CPS Road Network Scenarios Analysed for Dependability and Standardization

Infrastructure planning of transport and mobility is a very complex and challenging issue for planners and decision-makers. Cooperative Intelligent Transport Systems (C-ITS) allow here not only improved information and planning in singular vehicle but optimization of the overall traffic and consideration of special needs. Understanding the design, structure and integration of the necessary infrastructure and other road users must become an integral part of developing modern vehicles and modern infrastructures. There are already existing concepts for special service permission for accessing road and traffic services which can improve public safety, decrease the environmental impact and improve the overall traffic flow. In this work, we analyse a CPS road network scenario, with both general and emergency processes, where vehicles and infrastructure are able to communicate with each other concerning dependability. We highlight challenges and propose building blocks towards a holistic system engineering method. Furthermore, we give a short overview of state-of-the-art methods proposed by standards and discuss their shortcomings concerning the raised dependability issues.
