Vehicle C-ITS

C-Roads works in close collaboration with the Car-2-Car Communication Consortium. All C-Roads specifications are harmonized with the Basic System Profiles developed by the Car-2-Car Communication Consortium.

In addition, C-Roads provides an interoperability guide for Euro NCAP. Euro NCAP, the European New Car Assessment Program, includes “Local Hazards” in its Safe Driving Vehicle Assistance Protocol for 2026. Local Hazard warnings help drivers to drive attentively and prepare for upcoming hazards. These warnings can be conveyed via Direct Communication and via Cloud Communication. For Direct Communication, the EURO NCAP Program refers to the C-ROADS specifications, which explain when to send and how to interpret these hazard warnings, so that they can be understood in the same way throughout Europe.

The full set of C-ITS infrastructure specifications is available under releases.c-roads.eu.
