Intelligent Transport Systems (ITS) are considered to be powerful tools for sustainable growth of mobility at all levels (local, regional, national, transnational). The book reviews the current Research & Development status, ranging from connected (and autonomous) cars and buses, to real-world large-scale field trials, data analysis and assessment of technological solutions. Standards and normative aspects in the domain of Electronic Fee Collection and Cooperative Systems oriented to probe data collection, safety and non-safety critical applications in vehicular networks, are studied.
