Infrastructure support for automated driving: Further enhancements on the ISAD classes in Austria

A classification scheme for infrastructure support for automated driving (ISAD) has recently been introduced, which groups the availability of static and dynamic infrastructure information together with communication capabilities into classes. In this paper, this classification is applied to the Austrian motorway network and exemplifies how different classes of infrastructure support can be provided on a road network, ranging from static and dynamic map data to the latest technology for microscopic traffic perception and the integration with the C-ITS deployment. Such an infrastructure classification can be regarded as a tool to systematically define road sections where automated driving functions can operate under their operational design domain (ODD) and to guide infrastructure upgrades
