Abstract

A reduction in telecommunications costs in the transmission of extensive data from a telematic terminal unit in a vehicle to a central station is made possible by a method for the transmission of location data implicating the location of the terminal unit in a traffic network at a point in time and of measurement data impliciting other characteristics of the traffic network at a location and/or at a time to the central traffic station, which location data and measurement data are detected by the terminal unit, particularly a telematic terminal unit for a vehicle. At least some of the data records transmitted from the terminal unit to the central traffic station contain only location data and some of the data records transmitted from the terminal unit to the central traffic station contain measurement data.
