Cooperative intelligent transport systems (C-ITS) enable ITS users to interact and cooperate by exchanging secured and trusted messages without prior knowledge of each other and in a non-discriminatory manner. The EU C-ITS security credential management system has three central roles that the Commission shall be responsible for ensuring are executed. Priority area IV is dedicated to ITS services for Connected and Automated Mobility (CCAM). Work on specifications under the ITS Directive will restart in 2026, covering the EU C-ITS security credential management system, harmonised C-ITS services, and fostering development and implementation of C-ITS. Currently, 2.5 million vehicles are sold and 20,000 km of roads are equipped with C-ITS, with 100,000 km covered by C-ITS services across more than 50 European cities in 21 European countries.
