TN-ITS innovation platform
TN-ITS is concerned with information exchange on changes in static road attributes. Road safety and efficiency require highly updated digital maps for ITS, but map providers struggle to keep these elements current. The solution is to retrieve the information on changes from the road authorities. As regulators of these changes, e.g., speed limits, they are the most immediate and reliable source for such information.
Vision:
– TN-ITS provides the updates on trusted, authoritative and regulatory road data to support ITS applications such as Safety, Automation and Efficient Mobility.
– TN-ITS is a a mandatory exchange format in the EU Mobility Data Space.
Mission:
– Facilitate and foster the exchange of ITS-related spatial road data between road authorities as trusted data providers, and data users as map providers and other parties.
– Bringing fresher digital map data to intelligent transport services, including authoritative and regulatory data and information.
GOALS
- To supply fresh, quality, accurate, and trusted digital maps to leading map and service providers. These maps represent the base for any of the advanced traffic applications that you experience e.g. in your car, or on your phone.
- Provide information exchange on modifications in static road attributes. The focus is on general on-road features based on regulations but may extend to other road and transport-related aspects.
- Serve as a joined innovation platform at the European level involving public administration to ensure road safety through accurate information shared by digital maps.

TN-ITS is the Transport Network ITS Spatial Data Deployment ERTICO innovation Platform founded on 5 June 2013 at an inaugural General Assembly held in Dublin (Ireland) during the ITS European Congress.
The concept of TN-ITS evolved from work in the EU funded project PReVENT/MAPS&ADAS (February 2004 – January 2007) on safety-related road attributes for ADAS applications, and especially from the EU-funded project ROSATTE (January 2008 – June 2010), which aimed at establishing an efficient and quality-ensured supply chain for information on safety-related road attributes, from public authorities to commercial map providers and other road data users, with a focus on changes in the concerned attributes rather than full data sets. The rationale behind TN-ITS is that for information on changes in static road attributes, the public authorities, who create the changes, are potentially the most efficient and immediate source. If processes and procedures are organised well, they can be a highly trusted source, while the information provided will reflect concise unambiguous spatial update reports that do not need substantial processing and interpretation.
The TN-ITS exchange framework originated from the ROSATTE project deliverable D3.1 “Specification of data exchange methods”. The core part of this document provides the specification of a mechanism for data exchange of road safety information, which consists of:
- a conceptual specification of the data content, using UML.
- a physical exchange format (structure and coding using GML schema) to specify a coding for the various types of data under the conceptual model
- a service specification, using UML class diagrams to facilitate the actual data flow between the various actors within ROSATTE.

The data-chain mechanism
TN-ITS enables a data chain for timely provision of information on changes in road attributes and other elements of the physical road network infrastructure for inclusion in digital maps for ITS applications, including public transport elements and geometry.
The Swedish TN-ITS service is available from the Swedish Transport Administration. It is operational since 2014 and publishes daily changes in speed limits, road information and road restrictions for the full country covering all road types. The service shares linear and point features reflecting road information and traffic signs. It supports different types of location referencing methods to maximize the re-use of the information (OpenLR, GML, and INSPIRE linear referencing).
The point of contact is Ms. Miho Ishii (geografisk.information @trafikverket.se).
For access to the service, please read Service Description found on this page: Nedladdningstjänst, daglig fölrändringsinformation av vägdata/TN-ITS.
The Norwegian TN-ITS service is available from the Norwegian Public Road Administration. It is operational since 2015 and publishes changes of speed limits, road info, road restriction and warnings on a daily basis. Changes for the full country covering all road types are made available. The service shares linear and point features reflecting road information and traffic signs. It supports different types of location referencing methods to maximize the re-use of the information (OpenLR, GML, and INSPIRE linear referencing).

The Finish TN-ITS service is available from the Finish Transport Administration. It is operational since 2016 and publishes batch updates of changes of speed limits covering all roads for the entire Finish territory. The service shares linear and point features reflecting road information and traffic signs. It supports different types of location referencing methods to maximize the re-use of the information (OpenLR, GML, and INSPIRE linear referencing).

The Flemish TN-ITS service is available via the Agentschap Wegen en Verkeer as an operational service. The service mainly publishes changes of speed limits and traffic restrictions for roads in the Flemish region, but also warning signs, supporting both point and linear features. Different types of location referencing methods are available to maximize the re-use of the information (OpenLR, GML). Flanders has implemented the CEN TS 17268 in the 3rd quarter of 2021.
The point of contact is Ms. Nele Dedene (nele.dedene@mow.vlaanderen.be).

The UK TN-ITS service is available from the Department for Transport (DfT). The pilot service has been available since 2017 and has demonstrated the ability to publish batches of changes in speed limits, road information and road restrictions impacting on all road classifications for limited trial areas of the UK. The service shares linear and point features reflecting speed limits and other road restrictions respectively. It supports different types of location referencing methods to maximize the re-use of the information (GML and INSPIRE linear referencing). DfT is a partner in the TN-ITS GO project to advance TN-ITS services in Europe (2018-2021).

The IGN proposal for the road data provision pilot is based to the perspective to get the regular INSPIRE services for roads. Since 2016, a daily updating geospatial data service provides a digital cartographic service including local to national road data. The content will be enhanced in the 2018 to 2020 period with vehicle restrictions for width and weight, park access and speed limits. The pilot was published in 2017 for several months. He will be rebuild in the 1st semester 2018 with a better informatics, an extended set of attributes and an area extended to the whole Hauts-de-France region.
The point of contact is Mr Alain Chaumet ( alain.chaumet@ign.fr).
The Hungarian TN-ITS service is available from the Hungarian Public Road Ltd. It is operational since 2018 and publishes changes of speed limits and road restriction on a monthly basis. Changes for the country covering all main roads and highways are made available. The service shares linear and point features reflecting road information and traffic signs. It supports GML location referencing method at the pilot phase which will be expanded whit a few others in order to maximize the re-use of the information.
