Abstract

The redundancy of transmitted traffic information or of traffic information which is to be transmitted is optimized by a method for transmitting traffic information from a traffic information center to at least one terminal device in a vehicle via a publicly receivable (e.g., DAB, RDS-TMC) communications channel or via a private communications channel (e.g., mobile radio), wherein a first reference zone is defined at or around the known or presumed stopping place of at least one vehicle to which information is to be conveyed at a first time point. At least a second reference zone is defined at or around at least one presumed stopping place of the vehicle at a second time point lying in the future in relation to the first time point. Traffic information generated for a reference zone and for a respective future time point with forecasting and/or traffic information determined for the current time point and for the respective current reference zone are/is compiled. Data representing traffic information with the time point to which it relates and/or the reference zone to which it relates are transmitted.
