Abstract

A method for selectively providing traffic information to a user without requiring the user to constantly monitor radio broadcasts is disclosed. The method comprises the steps of: determining at least one area of interest including a plurality of latitudinal and longitudinal coordinates; receiving traffic data including information related to a plurality of traffic events; parsing the traffic data for any of the traffic events located within at least one area of interest; and outputting a traffic event message to an output device if the latitudinal and longitudinal location of the related traffic event is located within the at least one area of interest.

Claims

1. A method for providing a user with traffic information, the method comprising the steps of:

determining at least one area of interest including a plurality of latitudinal and longitudinal coordinates;

receiving traffic data including information related to a plurality of traffic events;

parsing the traffic data for any of the traffic events located within at least one area of interest; and

outputting a traffic event message to an output device if the latitudinal and longitudinal location of the related traffic event is located within the at least one area of interest.

2. The method according to claim 1, wherein each of the traffic events includes at least one of a traffic incident located within the area of interest, a plurality of adjacent road segments located within the area of interest that are affected by the traffic incident, and any affected road segments located within the area of interest that are affected by a traffic incident that is located outside the area of interest.

3. The method according to claim 1, further comprising the steps of:

converting the traffic data to an audio traffic event message; and

outputting the audio traffic event message to the output device.

4. The method according to claim 1, wherein the step of determining at least one area of interest further comprises the steps of:

receiving a set of location readings taken at periodic intervals;

determining a travel direction by comparing the latitudinal and longitudinal changes among the set of readings first; and

defining the at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel direction,

5. The method according to claim 1, wherein the step of determining at least one area of interest further comprises the steps of:

receiving a plurality of locations of the user;

determining a travel route by comparing the plurality of locations of the user; and

defining the at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel route.

6. The method according to claim 1, further comprising the steps of:

determining if the traffic event message has been previously outputted to the output device; and

outputting the traffic event message to the output device if the traffic event has not been previously outputted to the output device.

7. The method according to claim 1, wherein the traffic data is received from a RDS-TMC signal coded in accordance with the Alert-C protocol.

8. The method according to claim 1, wherein the traffic data includes at least one of an event description, a location, a direction and extent, a duration, and a diversion advice.

9. The method according to claim 1, further comprising the steps of:

determining a priority level of each of the traffic events within the at least one area of interest;

comparing the priority level of each of the traffic events within the at least one area of interest with a user-selected priority level; and

filtering the traffic events to remove any traffic event that does not meet the user-selected priority level.

10. A method for providing a user with traffic information, the method comprising the steps of:

determining at least one area of interest including a plurality of latitudinal and longitudinal coordinates;

receiving a traffic data including information related to a plurality of traffic events;

parsing the traffic data for any of the traffic events located within at least one area of interest;

determining a priority level of each of the traffic events within the at least one area of interest;

comparing the priority level of each of the traffic events within the at least one area of interest with a user-selected priority level;

filtering the traffic events to remove any traffic event that does not meet the user-selected priority level; and

outputting a traffic event message to an output device if the latitudinal and longitudinal location of the related traffic event is located within the at least one area of interest.

11. The method of claim 10, further comprising the steps of:

converting the traffic message to an audio traffic event alert; and

outputting the audio traffic event message to the output device.

12. The method of claim 10, wherein the step of determining at least one area of interest further comprises the steps of:

receiving a set of location readings taken at periodic intervals;

determining a travel direction by comparing the latitudinal and longitudinal changes among the set of readings first; and

defining the at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel direction.

13. The method of claim 10, wherein the step of determining at least one area of interest further comprises the steps of:

receiving a plurality of locations of the user;

determining a travel route by comparing the locations of the user; and

defining the at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel route.

14. The method of claim 10, further comprising the steps of:

determining if the traffic message has been previously outputted to the output device; and

outputting the traffic message to the output device if the traffic event has not been previously outputted to the output device.

15. The method according to claim 10, wherein the traffic data is received from a RDS-TMC signal coded in accordance with the Alert-C protocol.

16. The method according to claim 10, wherein the traffic data includes at least one of an event description, a location, a direction and extent, a duration, and a diversion advice.

17. The method according to claim 10, wherein each of the traffic events includes at least one of a traffic incident located within the at least one area of interest, a plurality of adjacent road segments located within the at least one area of interest that are affected by the traffic incident, and any affected road segments located within the at least one area of interest that are affected by a traffic incident that is located outside the at least one area of interest.

18. In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for enabling operation of a system for providing a user with traffic information, the storage medium comprising instructions for:

determining at least one area of interest including a plurality of latitudinal and longitudinal coordinates;

receiving a traffic data including information related to a plurality of traffic events;

parsing the traffic data for any of the traffic events located within the at least one area of interest;

determining a priority level of each of the traffic events within the at least one area of interest;

comparing the priority level of each of the traffic events within the at least one area of interest with a user-selected priority level;

filtering the traffic events to remove any traffic event that does not meet the user-selected priority level; and

outputting a traffic event message to an output device if the latitudinal and longitudinal location of the related traffic event is located within the at least one area of interest.

19. The instructions of claim 18, wherein the instruction for determining at least one area of interest further comprises instructions for:

receiving a set of location readings taken at periodic intervals;

determining a travel direction by comparing the latitudinal and longitudinal changes among the set of readings; and

defining the at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel direction.

20. The instructions of claim 18, wherein the instruction for determining at least one area of interest further comprises instructions for:

receiving a plurality of locations of the user;

determining a travel route by comparing the locations of the user; and

defining at least one area of interest as a plurality of latitudinal and longitudinal coordinates surrounding the travel route.
