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.

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

---------------------- Page: 8 ----------------------

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.

oSIST prEN 16157-4:2019
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
