Abstract
Optimized, universal transmission of traffic information and the coding thereof by different terminals is permitted in a simple, inexpensive and efficient manner by apparatuses and a method for transmitting traffic information relating to a road traffic network from a traffic information control center to at least one terminal. In the control center, the segments of the road traffic network which are affected by the traffic information are either coded using a location coordinate table, available in the control center, in a form which represents the location of the segments, or are coded using a segment table, available in the control center, in a form which represents the identity of the segments without their location. The control center transmits to the terminal a selection information item which indicates which of the two above codings is used in the transmitted information.
