Method and apparatus for providing transportation status information and using it
First Claim
1. An apparatus for decoding a Transport Protocol Expert Group (TPEG) traffic information message comprising:
- a decoder for extracting traffic information from the TPEG traffic information message, the extracted traffic information includingmessage management information including (1) message identification (ID) information indicating that the traffic information is status information and (2) a generation time of the traffic information message,status information including traffic-flow status information of a link, andlocation information including latitude and longitude information of the link corresponding to the traffic-flow status information; and
a controller for outputting the traffic-flow status information by referring to the location information,wherein the status information further includes additional information in the form of text data and a language code identifying a language of the text data, the location information further includes vertex information of a vertex within the link, wherein the vertex information includes longitude and latitude information of the vertex, the latitude and longitude information of the link being different from the latitude and longitude information of the vertex.

Abstract
A method and apparatus for providing road status information and using the same are disclosed. A method for encoding traffic information includes the steps of: generating message management information including message identification (ID) information indicating that the traffic information is status information; generating status information including traffic status information; generating location information corresponding to the traffic status information; and generating a traffic information message including the message management information, the status information, and the location information. Therefore, the method provides a vehicle driver who travels along a traffic-jam road or congested road with road traffic status information in real time, such that the vehicle driver can arrive a desired destination within the shortest time using predicted road traffic information.
