The European Car-to-Car Communication Consortium in relation with the American Vehicle Safety Communication project has been playing a key role in the development of the concepts and technologies which are now at the origin of the standardization activities and research projects (PREVENT, SAFESPOT, CVIS) being introduced. Many safety applications (some of them being summarized here) will use this standard infrastructure for contributing to a safer road environment. Along the ISO OSI reference model the authors describe medium access control, routing in WAVE/DSRC (Dedicated Short Range Communications), 802.11p, and accompanying standards based on the communication architecture defined by the Car-to-Car Communication Consortium and the National Vehicle Infrastructure Integration Consortium (VIIC), as within the Federal ITS Program (RITA). Furthermore, this book introduces and describes future automotive applications such as cooperative driving utilizing such car-2-X (or vehicle-2-x) communication between vehicles and road infrastructure. Validation of these novel applications is a must before market introduction. Therefore this book introduces comprehensive simulation environment combining existing approaches for application, traffic and network simulation.

Résumé
Universal vehicular communication promises many improvements in terms of ac- dent avoidance and mitigation, better utilization of roads and resources such as time and fuel, and new opportunities for infotainment applications. However, before widespread acceptance, vehicular communication must meet challenges comparable to the trouble and disbelief that accompanied the introduction of traf c lights back then. The rst traf c light was installed in 1868 in London to signal railway, but only later, in 1912, was invented the rst red-green electric traf c light. And roughly 50 years after the rst traf c light, in 1920, the rst four-way traf c signal comparable to our today's traf c lights was introduced. The introduction of traf c signals was necessary after automobiles soon became prevalent once the rst car in history, actually a wooden motorcycle, was constructed in 1885. Soon, the scene became complicated, requiring the introduction of the right-of-way philosophy and later on the very rst traf c light. In the same way the traf c light was a necessary mean to regulate the beginning of the automotive life and to protect drivers, passengers, as well as pedestrians and other inhabitants of the road infrastructure, vehicular communication is necessary to accommodate the further growth of traf c volume and to signi cantly reduce the number of accidents.
