C-ITS Authority

12. July 2016

Cooperative Intelligent Transport Systems (C-ITS) are close to large-scale deployment. This raises questions about trust, rights and duties, as C-ITS deals with safety of human life and property, and with private data.

In order to approach these questions, the origin of C-ITS, its nature, and involved entities need to be understood. Some findings are presented in the below list in chronological order:

This short list shows, that the major expertise and promotion of C-ITS is done in CEN/ISO, and thus these two SDOs are the real advocates of ITS.

A problem of general interests and business models arises from the fact, that three major big interest groups have to meet in a single device, i.e. in the vehicular ITS station unit (ITS-SU), and each of these groups would like controlling the whole C-ITS, i.e. operate it as a closed system. Note that this conflict is not at all a technical conflict, as the CALM approach serves all technical needs. C-ITS however is designed as a "chaotic system", i.e. a system that is not necessarily operated as cellular networks are; nevertheless roles and responsibilities can be identified for specific C-ITS services or service domains.

Every user that has a certified ITS-SU becomes part of C-ITS. Operation of C-ITS thus builts on a trusted ITS-SU. A C-ITS authority, in general, is needed to set up the minimum requirements and rules for a trusted ITS-SU and its communications and data sharing between ITS applications. This authority has also to be in charge of managing appropriate identifier registries (see EN ISO 17419). CEN and ISO, being the advocates of ITS standards, definitively must be part of this authority. User groups such as road operators, authorities, car OEMs, and end user organizations should also contribute to the C-ITS authority, which finally will create a C-ITS allicance (similar to the WiFi alliance).

As C-ITS is not just targeted for use in a single region, the C-ITS authority has to be a hierarchical organisation applying the principle of subsidiarity such that regional decision committees will run the regional business, and a global kind of steering committee will ensure appropriate synchronization between the regions. As C-ITS is of public interest, NGOs (non-governmental organizations) should not at all play a dominant role in the C-ITS authority.

In case of any questions please contact the C-ITS core experts.
