Infrastructure Supported Automated Driving in Transition Areas – a Prototypic Implementation

Abstract

When an automated vehicle (AV) of level 3 and above arrives at an area on the road which is not part of its operational design domain (ODD), it is forced to perform a transition of control (ToC) to the driver. If the driver is not responding, the ToC fails and a minimum risk maneuver (MRM) needs to be executed. When the penetration rate of such AVs on the roads is high, this will negatively impact traffic efficiency and safety. In EU H2020 TransAID, infrastructure supported traffic management measures have been investigated which reduce these negative impacts. The measures and their effects are tested intensively in simulation. To demonstrate that the measures could also be applied to the real world, feasibility assessments with real-world prototypes have been performed. This paper shows how the measures have been implemented in ITS-G5 communication, infrastructure and connected automated vehicles (CAV), and how the prototypes have been tested.
