Intelligent transport systems - DATEX II data exchange specifications for traffic management and information - Part 2: Location referencing
This European Standard series (EN 16157) 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 series 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 series 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 series 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 EN 16157 series specifies the informational structures, relationships, roles, attributes and associated data types, for the implementation of the location referencing systems used in association with the different publications defined in the Datex II framework. It also defines a DATEX II publication for exchanging predefined locations. This is part of the DATEX II platform independent data model.

Figure 4 — The “AreaLocation” class model 7.1.5.2 Semantics An area (class “AreaLocation”) can be either a geographic or a geometric two-dimensioned feature. It may be qualified by height information to provide additional geospatial discrimination (e.g. for snow in an area but only above a certain height). It shall be referenced using one of the following five methods without being exclusive: — the Alert-C location referencing method (see 7.2.1 package “AlertCArea”); — the TPEG-Loc location referencing method (see 7.7.1 package “TpegAreaLocation”); — the OpenLR™ location referencing method (see 7.8.3 package “OpenlrArea”); — as a named area (see 7.9 package “NamedArea”); — as an area defined as a multipolygon (see 7.3 package “Gml”). 7.2 The package “AlertC” 7.2.1 The package “AlertCArea” 7.2.1.1 The class model The package “AlertCArea” supplies classes and attributes to the definition of an area-typed location using a pre-defined ALERT-C area location. It is pictured including the relationships between the classes in Figure 5. SIST EN 16157-2:2019
Figure 5 — The “AlertCArea” package class model 7.2.1.2 Semantics An ALERT-C area (class “AlertCArea”) represents an area defined by reference to an area already defined in a pre-defined ALERT-C location table. 7.2.2 The package “AlertCLinearByCode” 7.2.2.1 The class model The package “AlertCLinearByCode” supplies classes and attributes to the definition of a linear location using a pre-defined ALERT-C linear location. It is pictured including the relationships between the classes in Figure 6. SIST EN 16157-2:2019
Figure 6 — The “AlertCLinearByCode” package class model 7.2.2.2 Semantics An ALERT-C linear location reference by code presents a linear section along a road defined by an ALERT-C code i.e. a tabular reference of linear location in an ALERT-C location table (class “AlertCLinearByCode”). It shall have an associated direction of traffic flow representing the direction of traffic flow along the road to which the information relates (class “AlertCDirection”). The ALERT-C linear location reference is given an ALERT-C direction using a set of predefined coded values. The attribute “alertCDirectionCoded” is used to define which offset type (i.e. negative or positive) is used to navigate in the ALERT-C location table. The attribute “alertCAffectedDirection” specifies the driving direction(s) affected by the traffic object. A name may also be added to complete the direction definition. 7.2.3 The package “AlertCMethod2Linear” 7.2.3.1 The class model The package “AlertCMethod2Linear” supplies classes and attributes to the definition of a linear location using the method 2 as explained in EN ISO 14819-3:2013, Annex C. It is pictured including the relationships between the classes in Figure 7. SIST EN 16157-2:2019
Figure 7 — The “AlertCMethod2Linear” package class model 7.2.3.2 Semantics An ALERT-C linear location reference using method 2 (class “AlertCMethod2Linear”) represents a linear section along a road between two points, primary and secondary, which are pre-defined in an ALERT-C location table. Direction is from the secondary point (class “AlertCMethod2SecondaryPointLocation”) to the primary point (class “AlertCMethod2PrimaryPointLocation”), i.e. the secondary point is first met before the primary point when the road section is travelled in the location direction. It shall have an associated direction of traffic flow representing the direction of traffic flow along the road to which the information relates (class “AlertCDirection”). The ALERT-C linear location reference is given an ALERT-C direction using a set of predefined coded values. The attribute “alertCDirectionCoded” is used to define which offset type (i.e. negative or positive) is used to navigate in the ALERT-C location table. The attribute “alertCAffectedDirection” specifies the driving direction(s) affected by the traffic object. In case of a ring road, the “alertCDirectionCoded” attribute is used to remove the ambiguity how to reach the primary point from the secondary point. A name may also be added to complete the direction definition. SIST EN 16157-2:2019
Figure 8 — The “AlertCMethod2Point” package class model 7.2.4.2 Semantics An ALERT-C point using method 2 (class “AlertCMethod2Point”) represents a single point on the road network defined by reference to a point in a pre-defined ALERT-C location table (class “AlertCMethod2PrimaryPointLocation”). This point is called primary point. It also has an associated direction of traffic flow representing the direction of traffic flow along the road to which the information relates (class “AlertCDirection”). The ALERT-C point location is given an ALERT-C direction using a set of predefined coded values. The attribute “alertCDirectionCoded” is used to define which offset type (i.e. negative or positive) is used to navigate in the ALERT-C location table. The attribute “alertCAffectedDirection” specifies the driving direction(s) affected by the traffic object. A name may also be added to complete the direction definition. SIST EN 16157-2:2019
Figure 9 — The “AlertCMethod4Linear” package class model 7.2.5.2 Semantics An ALERT-C linear location reference using method 4 (class “AlertCMethod4Linear”) represents a linear section along a road between two points, primary and secondary, which are pre-defined in an ALERT-C location table, accompanied by distances. The distance is defined as being the non-negative distance in metres between the ALERT-C point and the actual referenced point (class “OffsetDistance”). Direction is from the secondary point (class “AlertCMethod2SecondaryPointLocation”) to the primary point (class “AlertCMethod2PrimaryPointLocation”), i.e. the secondary point is first met before the primary point when the road section is travelled in the location direction. It shall have an associated direction of traffic flow representing the direction of traffic flow along the road to which the information relates (class “AlertCDirection”). SIST EN 16157-2:2019
Figure 10 — The “AlertCMethod4Point” package class model 7.2.6.2 Semantics An ALERT-C point using method 4 (class “AlertCMethod4Point”) represents a single point on the road network as defined by reference to a point in a pre-defined ALERT-C location table (class “AlertCMethod
