Abstract

Disclosed herein is a method and apparatus for providing traffic information of public transportation means, such as a bus, and utilizing the provided information. A method of encoding public traffic information according to the present invention creates an identifier of bus information system, an ID of bus route, and information on all of bus stops pertaining to the bus route. The created information is organized to status information that is in turn incorporated into a transfer message. A sequence of transfer messages, each being constructed as described above, is wirelessly transmitted.

Claims

1. A method for processing traffic information, at a terminal including a receiver and a decoder, comprising:

receiving, at the receiver, the traffic information; and

decoding, at the decoder, the received traffic information,

wherein the traffic information includes a traffic message including a message management container and an event container,

wherein the message management container includes a message ID, a version number, and a message generation time,

wherein the event container includes a bus-stop-sequential-number-based bus information component, a bus-stop-ID-based bus information component, a section-ID-based bus information component, an additional information of bus route component, and an additional information component,

wherein the bus-stop-sequential-number-based bus information component is allocated a first identifier, the bus-stop-ID-based bus information component is allocated a second identifier, the section-ID-based bus information component is allocated a third identifier, the additional information of bus route component is allocated a fourth identifier, and the additional information component is allocated a fifth identifier,

wherein the bus-stop-sequential-number-based bus information component includes a sequential number of a stop belonging to the route,

wherein the bus-stop-ID-based bus information component includes a system identifier for identifying a traffic ID system, identification information for a route, and identification information for stops belonging to the route,

wherein the section-ID-based bus information component includes a section ID between two consecutive stops belonging to the route,

wherein the additional information of bus route component includes a scheduled time for a first and last buses component and a bus operation interval component,

wherein the scheduled time for the first and last buses component is allocated a sixth identifier and the bus operation interval component is allocated a seventh identifier,

wherein the scheduled time for the first and last buses component includes a scheduled time for a first bus, a scheduled time for a last bus, and a day of a week of the scheduled time for the first bus and the scheduled time for the last bus,

wherein the bus operation interval component includes information of a time duration including number of years, number of months, number of days, number of hours, number of minutes, and number of seconds, and

wherein the additional information component includes a language code.

2. The method of claim 1, wherein the event container further includes a country code.

3. The method of claim 1, wherein the event container further includes information on a number of the stops.

4. The method of claim 1, wherein the section ID expresses a current location of a bus using an identifier assigned to a section of the route between the two consecutive stops at which the bus is currently located.

5. The method of claim 1, further comprising determining, by the decoder, a most appropriate bus location component type for a bus route in consideration of a current situation and creating, by the encoder, bus location components of the determined bus location component type.

6. The method of claim 1, wherein the event container further includes fare information for the route.

7. The method of claim 1, wherein the event container further includes information for a turning point of the route.

8. The method of claim 1, further comprising applying, by the decoder, different transmission frequencies to a section travel time component of the traffic information, a route additional information component of the traffic information, and a bus stop list component of the traffic information as a compared to a bus location component of the traffic information.

9. The method of claim 1, wherein the traffic information further includes information on a number of buses expected to arrive at a bus stop and information on each bus to arrive.

10. An apparatus for processing traffic information, comprising:

a receiver configured to receive the traffic information; and

a decoder configured to decode the received traffic information,

wherein the traffic information includes a traffic message including a message management container and an event container,

wherein the message management container includes a message ID, a version number and a message generation time,

wherein the event container includes a bus-stop-sequential-number-based bus information component, a bus-stop-ID-based bus information component, a section-ID-based bus information component, an additional information of bus route component, and an additional information component,

wherein the bus-stop-sequential-number-based bus information component is allocated a first identifier, the bus-stop-ID-based bus information component is allocated a second identifier, the section-ID-based bus information component is allocated a third identifier, the additional information of bus route component is allocated a fourth identifier, and the additional information component is allocated a fifth identifier,

wherein the bus-stop-sequential-number-based bus information component includes a sequential number of a stop belonging to the route,

wherein the bus-stop-ID-based bus information component includes a system identifier for identifying a traffic ID system based on a district, identification information for a route, and identification information for stops belonging to the route,

wherein the section-ID-based bus information component includes a section ID between two consecutive stops belonging to the route,

wherein the additional information of bus route component includes a scheduled time for a first and last buses component and a bus operation interval component,

wherein the scheduled time for the first and last buses component is allocated a sixth identifier and the bus operation interval component is allocated a seventh identifier,

wherein the scheduled time for the first and last buses component includes a scheduled time for a first bus, a scheduled time for a last bus, and a day of a week of the scheduled time for the first bus and the scheduled time for the last bus,

wherein the bus operation interval component includes information of a time duration including number of years, number of months, number of days, number of hours, number of minutes, and number of seconds, and

wherein the additional information component includes a language code.

11. The apparatus of claim 10, wherein the event container further includes information on a number of the stops.

12. The apparatus of claim 10, wherein the section ID expresses a current location of a bus using an identifier assigned to a section of the route between the two consecutive stops at which the bus is currently located.

13. The apparatus of claim 10, wherein the decoder is configured to determine a most appropriate bus location component type for a bus route in consideration of a current situation and create bus location components of the determined bus location component type.

14. The apparatus of claim 10, wherein the event container further includes fare information for the route.

15. The apparatus of claim 10, wherein the event container further includes information for a turning point of the route.

16. The apparatus of claim 10, wherein the decoder is configured to apply different transmission frequencies to a section travel time component of the traffic information, a route additional information component of the traffic information, and a bus stop list component of the traffic information as a compared to a bus location component of the traffic information.
