Événements trafic en DATEX II v3.6

Traffic Events in DATEX II v3.6:

This dataset, published by the National Road Administration NRA (Administration des ponts et chaussées), provides up‑to‑date information on traffic events and changes affecting Luxembourg’s motorway and expressway network.

It contains information on accidents, roadworks, closures, obstructions and other disruptions. All events originate from the motorway Traffic Control Centre TCC (CITA - Contrôle et Information du Trafic sur les Autoroutes). This ensures a highly accurate and near real‑time information on current traffic conditions.

Typical information included in an event entry (example, not exhaustive):

· Type: MaintenanceWorks

· CreationTime : 2025-09-16T09:26:49+02:00

· probabilityOfOccurrence: certain

· safetyRelatedMessage : true

· numberOfLanesRestricted : 0

· numberOfOperationalLanes : 2

· generalPublicComment (lb) : A1 TG Montée Munsbach - Mesure de sécurité

· lengthAffected: 1297.0

· locationDescription (fr) : Section courante

· carriageway : mainCarriageway

· roadDestination: Autoroute de Tréves, vers Gasperich

· roadName: A1

· gmlLineString – posList: 49.63684 6.242621 49.636883 6.241793 … etc.

The data is automatically generated and made available in XML format following the DATEX II exchange standard, specifically the European Norm “EN 16157 – Part 3: Situation Publication (2018)”. The dataset classifies events by the predefined main event categories in DATEX II, which means:

· Roadworks,

· Accidents,

· Obstructions,

· Conditions

This standardized structure enables seamless integration into traffic information and traffic management systems, research workflows, and mobile applications of service providers or others. Possible Use cases could include:

· Real‑time traffic maps

· Congestion and incident warning systems

· Routing optimisation

· Mobility and navigation apps

· Traffic research models

· Long‑term traffic and infrastructure analysis

Legal Basis (1/2) – ITS / RTTI

The data objects defined within a SituationRecord cover the related data types defined in European Commission Delegated Regulation (EU) 2022/670 of 2 February 2022 supplementing Directive 2010/40/EU of the European Parliament and of the Council with regard to the provision of EU-wide real-time traffic information (RTTI) services (Text with EEA relevance). The relevant definitions are listed in Annex I:

State of the network (Annex I N°4, N°5)

· crucial: road works | road closures | lane closures | traffic management measures

· other: accidents | incidents | poor road conditions |weather conditions affecting road surface and visibility

Legal Basis (2/2) – ITS / SRTI

The SituationRecord objects support the European Commission Delegated Regulation (EU) No 886/2013 of 15 May 2013 supplementing Directive 2010/40/EU of the European Parliament and of the Council with regard to data and procedures for the provision, where possible, of road safety-related minimum universal traffic information (SRTI) free of charge to users Text with EEA relevance.

The combination of highly accurate, validated traffic information and the rapid publication of DATEX II messages ensures the timely, reliable, and safety-critical dissemination of traffic events, making the provided data messages a meaningful contribution to the provision of SRTI information.

File Format

The DATEX II structure and its validation rules for XML (Extensible Markup Language) are defined and provided through a dedicated XSD (XML Schema Definition) schema file. The corresponding DATEX II messages are available in a referenced XML file, which can be downloaded from this page via the ‘SituationRecord – Data’ link in the ‘Fichiers’ tab.

Data Accuracy & Temporal Validity

The SituationRecord represents an almost real‑time traffic‑related state associated with a specific timestamp, as encoded in each entry of the DATEX II XML data file. All information published in this feed is pre‑validated by motorway TCC (traffic control center) operators, ensuring a high level of accuracy and reliability.

The TCC operators typically process and update motorway traffic information in less than five minutes. The XML file is refreshed automatically every minute.

According to the DATEX II standard, events are not explicitly marked as terminated. Instead, they are automatically removed from the publication once they no longer reflect the operational traffic situation. This guarantees that the data feed contains only active and up‑to‑date traffic situations.

Revision Cycle

There is no fixed periodic revision cycle for the data model. Most use cases supported by the SituationRecord are already fully covered by the existing implementation. Future adjustments or extensions of the model are driven by the evolution of the DATEX II (EN 16157 – Part 3: Situation Publication (2018)) standard and by newly emerging use cases that require additional modelling support.

Temporal Coverage

The current start date of the temporal coverage reflects the official publication date as of 02 February 2026, DATEX II Version 3.6. Since SituationRecords are continuously updated and event‑driven information, no temporal coverage “end date” can be defined.
