Abstract

Claims (38)

1. A computer-implemented method for generating a weather index mapped to a road segment for a particular time frame, comprising:

(a) receiving weather condition information for a plurality of time periods, the weather condition information including historical data corresponding to the road segment and forecasted weather information corresponding to the road segment;

(b) parsing the weather condition information to determine, for each of the plurality of time periods, weather conditions for the road segment defined by a starting point and an ending point; and

(c) generating, for each of the plurality of time periods, at least one weather index corresponding to the road segment, each weather index representing the predicted impact on traffic for the road segment for the respective time period, the predicted impact on traffic based at least in part on the historical data, wherein the plurality of time periods includes at least one future time period.

2. The method of claim 1 , wherein each predicted impact on traffic is based on historical data particular to the road segment for which the weather index is being generated.

3. The method of claim 1 , further comprising:

generating a travel route associated with a travel time, the travel route including a plurality of road segments and a weather index for the plurality of road segments, wherein each weather index is representative of the weather index that will be in effect for the corresponding road segment based on the travel route and arrival time.

4. The method of claim 3 , wherein the arrival time for each particular road segment is determined based on the weather indices of the road segments previously scheduled along the travel route.

5. The method of claim 1 , further comprising:

representing the weather conditions using indicia selected from the group of weather presentation formats consisting of weather condition color contours and weather condition icons.

6. The method of claim 5 , further comprising:

representing the impact on traffic using indicia selected from the group of traffic presentation formats consisting of colors indicating travel speeds along the defined travel route and traffic affecting condition icons.

7. The method of claim 1 , wherein the weather index generated for any particular road segment is calculated based on the highest predicted traffic impact anywhere along the road segment.

8. The method of claim 1 , wherein the starting point and ending point of a road segment are provided as a longitude and latitude value.

9. The method of claim 1 , wherein the weather condition information is filtered and the at least one weather index is calculated based on the filtered weather condition information to generate an application specific weather index.

10. The method of claim 9 , further including

generating a snow plowing equipment allocation schedule based on the application specific weather index.

11. A computer-implemented system for generating a weather index mapped to a road segment for a particular time frame, comprising:

(a) a weather condition information source configured to generate weather condition information for a plurality of time periods, the weather condition information including historical data corresponding to the road segment and forecasted weather information corresponding to the road segment;

(b) a road segment database including a plurality of road segments, each segment defined by a starting point and an ending point;

(c) a weather mapping application configured to parse the weather condition information to determine, for each of the plurality of time periods, weather conditions for the road segments in the road segment database; and

(d) a weather index generator configured to generate, for each of the plurality of time periods, at least one weather index corresponding to each road segment, each weather index representing the predicted impact on traffic for the road segment for the respective time period, the predicted impact on traffic based at least in part on the historical data, wherein the plurality of time periods includes at least one future time period.

12. The system of claim 11 , wherein each predicted impact on traffic is based on historical data particular to the road segment for which the weather index is being generated.

13. The system of claim 11 , further comprising a travel route generator configured to generate a travel route associated with a travel time, the travel route including a plurality of road segments and a weather index for the plurality of road segments, wherein each weather index is representative of the weather index that will be in effect for the corresponding road segment based on the travel route and arrival time.

14. The system of claim 13 , wherein the arrival time for each particular road segment is determined based on the weather indices of the road segments previously scheduled along the travel route.

15. The system of claim 11 , wherein the weather index generated for any particular road segment is calculated based on the highest predicted traffic impact anywhere along the road segment.

16. The system of claim 11 , wherein the weather conditions are represented using indicia selected from the group of weather presentation formats consisting of weather condition color contours and weather condition icons.

17. The system of claim 16 , wherein the impact on traffic are represented using indicia selected from the group of traffic presentation formats consisting of colors indicating travel speeds along the defined travel route and traffic affecting condition icons.

18. The system of claim 11 , wherein the starting point and ending point of a road segment are provided as a longitude and latitude value.

19. The system of claim 11 , wherein the weather condition information is filtered and the at least one weather index is calculated based on the filtered weather condition information to generate an application specific weather index.

20. The system of claim 19 , further including generating a snow plowing equipment allocation schedule based on the application specific weather index.

21. A computer-implemented method for generating a weather index mapped to a road segment for a particular time frame, comprising:

(a) receiving weather condition information for a plurality of time periods, the weather condition information including historical data corresponding to the road segment and forecasted weather information corresponding to the road segment;

(b) parsing the weather condition information to determine, for each of the plurality of time periods, weather conditions for the road segment defined by a starting point and an ending point;

(c) generating, for each of the plurality of time periods, at least one weather index corresponding to the road segment, each weather index representing the predicted impact on traffic for the road segment or the respective time period, the predicted impact on traffic based at least in part on the historical data;

(d) generating a preliminary travel route including a plurality of road segments, each of the road segments having an arrival time;

(e) providing one of the weather indices for each road segment based on the preliminary travel route and arrival time for each road segment, wherein the predicted arrival time for each particular road segment is determined based on the weather indices of the road segments previously scheduled along the travel route; and

(f) modifying the preliminary travel route based on the provided weather indices to generate at least one additional travel route.
