Abstract

A method of transmitting digitally coded traffic information is described, in which a digitally coded traffic message including location information is transmitted is standard format, preferably according to the TMC method. When the location information in the traffic message requires change and/or completion, a header is provided in front of the traffic message, which indicates that additional information including changes or additions to the location information in the traffic message follows the traffic message. A receiver for reception and analysis of the digitally coded traffic information is also provided, which analyses the traffic information including the additional information to obtain the changed or completed location information.
