DAB has got functionalities for traffic information as it existed for FM.
The equivalent of the Traffic Programm (TP) (flag for station having traffic information in the program) is implemented in FIG 0/18.
The equivalent for the Traffic Announcement (TA) (flag activated when the announcement happens, interrupt listeners) is implemented in FIG 0/19
As of today (31/7/2015) these functionalities are not implemented in ODR-DabMux.
FIG 0/18 is static and can be added as an option in the config file.
FIG 0/19 should be triggered by an external trigger (via ZMQ ?) or forced as always on in the config (useful for some case for emergency mux).
