Traffic information service has been attempted variously based on commercial wireless communication network and broadcasting network since the 1990s. It was confirmed that RDS (Radio Data System) was developed because it was confirmed that the dual broadcasting network method was relatively inexpensive and superior in transmission characteristics.                         

RDS transmits traffic information using subcarriers of FM. However, RDS has been difficult to spread widely due to the very low transmission speed of 1.2kbps. Although there was a function to automatically connect frequencies across the country, the amount of characters that could be delivered in one minute was limited to 20 characters.

The FM DARC (DAta Radio Channel) was first developed in Japan in 1995 and was jointly developed by companies in Japan and Sweden. DARC service provided in Korea has good radio wave propagation characteristics by recording 16kbps transmission speed 10 times faster than RDS and utilizing high quality FM frequency band. In addition, the DARC service is an advanced transportation and traveler information service that can utilize the national broadcasting network, which is low in facility construction costs and free of communication charges.

The Transport Protocol Expert Group (TPEG) was launched in 1997 by the European Broadcasting Union (EBU) project group to provide transportation and travel information for broadcasting and the Internet. Unlike conventional DARC systems, various transmission media capable of loading additional data are considered, not limited to broadcasting networks such as FM.

However, the conventional traffic information service focuses on providing information from the service provider. Therefore, the conventional traffic information processing method on the user side merely receives and displays traffic information provided by the service provider. Therefore, according to the conventional traffic information processing method, there is a problem that the user may feel confusion in the vast and distracted traffic information.

The technical problem to be achieved by the present invention is to provide a traffic information processing method that can obtain the necessary traffic information by appropriately processing the traffic information broadcast in the traffic information processing method.
