Being a part of Intelligent Transport Systems, cooperative ITS (C-ITS or cooperative systems) encompass a group of technologies and applications that allow effective data exchange through wireless communication technologies between components and actors of the transport system, very often between vehicles (vehicle-to-vehicle or V2V) or between vehicles and infrastructure (vehicle-to-infrastructure or V2I).

The deployment of C-ITS is an evolutionary process that will start with the less complex use cases. These are referred to as “Day-1-services”, encompassing messages about traffic jams, hazardous locations, road-works and slow or stationary vehicles, as well as weather information and speed advises to harmonise traffic. Using probe vehicle and infrastructure-related data, all C-ITS services shall be transmitted directly into the vehicles in a way that allows users to get informed but not distracted.

C-Roads is a platform of Member States working on the deployment of harmonised and interoperable C-ITS services in Europe. The C-Roads Platform approach will pursue cooperation such as sharing experiences and knowledge regarding deployment and implementation issues, as well as user acceptance. It will follow a bottom-up approach that will include national pilots.

C-Roads Spain is part of the C-Roads Platform and includes the operation and testing of Day 1 and Day 1.5 C-ITS services as recommended by the C-ITS Platform in five pilot sites. This Spanish C-ITS pilots will deploy the C-ITS services using hybrid communication technologies (cellular based communications and ITS-G5).

C-Roads Spain main objective is to pave the way for the future roll-out and large scale deployment of C-ITS services in Spain, in cooperation with other Member States within C-Roads Platform so as to ensure seamless and harmonised services throughout Europe.
