Abstract

A method and apparatus for providing public transportation information and using the provided information, are discussed. When creating information on each bus stop such as the bus stop ID and a distance between bus stops, a method for encoding transportation information in accordance with an embodiment creates information on nearby subway stations accessible on foot and/or nearby bus stops located on bus routes (or bus lines) that do not pass the bus stop as well, and constructs status information containing the created information. One or more messages containing the status information can be transmitted wirelessly.

Claims

1. A method for providing transportation information, comprising:

creating, in a computing device, first information on each stop of a public transportation route, second information on an available route-transfer station and third information on an available route-transfer stop;

creating, in the computing device, fourth information on a current position of at least one vehicle in service on the public transportation route, fifth information on a vehicle arrival time for each public transportation route passing the available route-transfer station, and sixth information on a vehicle arrival time for each public transportation route passing the available route-transfer stop;

classifying, in the computing device, the first, second, third, fourth, fifth and sixth information into route-based information and vehicle-stop-based vehicle service information; and

transmitting, from the computing device, the route-based information and the vehicle-stop-based vehicle service information via different containers in a sequence of messages formed in a hierarchical structure and including traffic information,

wherein information on a nearby station and/or a nearby vehicle stop available for transfer from a bus stop is generated using both of the route-based information and the vehicle-stop-based information.

2. The method of claim 1, wherein the second information comprises:

information for identifying the available route-transfer station; and

information for identifying a distance between the available route-transfer station and one of the stops.

3. The method of claim 1, wherein the third information comprises:

information for identifying the available route-transfer stop;

information for identifying a distance between the available route-transfer stop and another stop; and

information for identifying public transportation routes passing the available route-transfer stop.

4. The method of claim 1, wherein the second information comprises:

information for identifying the available route-transfer station; and

information for identifying a distance between the available route-transfer station and the available route-transfer stop.

5. The method of claim 1, wherein the third information comprises:

information for identifying the available route-transfer stop;

information for identifying a distance between the available route-transfer stop and the stop; and

information for identifying a public transportation route passing the available route-transfer stop.

6. The method of claim 1, wherein the message formed in the hierarchical structure is a Transport Protocol Expert Group (TPEG) message.

7. A method for decoding transportation information, comprising:

extracting, from a received sequence of messages, transportation information classified into route-based information and vehicle-stop-based vehicle service information, the route-based information and the vehicle-stop based vehicle service information being carried by different containers of the sequence of messages formed in a hierarchical structure and including traffic information;

extracting, from the different containers, information on each stop of a public transportation route, information on an available route-transfer station, information on an available route-transfer stop, information on a current position of at least one vehicle in service on the public transportation route, information on a vehicle arrival time for each public transportation route passing the available route-transfer transfer station, and information on a vehicle arrival time for each public transportation route passing the available route-transfer stop; and

outputting information on a nearby station and/or a nearby vehicle stop available for transfer from a vehicle stop upon receiving a selection input of the vehicle stop.

8. The method of claim 7, wherein the information on the station available for transfer comprises:

information for identifying the available route-transfer station; and

information for identifying a distance between the available route-transfer station and one of the stops.

9. The method of claim 7, wherein the information on the stop available for transfer comprises:

information for identifying the available route-transfer stop;

information for identifying a distance between the available route-transfer stop and another stop; and

information for identifying public transportation routes passing the available route-transfer stop.

10. The method of claim 7, wherein the information on the station available for transfer comprises:

information for identifying the available route-transfer station; and

information for identifying a distance between the available route-transfer station and the available route-transfer stop.

11. The method of claim 7, wherein the information on the stop available for transfer comprises:

information for identifying the available route-transfer stop;

information for identifying a distance between the available route-transfer stop and the stop; and

information for identifying a public transportation route passing the available route-transfer stop.

12. The method of claim 7, wherein the message information formed in the hierarchical structure is a Transport Protocol Expert Group (TPEG) message.

13. An apparatus for providing transportation information, comprising:

a demodulator;

a decoder;

an interface unit; and

a controller operatively connected to the demodulator, the interface unit, and the decoder, the controller configured to

extract, from a received sequence of messages, transportation information classified into route-based information and vehicle-stop-based vehicle service information, the route-based information and the vehicle-stop based vehicle service information being carried by different containers of the sequence of messages formed in a hierarchical structure and including traffic information,

extract, from the different containers, information on each stop of a public transportation route, information on an available route-transfer station, information on an available route-transfer stop, information on a current position of at least one vehicle in service on the public transportation route, information on a vehicle arrival time for each public transportation route passing the available route-transfer transfer station, and information on a vehicle arrival time for each public transportation route passing the available route-transfer stop, and

output information on a nearby station and/or a nearby vehicle stop available for transfer from a vehicle stop upon receiving an input from the interface unit.

14. The apparatus of claim 13, wherein the information on the station available for transfer comprises:

information for identifying the available route-transfer station; and

information for identifying a distance between the available route-transfer station and one of the stops.

15. The apparatus of claim 13, wherein the information on the stop available for transfer comprises:

information for identifying the available route-transfer stop;

information for identifying a distance between the available route-transfer stop and another stop; and

information for identifying public transportation routes passing the available route-transfer stop.

16. The apparatus of claim 13, wherein the interface unit is further configured to enable a user to request one of

the information on each stop of a public transportation route,

the information on an available route-transfer station,

the information on an available route-transfer stop,

the information on a current position of at least one vehicle in service on the public transportation route,
