Strengthening road safety through harmonised traffic information – SRTI message sets released
At C-Roads, we are committed to building a safer, smarter transport ecosystem across Europe. A cornerstone of this commitment is the continued evolution of the Safety Related Traffic Information (SRTI) Message Sets — a key resource that supports the implementation of EU Delegated Regulation No. 886/2013, part of the broader ITS Directive (2010/40/EU).
A Collaborative Achievement
This work was made possible through close collaboration among leading standardisation experts from the C-Roads Platform, Car2Car Communication Consortium, Data for Road Safety (DFRS) initiative, Traveller Information Service Association (TISA), DATEX II, and NAPCORE. It reflects years of coordinated work among European road safety and mobility stakeholders.
Why This Matters
The Delegated Regulation mandates the provision of safety relevant traffic information at no cost to the user. Here C-ITS services are in deployment based on the cooperation between C-Roads and C2C CC and following this principle by supporting European road users with high quality safety relevant information. Hereby safety relevant traffic information is exchanged bidirectionally between road infrastructures and vehicles. This information is available also coded in DATEX II format or made public in TMC or TPEG2. The document focusses on:
- The growing role of connected vehicles as new data sources in contributing real-time, safety-related information.
- The clarification of the use of safety-related data by integrating real-time vehicle inputs across Europe.
- Harmonisation with C-Roads Services ensuring all stakeholders are speaking the same “data language”.
- Interoperability guidance on location referencing, event code clarifications, and deeper insights into how data standards (DENM, DATEX II, TMC and TPEG2) translate seamlessly across systems without information loss.
The overall goal is to create a framework and practical guidance for ensuring high-quality, interoperable safety information for all European travellers.
What’s Next?
As vehicle connectivity and data-sharing continue to evolve, SRTI message sets will remain a foundational reference for future innovations in cooperative, connected, and automated mobility. At C-Roads, we remain dedicated to fostering this alignment, enabling safer journeys across the continent.
