Requirements of Traffic Telematics to Spatial Databases

Traffic telematics comprises services like traffic information, navigation, and emergency call services. Providers of such services need large spatial databases especially for the representation of detailed street networks. However, the implementation of the services requires a functionality which cannot be offered by a state-of-the-art spatial database system. In this paper, some typical requirements concerning the determination of a vehicle position, the traffic-depending computation of routes, and the management of moving spatial objects are discussed in respect to spatial database systems. It will be shown, that these tasks demand for the capability to handle spatio-temporal data and queries.
