Abstract

A method for vehicular communications and information reporting. First and second wireless Internet connections between respective first and second vehicles and a web-server are provided. First and second event information is transmitted, to the web-server, from the first and second vehicles. The first and second event information relates to the same event in visual range, respectively, of occupants of the first and second vehicles. The web server may transmit, to the first and second vehicles, confirmed event information derived from the first and second event information.

Claims

1. A method of communicating update information for a geographic location, the method comprising:

receiving, by a network server, a plurality of event notifications associated with an event from a plurality of first devices, each of the event notifications including geographic location information and importance information relating to the respective event notifications;

identifying at least two received event notifications having a common geographic location;

determining common update information based, at least in part, on the identified at least two event notifications;

calculating an importance score for the common update information based on the importance information corresponding to the at least two received event notifications;

generating an update message comprising the common update information and the importance score; and

transmitting, by the network server, the update message to one or more second devices.

2. The method of claim 1, wherein the geographic location information of each of the plurality of event notifications corresponds to the location of the respective first devices at the time the respective event notifications were composed.

3. The method of claim 2, wherein the determining common update information includes determining an estimated second geographic location for the common update information.

4. The method of claim 1, further comprising:

updating a reliability level associated with at least one of the plurality of first devices based at least in part on the determining the common update information; and

weighting subsequent communications from the at least one of the plurality of first devices based on the updated reliability level when calculating the importance score.

5. The method of claim 1, wherein the importance information is a ranking of the event.

6. The method of claim 1, wherein the importance information is a textual or graphical characterization of the event.

7. A system of communicating update information for a geographic location, the system comprising:

a network server configured for;

receiving a plurality of event notifications associated with an event from a plurality of first devices, each of the event notifications including geographic location information and importance information; and

transmitting an update message to one or more second devices;

a processor configured for;

identifying at least two received event notifications having a common geographic location;

determining common update information based, at least in part, on the identified at least two event notifications;

calculating an importance score for the common update information based on the importance information corresponding to the at least two received event notifications; and

generating the update message, the update message comprising the common update information and the importance score.

8. The system of claim 7, wherein the geographic location information of each of the plurality of event notifications corresponds to the location of the respective first devices at the time the respective event notifications were composed.

9. The system of claim 8, wherein the processor is further configured for estimating the common geographic location by processing the geographic location information corresponding to the at least two received event notifications.

10. The system of claim 7, wherein the processor is further configured for:

updating a reliability level associated with at least one of the plurality of first devices based at least in part on the determining the common update information; and

weighting subsequent communications from the at least one of the plurality of first devices based on the updated reliability level when calculating the importance score.

11. The system of claim 7, wherein the importance information is a ranking of the event.

12. The system of claim 7, wherein the importance information is a textual or graphical characterization of the event.

13. A method for communicating event updates associated with a first event, the method comprising:

receiving, by a network server, a first communication from a first device, the first communication comprising (i) first event information associated with the first event; and

(ii) first importance information relating to the first event information;

receiving, by the network server, a second communication from a second device, the second communication comprising (i) second event information associated with the first event; and

(ii) second importance information relating to the second event information;

determining common information for the first event from the first event information and the second event information;

generating an update message for the first event comprising the common information; and

transmitting, by the network server, the update message to one or more third devices.

14. The method of claim 13, wherein the common information comprises an average of the first importance information and the second importance information.

15. The method of claim 13, wherein the importance information is a ranking of the first event.

16. The method of claim 13, wherein the importance information is a textual or graphical characterization of the first event.

17. The method of claim of claim 13, wherein the first communication and the second communication include first and second location information associated with the first event.

18. The method of claim 17, further comprising:

receiving position information from the one or more third devices; and

determining that the position information relates to the first event based on a comparison with the first and second location information.

19. The method of claim 13, wherein the first event is a road condition.

20. The method of claim 19, wherein the road condition is a restaurant.
