  Abstract

It is the most important in the traffic information system how fast to transmit the traffic conditions on each road, or event such as RTM (Road Traffic Message). In order to operate the event information more efficiently in the TPEG system, it is likely that the effective transmission system shall be needed, and this paper will propose the improved transmission system; Breaking away from the conventional method which is to transmit the traffic information by using simple FIFO method while encoding it into TPEG data, the improved transmission system is to transmit the important information more quickly or to advance the transmission cycle by scheduling according to degree of its importance after deciding which one is the important traffic information by comparing the importance ratings in between diverse information. The traffic information with low importance rating is to be transmitted slowly, and its transmission cycle shall become slow as well. In the computer simulations, it is shown that the proposed approach enables to transmit more quickly a sudden change of traffic conditions and the important traffic data.
