TN-ITS Marks a Year of Progress at the 4th Quarterly Partner Meeting & General Assembly

In December 2025, the TN-ITS members gathered in Brussels for its 4th Quarterly Partner Meeting and General Assembly, hosted at the ERTICO offices. Across two days, partners combined hands-on discussions with strategic reflections, taking stock of an eventful year and reinforcing the collaborative spirit that continues to drive TN-ITS forward. 

This year’s meetings struck a strong balance between technical progress, deployment realities and community-building, reflecting the platform’s evolution.

2025 in focus: 4 achievements that shaped the year 

1) A decisive step toward European standardisation: CEN process launched for DATEX II Part 14 (TN-ITS)
One of the most significant milestones of 2025 was the launch of the CEN standardisation process for DATEX II Part 14 (TN-ITS). The initiative was endorsed by more than 10 Member States, exceeding the 5 votes required – a strong signal of momentum toward a unified European framework for road and traffic data exchange. 

Positioning TN-ITS as Part 14 of the CEN 16157 DATEX II series strengthens interoperability and reduces fragmentation by providing a single reference architecture that supports National Access Points and the implementation of EU ITS and RTTI regulations. In practical terms, it brings stakeholders closer to one coherent toolbox covering both what is happening on the road (dynamic and regulatory traffic information through DATEX II) and what the road is supposed to be (authoritative static road attributes such as speed limits and traffic signs via TN-ITS). 

This development is further reinforced by the cooperation agreement between the DATEX II community and the ERTICO-led TN-ITS innovation platform, supporting joint governance and a consistent evolution of the harmonised framework.

2) Turning partnership into deployment: advancing an AI-supported tool for TN-ITS updates
Ahead of the Quarterly Partner Meeting, the TN-ITS Task Group held a dedicated workshop on an AI-supported tool aimed at streamlining the creation and publication of TN-ITS map update messages, especially for “level-zero” users, meaning organisations that currently have no tools to generate TN-ITS updates. 

Discussions focused on defining the Minimum Viable Product (MVP) for a centrally hosted and user-friendly application. Key requirements included capturing geometry without manual coordinate entry, supporting different operator modes (drawing geometry or inheriting it from an underlying map), and performing syntax-based validation of generated messages. 

Partners also explored practical constraints such as map backdrop selection, intellectual property considerations and the potential use of curated datasets. Importantly, the workshop also positioned this tool within a broader ecosystem – linking future interoperability and funding opportunities with initiatives such as NAPCORE, TISGRADE and the emerging CCAM dataspace/EDIC context. 

3) Strengthening alignment through key industry platforms: TISA and OADF
TN-ITS also continued to reinforce alignment across the mobility data landscape through active contributions to leading industry platforms. 

Through sustained engagement in TISA, including the 5★ and Location Referencing task forces, stakeholders are contributing to improved consistency between authoritative road data exchange, service-oriented traffic information and map update ecosystems. Close cooperation with the ERTICO innovation platforms SENSORIS and ADASIS further supports consistency between in-vehicle data flows, map update chains and road authority information, reinforcing a common technical direction complementary to initiatives such as NAPCORE. 

In parallel, TN-ITS’ participation in the Open AutoDrive Forum (OADF) – including hosting the 21st OADF meeting – expanded this dialogue beyond Europe, connecting TN-ITS developments with global communities working on automated and connected driving data frameworks. 

4) Exploring Cycling Infrastructure Data: from specifications to real-world use cases
The 4th Quarterly Partner Meeting also highlighted exploratory work on Cycling Infrastructure Data, building on TN-ITS activities throughout 2025 to assess how its specifications and data-sharing approaches could support cycling and other active mobility modes. Contributions to stakeholder exchanges and to the NAPCORE cycling ambassadors led to recommendations addressed to the European Commission and helped frame reflections around future initiatives. 

These efforts confirmed the potential for TN-ITS to support standardised, authoritative exchange of cycling infrastructure and regulatory data, aligned with DATEX II and existing TN-ITS models. By extending current specifications, TN-ITS could contribute to more consistent digital representations of cycling networks, supporting urban mobility planning, safety policies and the broader transition toward multimodal and sustainable transport systems across Europe.

Leadership continuity and community recognition 

Beyond progress milestones, the General Assembly also reaffirmed the importance of people and commitment in sustaining the platform. 

Members confirmed their confidence in TN-ITS leadership through the re-election of Christian Kleine as TN-ITS President, ensuring continuity as the platform advances standardisation, deployment and ecosystem alignment. 

The meetings concluded with the annual TN-ITS Awards, a moment dedicated to recognising those who have contributed in a concrete and visible way to the platform’s development: 

• Danish Road Directorate received the award for Best TN-ITS Service Uptake, highlighting strong engagement in implementation and use.

• Christian Kleine (HERE) received the award for Best Proposal for Rebranding, acknowledging a valuable contribution to strengthening the platform’s identity while preserving continuity.

Looking ahead to 2026 

The December meetings closed with a shared understanding: TN-ITS is progressing, but accelerating adoption will require continued focus – from strengthening the business case and expanding participation, to improving consistency, metadata and feedback mechanisms, and broadening the range of data types beyond speed limits. 

With major steps taken in standardisation, renewed efforts on deployment tools, active alignment through industry platforms, and exploratory work on cycling data, TN-ITS enters 2026 with strong momentum, backed by an engaged and committed community.
