Abstract

A method for notifying a mobile body that the mobile body is approaching a particular area comprising calculating a plurality of areas where the mobile body may arrive on the basis of dynamic map information; calculating, for each event occurring in the plurality of areas, an arriving probability of arriving at a region affected by the event; extracting an avoidance position for enabling the mobile body to avoid arriving at the region affected by the event; calculating an encountering probability of meeting the region affected by the event on the basis of a reliability of the event, the arriving probability, and the avoidance position, and notifying the mobile body of the encountering probability.

Claims

1. A method comprising:

calculating a plurality of areas where a mobile body may arrive on a basis of dynamic map information;

calculating, for an event occurring in the plurality of areas, an arriving probability of arriving at a region affected by the event;

extracting an avoidance position for enabling the mobile body to avoid arriving at the region affected by the event;

calculating an encountering probability of meeting the region affected by the event on a basis of a reliability of the event, an arriving probability, and an avoidance position; and

notifying the mobile body of the encountering probability.

2. The method of claim 1, wherein the reliability of the event is calculated on a basis of an information source of the event, a frequency of reporting the same event, or a combination of the information source and the frequency.

3. The method of claim 2, wherein the reliability of the event is weighted according to the information source of the event while being calculated.

4. The method of claim 3, wherein the reliability of the event is set so as to be calculated higher when the information source of the event is a public or private institution than when the information source of the event is the mobile body.

5. The method of claim 2, wherein the reporting of the event is done via a plurality of mobile bodies or a plurality of sensors.

6. The method of claim 2, wherein the reliability of the event is set so as to be calculated higher as the frequency of reporting the same event becomes higher.

7. The method of claim 1, further comprising:

collecting events; and

incrementing the reliability of an event when the same event is collected.

8. The method of claim 1, wherein the event corresponds to any of sensor information, image or movie information from the mobile body, various kinds of sensor information, weather information, disaster information, traffic control information, traffic regulation information, traffic jam information, construction information, traffic accident information, road surface information, parking information, images, or movies from sensors, or special occasion information.

9. The method of claim 1, wherein calculating a plurality of areas comprises creating an event notification range for notifying the mobile body of the event.

10. The method of claim 9, wherein the event notification ranges changes in accordance with the reliability of the event.

11. The method of claim 9, wherein calculating a plurality of areas comprises connecting reachable points of the mobile body to create a mobile body notification range.

12. The method of claim 11, wherein calculating a plurality of areas comprises determining a closeness between the event notification range and the mobile body notification range to provide a plurality of areas where the mobile body may arrive.

13. The method according to claim 11, wherein calculating the encountering probability occurs in accordance with dynamic change of an overlapping region between the event notification range and the mobile body notification range.

14. The method according to claim 1, wherein the encountering probability is calculated with respect to a driving history of the mobile body.

15. The method of claim 1, wherein calculating the arrival probability comprises calculating an estimated arrival time of the mobile body to arrive at the region affected by the event.

16. The method of claim 15, wherein the encountering probability is calculated on the basis of the estimated arrival time in addition to the reliability of the event, the arriving probability, and the avoidance position.

17. The method according to claim 1, wherein notifying the mobile body of the encountering probability comprises further notifying the mobile body of a type of the event corresponding to the encountering probability.

18. The method according to claim 1, wherein notifying the mobile body of the encountering probability comprises further notifying the mobile body of a type of the event corresponding to the encountering probability.

19. A computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to;

calculate a plurality of areas where a mobile body may arrive on a basis of dynamic map information;

calculate, for an event occurring in the plurality of areas, an arriving probability of arriving at a region affected by the event;

extract an avoidance position for enabling the mobile body to avoid arriving at the region affected by the event;

calculate an encountering probability of meeting the region affected by the event on a basis of a reliability of the event, an arriving probability, and an avoidance position; and

notify the mobile body of the encountering probability.

20. A computer system comprising:

one or more computer processors;

one or more computer-readable storage media;

program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising instructions to;

calculate a plurality of areas where a mobile body may arrive on a basis of dynamic map information;

calculate, for an event occurring in the plurality of areas, an arriving probability of arriving at a region affected by the event;

extract an avoidance position for enabling the mobile body to avoid arriving at the region affected by the event;

calculate an encountering probability of meeting the region affected by the event on a basis of a reliability of the event, an arriving probability, and an avoidance position; and

notify the mobile body of the encountering probability.
