Road Operation Opportunities Due to Distributed ODD Attribute Value Awareness

Abstract The paper presents the concept of Distributed Operational Design Domain (ODD) attribute Value Awareness (DOVA) developed by TM4CAD (Traffic Management for Connected and Automated Driving), a CEDR-funded project involving MAPtm (coordinator), Traficon, Transport & Mobility Leuven, and WMG, University of Warwick, as well as Hironao Kawashima from Japan and Steven Shladover from USA as experts. TM4CAD explored the role of infrastructure systems and connected vehicle data exchange in creating ODD (Operational Design Domain) attribute value awareness for Automated Driving Systems (ADS), so that each ADS can be forewarned before it encounters conditions in which it will not be capable of operating, i.e. ODD departure. TM4CAD proposed various approaches for providing distributed ODD attribute value information and its importance, acquisition principles, and corresponding data quality requirements. It also discussed the basic mechanisms of ODD management via specific use cases, which build on the interaction between traffic management systems and the ADS, and highlighted the need for stronger interactions between national road authorities and ADS developers.
