Abstract
A method is proposed for transmitting traffic announcements via Digital Audio Broadcasting (DAB), making use of the TMC code, where it is possible to have a simple allocation of the audio signals to the TMC data. In this context, the allocation is predetermined by the data frame of the digital transmitter and by the corresponding data protocol.
