One of the most important application of the RDS. Transmits traffic intensity info, car accident news and etc. to the moving vehicles by special radio stations.
       The broadcast of TP signal inside the RDS signal means that the radio station makes Traffic Announcements. If TA signal is broadcasted before TP signal this means that another radio station broadcasts TA signal over EON.
       If the transmitter enables TA signal and the radio receiver has TA suppoort and driver listening to that station
       tape or CD player is going to stop playing
       radio receiver's volume automatically increases.
      So radio listener never misses the Traffic Anonuncement of the radio station.
