Operating model
How ITS-G5 works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
ITS-G5 provides direct ad hoc communication among European ITS stations in vehicles, at the roadside, and in other transport contexts. It supports cooperative safety and traffic applications using the ETSI C-ITS stack, including standardized messages such as CAM and DENM. ITS-G5 is a regional access technology and should not be used as a synonym for the full C-ITS architecture.
