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.

Claims

1. A method for encoding traffic information comprising 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.

2. The method according to claim 1, wherein the message management information further includes information of a transmission time of the traffic information message.

3. The method according to claim 1, wherein the traffic status information includes at least one of traffic-flow status information, traffic-flow status prediction information, and additional information.

4. The method according to claim 3, wherein the status information includes an identifier (ID) indicating whether the traffic information is the traffic-flow status information, or the traffic-flow status prediction information, or the additional information.

5. The method according to claim 3, wherein the additional information is configured in the form of text data.

6. A method for decoding a message of traffic information comprising the steps of:

a) extracting message management information including message identification (ID) information indicating that the traffic information is status information;

b) extracting status information including traffic status information and location information corresponding to the traffic status information; and

c) decoding the status information and the location information, and outputting the traffic status information.

7. The method according to claim 6, wherein the message management information further includes information of a generation time of the traffic information message.

8. The method according to claim 6, wherein the traffic status information includes at least one of traffic-flow status information, traffic-flow status prediction information, and additional information.

9. The method according to claim 8, wherein the status information includes a specific identifier (ID) indicating whether the traffic information is the traffic-flow status information, the traffic-flow status prediction information, or the additional information.

10. The method according to claim 8, wherein the additional information is configured in the form of text data.

11. An apparatus for decoding a message of traffic information comprising:

a decoder for extracting message management information including message identification (ID) information indicating that the traffic information is status information, extracting status information including traffic status information and location information corresponding to the traffic status information, and decoding the status information and the location information;

a display; and

a controller for displaying the traffic status information on the display by referring to the location information.

12. The apparatus according to claim 11, wherein the controller extracts at least one of traffic-flow status information, traffic-flow status prediction information, and additional information from the traffic status information, and displays the extracted information on the display.

13. The apparatus according to claim 12, wherein the additional information is configured in the form of text data.

14. A method for encoding traffic information comprising 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-flow status information of a link;

generating location information including information of the link corresponding to the traffic-flow status information; and

generating a traffic information message including the message management information, the status information, and the location information.

15. The method according to claim 14, wherein the traffic-flow status information includes average speed data of the link.

16. The method according to claim 14, wherein the traffic-flow status information includes travel time data of the link.

17. The method according to claim 14, wherein the traffic-flow status information includes delay time data of the link.

18. The method according to claim 14, wherein the traffic-flow status information includes traffic delay degree data of the link.

19. A method for decoding a message of traffic information message comprising the steps of:

extracting message management information including message identification (ID) information indicating that the traffic information is status information;

extracting status information including traffic-flow status information of a link and location information including information of the link corresponding to the traffic-flow status information; and

decoding the status information and the location information, and outputting the traffic-flow status information.

20. The method according to claim 19, wherein the traffic-flow status information includes average speed data of the link.

21. The method according to claim 19, wherein the traffic-flow status information includes travel time data of the link.

22. The method according to claim 19, wherein the traffic-flow status information includes delay time data of the link.

23. The method according to claim 19, wherein the traffic-flow status information includes traffic congestion type of the link.

24. An apparatus for decoding a message of traffic information message comprising:

a decoder for extracting message management information including message identification (ID) information indicating that the traffic information is status information, extracting status information including traffic-flow status information of a link and location information including information of the link corresponding to the traffic-flow status information, and decoding the status information and the location information;

a display; and

a controller for displaying the traffic-flow status information on the display by referring to the location information.

25. The apparatus according to claim 24, wherein the controller controls to extract average speed data of the link from the traffic-flow status information, and display the extracted average speed data.

26. The apparatus according to claim 24, wherein the controller controls to extract travel time data of the link from the traffic-flow status information, and display the extracted travel time data.

27. The apparatus according to claim 24, wherein the controller extracts delay time data of the link from the traffic-flow status information, and displays the extracted delay time data.

28. The apparatus according to claim 24, wherein the controller extracts traffic congestion type data of the link from the traffic-flow status information.
