sim TD : a car-to-X system architecture for field operational tests [Topics in Automotive Networking]

Car-to-car and car-to-infrastructure communications are considered as a key technology for safe and intelligent mobility in the future. In the German project simTD, car-to-x communication is shifting from a pure research topic toward a first deployment of such a system: the goal of simTD is to test car-to-x applications in a real metropolitan field trial. The simTD scenario includes vehicles, roadside units, and infrastructural facilities for traffic and test management. Besides these domains, several third parties are involved to provide access to additional services. The main communication partners are furthermore distributed over a wide area including highway, suburban, and urban scenarios. As a result, such a system requires a commonly accepted architecture of the individual components and a seamless communication network for reliable and efficient information interchange. In this article we propose the simTD system architecture and the components necessary for successful deployment in the large-scale field trial.

Communication architecture for cooperative systems in Europe

Wireless communications for intelligent transportation systems promise to be a key technology for avoiding the traffic nightmares of today - accidents and traffic jams. But there is one major challenge to be overcome before such a cooperative system can be put into place: standardization. This article provides an overview of the technical developments in Europe and their convergence toward a set of European standards. We address the current state of the standardization activities and the potential scenarios and use cases, and we describe the fundamental concepts of a European communication architecture for cooperative systems.
