System and method for determining recommended departure time
View Patent ↗The present invention provides a system and method for determining the necessary departure time to allow for an on-time or desired arrival time at a particular location over a particular route based on the evaluation of historic, present, and predicted road conditions.
1. A system comprising:
a data aggregation server configured to manage a plurality of data sets;
a road speed prediction engine stored in memory and executable to generate a prediction of average speed based on the plurality of data sets, the prediction of average speed including a long-term prediction of average speed; and
a routing engine stored in memory and executable to calculate a departure time based on at least the prediction of average speed.
2. The system of claim 1 wherein the plurality of data sets comprises at least delayed batch traffic data.
3. The system of claim 2 wherein the delayed batch traffic data comprises at least traffic data pertaining to historically observed road speeds.
4. The system of claim 2 wherein the delayed batch traffic data comprises at least traffic data pertaining to special events.
5. The system of claim 4 wherein the at least traffic data pertaining to special events comprises manual-entry data.
6. The system of claim 1 wherein the plurality of data sets comprises at least real-time traffic data.
7. The system of claim 6 wherein the real-time traffic data comprises manual- entry data.
8. The system of claim 6 wherein the real-time traffic data comprises automated-entry data.
9. The system of claim 1 wherein the prediction of average speed is generated by the road speed prediction engine through recognition of repeating traffic patterns.
10. The system of claim 1 wherein the prediction of average speed is generated by the road speed prediction engine through extrapolation from real-time traffic patterns.
11. The system of claim 1 wherein the prediction of average speed represents a short-term prediction of average speed.
12. A method comprising:
executing instructions stored in memory to aggregate a plurality of data sets;
executing instructions stored in memory to generate a prediction of average speed for a segment of roadway based on the plurality of data sets, the prediction of average speed including a long-term prediction of average speed; and
executing instructions stored in memory to calculate a departure time based on at least the prediction of average speed for the segment of roadway.
13. The method of claim 12 wherein the plurality of data sets comprises at least delayed batch traffic data.
14. The method of claim 12 wherein the plurality of data sets comprises at least real-time traffic data.
15. The method of claim 13 wherein the delayed batch traffic data comprises at least traffic data pertaining to historically observed road speeds.
16. The method of claim 12 wherein the delayed batch traffic data comprises at least traffic data pertaining to special events.
17. The method of claim 13 wherein the real-time traffic data is manual-entry data.
18. The method of claim 13 wherein the real-time traffic data is automated- entry data.
19. The method of claim 11 wherein the prediction of average speed is generated by a road speed prediction engine through recognition of repeating traffic patterns.
20. The method of claim 11 wherein the prediction of average speed is generated by a road speed prediction engine through extrapolation from real-time traffic patterns.
21. The method of claim 11 wherein the prediction of average speed represents a short-term prediction of average speed.
22. A computer readable storage medium having embodied thereon a program being executable by a machine to perform a method comprising:
aggregating a plurality of data sets;
generating a prediction of average speed for a segment of roadway based on the plurality of data sets, the prediction of average speed including a long-term prediction of average speed; and
calculating a departure time based on at least the prediction of average speed for the segment of roadway.
23. The computer readable storage medium of claim 22 wherein the prediction of average speed is generated through recognition of repeating traffic patterns.
24. The computer readable storage medium of claim 22 wherein the prediction of average speed is generated through extrapolation from real-time traffic patterns.
