The event provided an opportunity to validate C-ITS services under real-world conditions, exchange technical expertise, and demonstrate how connected vehicles and road infrastructure can communicate to improve road safety and traffic efficiency.
Day 1: Testing C-ITS Services on Motorways
The first day focused C-ITS applications on the motorway, with particular attention to Local Hazard Warning services referenced in the Euro NCAP 2026 protocol.
Among the use cases tested was Emergency Vehicle Approaching, which enables connected vehicles to receive information about approaching emergency vehicles, supporting increased driver awareness and safer responses to potentially critical traffic situations.
The pilot site also supported the testing of next-generation C-ITS applications, including In-Vehicle Signage (IVIM). This service enables traffic signs and relevant road information to be communicated directly to vehicles, helping drivers receive timely and location-specific information.
These activities contributed to assessing the interoperability of C-ITS services across different systems and implementations, supporting the wider objective of seamless cooperative mobility across European borders.
Day 2: Exploring Urban C-ITS Applications in Vienna
On the second day, testing moved into the urban environment of Vienna, where participants explored C-ITS applications.
The activities focused on Signalized Intersection services along Vienna's inner Ring Road, demonstrating communication between traffic signal infrastructure and connected vehicles.
The tested services included SPATEM, MAPEM, SREM and SSEM.
Together, these services support improved traffic awareness, more efficient intersection management, and the integration of connected vehicles into urban traffic systems.
An urban guided tour starting at Schwedenplatz offered participants the opportunity to experience C-ITS applications in a real-world city environment and gain insights into their implementation.
Advancing Interoperable C-ITS Deployment Across Europe
The two-day Austrian C-Roads Cross-Test highlighted the importance of testing C-ITS applications across different road environments and technical implementations.
The results and experiences gained from the testing activities contribute to the ongoing work of the C-Roads Platform, supporting harmonised C-ITS deployment and interoperability across Europe.
