In a cooperative and intelligent transport system (C-ITS), the different participants should be treated individually. Some road users should be prioritized, albeit to varying degrees. This is especially true for emergency vehicles or public transport. In this context, it is important to prevent misuse, that an adversary gains access to these preferred user groups.


In the EVE project, a structured consideration of C-ITS is carried out from the point of view of giving priority to emergency vehicles or public transport. For this purpose, it is mandatory to define Service Specific Permissions for special user groups. Requirements are derived and implemented through the development of use cases and lifecycles, taking into account of the legal framework and cyber security. Different levels of priorization based on these use cases should be able to be processed accordingly in the overall C-ITS infrastructure system.


C-ITS enable a variety of new applications to use traffic networks more efficiently and safely. Automated communication with traffic signal systems and other networked road users can, e.g., give priority to blue-light organizations in order to reach the scene of an emergency more quickly. The KIRAS research project EVE ("Efficient Prioritization of Emergency Vehicles in Automated Road Traffic") is analyzing at the possibilities, limits and, above all, safety aspects of this C-ITS application.
