Nowadays, FM radio broadcasting provides road traffic information, such as TMC and TMC Pro (in Europe). Wide-area cellular communication (3G) technologies transmit incident reports, estimated travel delays and alternative routes to drivers at a reasonable timeliness. They also offer traffic telematic services ranging from breakdown assistance and emergency call to location-based information and news. It is common to all these services that they are based on (i) server-oriented communication via a 3G access network and (ii) subscription where the driver pays for usage and data transmission. Unlike existing approaches, the German research project NoW - Network on Wheels took an alternative approach that is based on direct and rapid communication among cars as well as between cars and road side communication equipment (subsumed under CAR-2-X), without the need for a coordinating infrastructure. The approach was enabled by proliferation of two main technologies: Wireless LAN IEEE 802.11 and positioning devices based on GPS. The project NoW - Network on Wheels was started in May 2004. Supported by the German Ministry of Education and Research (BMBF), project partners are car manufacturers BMW AG, Daimler AG (coordinator of the project), and Volkswagen AG together with Fraunhofer FOKUS, NEC Deutschland GmbH, Siemens AG (until 2006), IMST GmbH (from 2006), and Embedded Wireless GmbH (from 2006). Besides, the Universities Mannheim, Karlsruhe, and München and Carmeq GmbH co-operate within NoW. The project will end in May 2008. The project NoW is the successor of the pioneering research project FleetNet - Internet on the Road (2000 - 2003), which successfully studied and demonstrated the feasibility of vehicular communication based on IEEE 802.11 and ad hoc networking to support safety, floating car data, and Internet access. As the NoW project will end in May 2008, this paper gives a project overview and brings the various project contributions into context. The following two sections describe the developed CAR-2-X technology and summarize the main project achievements.
