Innovative concepts and simulation studies have enabled the seamless integration of advanced sensor technology into vehicles and the (road) infrastructure. The infrastructure is divided into edge areas, with local computing resources enabling decentralized processing on site. Edge information is aggregated in the cloud for efficient data utilization. Communication between the layers requires integrated software for vehicles and infrastructure to enable smooth interaction between the various devices. The software is combined in a software stack, which we call AI Mobility OS in the BeIntelli project.
