The importance of traffic management systems increases with the number of vehicles and the traffic density. Especially metropolitan areas constitute logistic bottlenecks for cargo services and passenger transportation, with negative impact on economy. Furthermore, traffic hotspots contribute significantly to the environmental pollution. Future cooperative communication technologies are expected to improve the traffic flow and to advance safety on the road. Communicating cars are expected to form an essential part of future traffic safety and traffic management systems. Many national and international projects treat the specification and implementation of new car communication technologies, whereas most ongoing activities focus on a realization with mobile ad-hoc networks based on Wireless LAN (802.11). Motivated by the German public funded project Cooperative Cars (CoCar), this paper presents the realization of automotive data services based on UMTS. One exemplary cooperative car application is selected in order to highlight the potential of UMTS for realizing automotive data services. In CoCar, the implementation of more or less time critical driving assistance and warning applications in addition to periodically transmitted FCD and other data services for several use cases will be analyzed by means of transmission delay as well as network capacity. The feasibility of the applications based on UMTS will be evaluated and possible network optimizations will be developed. Results will be published according to the project progress.
