This study sought to identify the European requirements for the national deployment and operation of C-ITS services and to develop a proposal for establishing the necessary capabilities for service deployment. This included consideration of the requirements set by the EU C-ITS security and certificate policies, the EU C-ITS Security Credential Management System (EU CCMS), and the C-Roads Platform regarding the implementation and operation of central C-ITS stations and interchange servers, as well as aspects related to privacy protection. The methods used included a literature review, steering group work, expert interviews and workshops. Valuable contributions also came from consultants, relevant agencies, and the steering group members’ own expertise.
