The Cooperative Intelligent Transport System (C-ITS) enables vehicles to inform each other about traffic and, in particular, dangerous situations. When a vehicle with its sensors detects a state important for other road users, such as obstacles, traffic jams, black ice, or aquaplaning, then it provides this observation via data exchange.[1] Vehicles may also exchange messages with road furniture such as signals and road signs.[2]
C-ITS is envisaged to launch in three phases; in the first, it will be used to transmit warnings; in the second, communication between devices will be used to combine data to issue warnings, and in the third, vehicles will cooperate to coordindate their behavior.[3] The vehicles can thus react in a coordinated manner to an event, for example to dodge an obstacle or brake.
As of 2025[update], C-ITS was being experimentally deployed in several countries. Multiple countries have plans to deploy C-ITS, including Austria, Czechia, Germany, Italy and Spain.[4][5][6][7]
Technology
[edit]C-ITS is a vehicle-to-everything (V2X) system based on the IEEE 802.11p vehicle to vehicle wireless local area network standard. The protocols used between C-ITS participants are defined in a suite of standards documents defined by ISO and CEN.[8]
