless interoperable exchange of traffic and travel information across boundaries, including national,
urban, interurban, road administrations, infrastructure providers and service providers.
Standardization in this context is a vital constituent to ensure interoperability, reduction of risk,
reduction of the cost base, promotion of open marketplaces and many social, economic and community
benefits to be gained from more informed travellers, network managers and transport operators.
Delivering European Transport Policy in line with the White Paper issued by the European Commission
requires co-ordination of traffic management and development of seamless pan European services.
With the aim to support sustainable mobility in Europe, the European Commission has been supporting
the development of information exchange mainly between the actors of the road traffic management
domain for a number of years. In the road sector, DATEX II has been long in fruition, with the European
Commission being fundamental to its development through an initial contract and subsequent co-
funding through the Euro-Regional projects. With this standardization of DATEX II, there is a real basis
for common exchange between the actors of the traffic and travel information sector.
This European Standard includes the framework and context for exchanges, the modelling approach,
data content, data structure and relationships.
This European Standard supports a methodology that is extensible.
The fourth part of this European Standard deals with the publication of variable message sign (VMS)
information. It specifies the structures and definitions of information that can be exchanged to convey
details of the messages displayed on variable message signs, and the current configuration and
characteristics and status of the variable message signs that are currently deployed on the road
network.

1 Scope
This European Standard (EN 16157 series) specifies and defines component facets supporting the
exchange and shared use of data and information in the field of traffic and travel.
The component facets include the framework and context for exchanges, the modelling approach, data
content, data structure and relationships.
This European Standard is applicable to:
— Traffic and travel information which is of relevance to road networks (non-urban and urban),
— Public transport information that is of direct relevance to the use of a road network (e.g. road link
via train or ferry service),
— Traffic and travel information in the case of Cooperative intelligent transport systems (C-ITS).
This European Standard establishes specifications for data exchange between any two instances of the
following actors:
— Traffic Information Centres (TICs),
— Traffic Control Centres (TCCs),
— Service Providers (SPs),
Use of this European Standard may be applicable for use by other actors.
This European Standard series covers, at least, the following types of informational content:
— Road traffic event information – planned and unplanned occurrences both on the road network and
in the surrounding environment,
— Operator initiated actions,
— Road traffic measurement data, status data, and travel time data,
— Travel information relevant to road users, including weather and environmental information,
— Road traffic management information and instructions relating to use of the road network.
This part of the CEN/TS 16157 series specifies the informational structures, relationships, roles,
attributes and associated data types required for publishing variable message sign information within
the Datex II framework. This is specified in two publications, a DATEX II VMS Table Publication sub-
model and a VMS Publication sub-model, which are part of the DATEX II platform independent model,
but this part excludes those elements that relate to:
— location information which are specified in EN 16157-2,
— common information elements, which are specified in EN 16157-7,
— situation information which are specified in EN 16157-3.
The VMS Table Publication supports the occasional exchange of tables containing generally static
reference information about deployed VMS which enable subsequent efficient references to be made to
pre-defined static information relating to those VMS. The VMS Publication supports the exchange of the
graphic and textual content of one or several VMS plus any status information on device configuration

that aid the comprehension of the informational content. This content is potentially subject to rapid
change.
These publications are not intended to support the control or configuration of VMS equipment. Each is
part of the DATEX II platform independent model.

7 The VMS model
7.1 Overview of the VMS model
The VMS model shall be immediately subordinate to the “PayloadPublication” package and shall
comprise the packages used in the VMS Table Publication and VMS Publication and the Classes and
Enumerations specific for these Payload Publication.
Some of the packages and individual classes used within the “VMS Model” package reside in the
“D2Namespace” namespaces “Common”, “Location”, “SituationPublication” and because they can be
used in different places within this package or by other packages either now or in the future. The named
namespaces (D2Namespace) shall be a container for a number of packages and individual reusable
classes. Those packages and classes which are contained in the named namespaces are identified in the
following clauses. The use of individual classes from the named namespace is only described in detail if
their use in the “VMS Publication” affects their semantics.
The classes, attributes, data types and enumerations that are specific to this document are defined in
the normative Annex A.
The XML subschema corresponding to this document is provided in the normative Annex B.
7.2 The VMS Table Publication model
The VMS Table Publication model shall comprise a top-level package, “VmsTablePublication” which
utilizes some classes from the “Classes” package.
The “VmsTablePublication” package shall model the normally static characteristics of VMS units and
their controlled VMS.
Each “VmsTablePublication” instance shall contain one or more instances of a “VmsUnitTable”, each
table containing a number of “VmsUnits” which relate to deployed VMS units. Each “VmsUnit” shall
contain one or more “Vmss” each of which relates to a specific VMS that is controlled by the VMS unit.
Although the characteristics of VMSs and VMS units modelled in this publication are normally static,
sometimes these characteristics change over a period of time. For instance, changes do occur in the
location of VMSs when they are of a mobile type or in the number of lines of text if the sign supports
variable font sizes. In these cases, some of the characteristics defined in this publication may be
overridden by more up-to-date information promulgated in a “VmsPublication”. VMS characteristics
information provided in a “VmsPublication” shall always override any characteristics information
provided in the records of a “VmsTablePublication”.
7.3 The VMS Table Publication package
7.3.1 Overview of the VMS Table Publication package
The “VmsTablePublication” package shall comprise a sub-model for defining information describing the
normally static characteristics of VMS units and their VMS (see Figure 1). Each publication may contain
one or more tables, allowing logical partitioning of VMS static information as deemed most appropriate
for recipients of VMS information by the supplier (e.g. by road designation or other geographic criteria
or by type of VMS equipment etc.).
The VMS Table class diagram is shown in Figure 1.

7.3.2 Semantics of the VMS Table Publication package
7.3.2.1 “VmsTablePublication” package semantics - general
The “VmsTablePublication” class shall be a specific realizable class as specialization of
“PayloadPublication”. Each “VmsTablePublication” may contain any number of separate VMS Unit
Tables.
The information in the “VmsTablePublication” shall relate to the VMS units and their controlled VMSs
currently deployed on the road, and shall contain the normally static characteristics of those devices at
a specified point in time. However, the characteristics of any VMS given in the “VmsTablePublication”
shall be overridden by any corresponding characteristics that are given in a “VmsPublication” for the
same VMS.

prEN 16157-4:2019 (E)
Some of the individual classes used within the “VmsTablePublication” package, principally those for
modelling the characteristics of a VMS, also reside in the “VmsRelated” package which is within the
“Classes” package as they are also used in the “VmsPublication” package”.
7.3.2.2 “VmsTablePublication” Class
The “VmsTablePublication” class shall be the base class for containing the published VMS unit tables.
7.3.2.3 “HeaderInformation” Class
Each instance of a “VmsTablePublication” shall have associated metadata contained in an instance of
the “HeaderInformation” class which shall allow the supplier of the “VmsTablePublication” to specify
how the recipient should treat the information contained in it. For “HeaderInformation” class refer to
EN 16157-7.
7.3.2.4 “VmsUnitTable” Class
An identifiable versioned instance of the “VmsUnitTable” class shall contain any logical collection of
“VmsUnitRecords”. A supplier may choose to provide a textual identifier for a particular
“VmsUnitTable” to clarify the logical collection of “VmsUnit”.
7.3.2.5 “VmsUnit” Class
An identifiable versioned instance of the “VmsUnit” class shall contain the characteristics information
relating to a specific VMS unit. Each record shall have one or more indexed “Vms” sub-records for
containing the characteristics of the individual VMSs that are controlled by the VMS unit. The
“vmsIndex” qualifier allows the specific VMS that is controlled by the VMS unit to be specified.
7.3.2.6 “Vms” Class
An instance of the “Vms” class shall allow a supplier to identify the normally static characteristics of a
VMS. The location of the VMS may be specified via the composition to “vmsLocation” and any location
that is managed by the VMS such as a car park or junction may be specified via composition with the
“VmsManagedLogicalLocation” class.
The LocationReference class sha
