Introduction
This Technical Specification 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 that interoperability, reduction of risk, reduction of the cost base and
promotion of open marketplace objectives are achieved that will lead to many social, economic and
community benefits as a result of 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 the 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 Technical Specification includes the framework and context for exchanges, the modelling approach, data
content, data structure and relationships and communications specification.
This Technical Specification supports a methodology that is extensible.
The fifth part of this Technical Specification deals with the one or more publication sub-model(s) within the
DATEX II model that support the exchange of measured and elaborated information. These publications are
intended to support the exchange of information from the organization having the measures and creating
elaborated data to other organizations providing ITS services or onward information exchange. It also includes
the exchange of static information about measurement sites.
The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning procedures, methods and/or
formats given in this document.
CEN takes no position concerning the evidence, validity and scope of patent rights.

1 Scope
This Technical Specification (CEN/TS 16157-5) 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, the data
content, the data structure and relationships and the communications specification.
This Technical Specification 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).
This Technical Specification 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 Technical Specification may be applicable for use by other actors.
This Technical Specification includes the following types of information 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 measured and elaborated data within the Datex II framework.
This is specified in three submodels, a DATEX II Measurement Site Table Publication submodel, a DATEX II
Measured Data Publication submodel and a DATEX II Elaborated Data Publication submodel.
1.1 Conformance
The platform independent sub-models defined by this Part specify a DATEX II Measurement Site
Table Publication, a DATEX II Measured Data Publication and a DATEX II Elaborated Data Publication except
for those elements that relate to location information which are specified in CEN/TS 16157-2. The DATEX II
platform independent data model these three publication sub-models are a part of which, corresponds to the
Level A model as defined in CEN/TS 16157-1.
Conformance with this Part shall require platform independent models from which platform specific models are
generated to comply with the UML modelling rules defined in CEN/TS 16157-1 and with the following
requirements of the sub-models which are expressed in this Part:
6

6 The Measurement Site Table Publication model
6.1 Overview of the Measurement Site Table Publication model
The Measurement Site Table Publication model comprises a top-level package,
“MeasurementSiteTablePublication” which utilizes some classes from the “ReusableClasses” package and the
“GroupOfLocations” package. This package is one of a number which are immediately subordinate to the
“PayloadPublication” package and hence forms the top of the hierarchy in the Measurement Site
Table Publication sub-model.
The “MeasurementSiteTablePublication” package models Measurement Site Tables comprising a number of
sets of data, each describing the location from where a stream of measured data may be derived. Each
location is known as a “measurement site” which can be a point, a linear road section or an area.
Each “MeasurementSiteTablePublication” instance shall contain one or more instances of a
“MeasurementSiteTable”, each table containing a number of “MeasurementSiteRecords”. Each
“MeasurementSiteRecord” shall be described by a location and specific characteristics.
Each “MeasurementSite” instance contains zero or more “Measurements” that have different characteristics
like e.g. traffic flow, speed,…
6.2 The “MeasurementSiteTablePublication” Package
6.2.1 Overview of the “MeasurementSiteTablePublication” Package
The “MeasurementSiteTablePublication” package shall comprise a sub-model for defining publishable
measurement site tables which comprise records defining the measurement sites (see Figure 1). Each
publication may contain one or more tables, allowing logical partitioning of measurement sites information as
deemed most appropriate for recipients of measured data information by the supplier (e.g. by road designation
or other geographic criteria or by type of measurement site, etc.)

6.2.2 Semantics of the “MeasurementSiteTablePublication” Package
6.2.2.1 “MeasurementSiteTablePublication” package semantics - general
The “MeasurementSiteTablePublication” class is a specific realizable case of a “PayloadPublication”. Each “MeasurementSiteTablePublication” may
contain any number of separate measurement site tables.
6.2.2.2 “MeasurementSiteTablePublication” Class
The “MeasurementSiteTablePublication” class is the base class for containing the published measurement site tables.
6.2.2.3 “HeaderInformation” Class
Each instance of a “MeasurementSiteTablePublication” shall have associated metadata contained in an instance of the “HeaderInformation” class which
allows the supplier of the “MeasurementSiteTablePublication” to specify how the recipient should treat the information contained in it. This class is already
defined in CEN/TS 16157-3.
6.2.2.4 “MeasurementSiteTable” Class
An identifiable versioned instance of the “MeasurementSiteTable” class shall contain any logical collection of “MeasurementSiteRecords”.
6.2.2.5 “MeasurementSiteRecord” Class
An identifiable versioned instance of the “MeasurementSiteRecord” class shall contain the characteristics information relating to a specific Measurement
Site.
Each record shall be located by a “GroupOfLocations” class. This class belongs to the “GroupOfLocations” package already described in CEN/TS 16157-2.
Each record shall have one indexed “MeasurementSpecificCharacteristics” sub-record for containing the characteristics of each individual measure. The
index provides the means for a measured value (in the MeasuredDataPublication) to be referenced to the relevant MeasurementSpecificCharacteristics at
the measurement site. Each measure can concern specific vehicles which are described by a “VehicleCharacteristics” class.
6.2.2.6 “MeasurementSpecificCharacteristics” Class
An instance of the “MeasurementSpecificCharacteristics” class contains characteristics which are specific to an individual measurement type (specified in a
known order) at the given measurement site.

6.2.2.7 “VehicleCharacteristics” Class
The characteristics of a vehicle, e.g. lorry of gross weight greater than 30 tonnes.
The “VehicleCharacteristics” class is defined in the “VehicleCharacteristics” package which is already described in CEN/TS 16157-3.
7 The Measured Data Publication model
7.1 Overview of the Measured Data Publication model
The Measured Data Publication model shall comprise a top-level package, “MeasuredDataPublication” and one sub-package “BasicData” from the
“ReusableClasses” package. The “MeasuredDataPublication” top-level package shall be one of a number which shall be immediately subordinate to the
“PayloadPublication” package and hence shall form the top of the hierarchy in the Measured Data Publication model.
7.2 The “MeasuredDataPublication” Package
7.2.1 Overview of the “MeasuredDataPublication” Package
The “MeasuredDataPublication” package shall comprise the sub-model for defining a publication containing one or more measurement data sets, each set
being composed of a number of measure values measured at a single measurement site.

7.2.2 Semantics of the “MeasuredDataPublication” Package
7.2.2.1 “MeasuredDataPublication” package semantics - general
The “MeasuredDataPublication” class shall be the only entry point of the package and shall be a specific realizable case of a “PayloadPublication”. Each
“MeasuredDataPublication” shall contain one or more measurement data sets, each set being measured at a single measurement site.
7.2.2.2 “MeasuredDataPublication” Class
The “MeasuredDataPublication” class shall be the base class for containing the published measured data.
7.2.2.3 “HeaderInformation” Class
Each instance of a “MeasuredDataPublication” shall have associated metadata contained in an instance of the “HeaderInformation” class which shall allow
the supplier of the publication to specify how the recipient of the “MeasuredDataPublication” should treat the information contained in it. This class is
already defined in CEN/TS 16157-3.
7.2.2.4 “SiteMeasurements” Class
The “SiteMeasurements” class shall contain a measurement data set derived from a specific measurement site.
Each measurement site, at a given time, has an indexed “MeasurementValue”. The “index” qualifier provides a reference to the specific
MeasurementCharacteristics that are relevant for the MeasuredValue at the referenced measurement site.
7.2.2.5 “MeasuredValue” Class
The “MeasuredValue” class contains optional characteristics for the specific measured value (indexed to correspond with the defined characteristics of the
measurement at the referenced measurement site) which override the static characteristics defined in the MeasurementSiteTable.
