Abstract

Embodiments described herein may provide a method for providing a local hazard warning to vehicles or devices at locations near an observed weather condition. Methods may include: receiving an indication of an observed weather condition from a probe; receiving an indication of a location of the observed weather condition from the probe; generating an estimation of a local hazard at a plurality of locations proximate the location of the observed weather condition; generating a confidence level of the local hazard at each of the plurality of locations proximate the location of the observed weather condition; and generating a local hazard warning for at least one of the plurality of locations in response to the confidence level for the at least one of the plurality of locations satisfying a predefined measure.

Claims

1. An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to at least:

receive an indication of an observed weather condition from a probe;

receive an indication of a location of the observed weather condition from the probe;

generate an estimation of a local hazard relating to the observed weather conditions at a plurality of locations proximate the location of the observed weather condition;

determine a distance of each of the plurality of locations from the location of the observed weather condition;

determine an elapsed time since the observed weather condition was observed;

generate a confidence level of the local hazard at each of the plurality of locations proximate the location of the observed weather condition, wherein the confidence level of the local hazard at each of the plurality of locations is calculated using an inverse ratio of the distance of each respective location of the plurality of locations from the location of the observed weather condition and an inverse ratio of the elapsed time since the weather condition was observed such that the time and distance are inversely proportional to the confidence level; and

generate a local hazard warning for at least one of the plurality of locations in response to the confidence level for the at least one of the plurality of locations satisfying a predefined measure.

2. The apparatus of claim 1, wherein each of the plurality of locations comprises a reference location for a geographic area, and wherein causing the apparatus to generate a local hazard warning for at least one of the plurality of locations comprises causing the apparatus to:

provide a local hazard warning to at least one vehicle located within at least one of the plurality of locations having a confidence level satisfying the predefined measure.

3. The apparatus of claim 2, wherein causing the apparatus to provide a local hazard warning to at least one vehicle comprises causing the apparatus to:

provide a local hazard warning for presentation to a user of the vehicle on a user interface of the vehicle.

4. The apparatus of claim 1, wherein the apparatus is further configured to:

generate an estimation of intensity of a weather condition at each of the plurality of locations proximate the location of the observed weather condition.

5. The apparatus of claim 4, wherein causing the apparatus to generate the estimation of intensity of a weather condition at each of the plurality of locations comprises causing the apparatus to:

receive weather radar imagery comprising each of the plurality of locations; and

determine, for each of the plurality of locations, an estimation of intensity of a weather condition based on the weather radar imagery corresponding to the respective location.

6. The apparatus of claim 1, wherein the indication of a weather condition from the probe comprises an indication of rain or fog at the location of the probe.

7. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions to:

receive an indication of an observed weather condition from a probe;

receive an indication of a location of the observed weather condition from the probe;

generate an estimation of a local hazard at a plurality of locations proximate the location of the observed weather condition;

determine a distance of each of the plurality of locations from the location of the observed weather condition;

determine an elapsed time since the observed weather condition was observed;

generate a confidence level of the local hazard at each of the plurality of locations proximate the location of the observed weather condition, wherein the confidence level of the local hazard at each of the plurality of locations is calculated using an inverse ratio of the a distance of each respective location of the plurality of locations from the location of the observed weather condition and an inverse ratio of the elapsed time since the weather condition was observed such that the time and distance are inversely proportional to the confidence level; and

generate a local hazard warning for at least one of the plurality of locations in response to the confidence level for the at least one of the plurality of locations satisfying a predefined measure.

8. The computer program product of claim 7, wherein each of the plurality of locations comprises a reference location for a geographic area, and wherein the program code instructions to generate a local hazard warning for at least one of the plurality of locations comprises program code instructions to:

provide a local hazard warning to at least one vehicle located within at least one of the plurality of locations having a confidence level satisfying the predefined measure.

9. The computer program product of claim 8, wherein the program code instructions to provide a local hazard warning to at least one vehicle comprises program code instructions to:

provide a local hazard warning for presentation to a user of the vehicle on a user interface of the vehicle.

10. The computer program product of claim 8, further comprising program code instructions configured to:

generate an estimation of intensity of a weather condition at each of the plurality of locations proximate the location of the observed weather condition.

11. The computer program product of claim 10, wherein the program code instructions to generate the estimation of intensity of a weather condition at each of the plurality of locations comprises program code instructions to:

receive weather radar imagery comprising each of the plurality of locations; and

determine, for each of the plurality of locations, an estimation of intensity of a weather condition based on the weather radar imagery corresponding to the respective location.

12. The computer program product of claim 7, wherein the indication of a weather condition from the probe comprises an indication of rain or fog at the location of the probe.

13. A method comprising:

receiving an indication of an observed weather condition from a probe;

receiving an indication of a location of the observed weather condition from the probe;

generating an estimation of a local hazard at a plurality of locations proximate the location of the observed weather condition;

determining a distance of each of the plurality of locations from the location of the observed weather condition;

determining an elapsed time since the observed weather condition was observed;

generating a confidence level of the local hazard at each of the plurality of locations proximate the location of the observed weather condition, wherein the confidence level of the local hazard at each of the plurality of locations is calculated using an inverse ratio of the a distance of each respective location of the plurality of locations from the location of the observed weather condition and an inverse ratio of the elapsed time since the observed weather condition was observed such that the time and distance are inversely proportional to the confidence level; and

generating a local hazard warning for at least one of the plurality of locations in response to the confidence level for the at least one of the plurality of locations satisfying a predefined measure.

14. The method of claim 13, wherein each of the plurality of locations comprises a reference location for a geographic area, and wherein generating a local hazard warning for at least one of the plurality of locations comprises:
