Abstract

A method, apparatus, and service station for providing a location-based transportation information service. The method for providing a location-based traffic information service includes receiving a traffic message indicating a traffic condition, determining a traffic information service station matching the traffic message in terms of location, and dispatching the traffic message to the matched traffic information service station such that the traffic message is broadcasted within the service range of the matched traffic information service station. Corresponding apparatus and traffic information service station are also disclosed. According to embodiments of the present invention, a location-specific real-time traffic information service can be provided.

Claims

1. A method for providing a location-based traffic information service, comprising:

receiving a traffic message indicating a traffic condition;

determining a traffic information service station matching the traffic information in terms of location; and

dispatching the traffic message to the matched traffic information service station, such that the traffic message is broadcasted within a service range of the matched traffic information service station.

2. The method according to claim 1, wherein the determining a traffic information service station matching the traffic information in terms of location comprises:

extracting a keyword indicating a location from the traffic message;

calculating a distance between the location indicated by the keyword and a location of at least one traffic information service station; and

selecting a traffic information service station that minimizes the distance as the traffic information service station matching the traffic message.

3. The method according to claim 1, wherein the determining a traffic information service station matching the traffic information comprises:

extracting a keyword indicating a location from the traffic message;

calculating a distance between the location indicated by the keyword and a location of at least one traffic information service station; and

selecting a traffic information service station with the distance smaller than a predetermined threshold as the traffic information service station matching the traffic message.

4. The method according to claim 1, wherein the traffic message is a text message, and wherein the dispatching the traffic message to the matched traffic information service station comprises:

converting the text message into a speech message; and

transmitting the speech message to the matched traffic information service station.

5. The method according to claim 1, wherein the traffic message is a text message, and wherein the dispatching the traffic message to the matched traffic information service station comprises:

transmitting the text message to the matched traffic information service station.

6. The method according to claim 1, wherein the traffic message is broadcasted by the traffic information service station using a radio communication.

7. The method according to claim 6, wherein the traffic information service station uses a same radio frequency as another traffic information service station.

8. The method according to claim 6, wherein the traffic information service station uses a different radio frequency from another traffic information service station.

9. The method according to claim 1, wherein the traffic information service station uses a different radio frequency from another traffic information service station.

10. The method according to claim 1, wherein the traffic information service station has a service range that overlaps with that of another traffic information service station.
