How can a digital twin sustainably enhance integration and service quality for road authorities?

Towards the vision of cooperative, connected and automated mobility (CCAM) smart road services enabling communication between participants at the information level seem to be necessary. This paper aims at providing a framework for the integration of key concepts like operational design domains (ODD) and infrastructure-based support for automated driving (ISAD) into an umbrella digital twin as developed in the project DIGEST. A prototype concept for advanced forms of information management for a homogenous traffic situation representation is proposed. The concept of ODD Aware Traffic Management provides the ground for the digital twin, which shall support all vehicles in their decision-making. The intermediate project results contribute to the conference theme 'Innovative Infrastructure for Europe 2030' with the use of intelligent, resilient and cooperative infrastructure systems.
