Cooperative Intelligent Transport Systems (C-ITS) characterises the more modern version of ITS where communication among vehicles using wireless technology is possible, which enables them to interact not only with each other but also with the road infrastructure and even with pedestrians or cyclists. Such functionalities enable a coordination and cooperation between road users, which allow for the advanced management of traffic and mobility, and can serve as technological basis for new mobility solutions (e.g. CCAM, MaaS).

Through enhanced cooperation and traffic management, C-ITS can reduce congestion and increase the quality of transport services, delivering better accessibility and improved mobility for all. In this way, C-ITS constitutes an effective instrument for existing over-burdened traffic systems to implement innovative, sustainable visions tackling traffic movements and at the same time visualizing, monitoring and constantly evaluating traffic situations. As exchage of data and information are made possible through C-ITS, facilitating a more harmonized intermodal traffic infrastructure, services like dynamic lane changing, alternative route choice, improved traffic signalization, could be established. C-ITS capabilities can significantly improve road safety, through the cooperation of the different road users and the implementation of support functionalities to minimise human-errors resulting in traffic accidents.

C-ITS also enables a more efficient use of road space, by means of an optimised traffic flow and performance. Finally, it facilities eco-driving and provides opportunities to prioritise sustainable modes, resulting in reduced pollution and GHG emissions (climate protection). A more efficient and sustainable multimodal mobility network can thus be developed, with innovative services which can better address user needs and shift their travel behaviour towards more environmental friendly modes.
