ENHANCEMENT FOR NAVIGATION SYSTEMS FOR USING WEATHER INFORMATION WHEN PREDICTING A QUICKEST TRAVEL PATH

摘要

The present invention discloses a software method for determining a travel path. The software method can identify a point of origin, a travel destination, and a travel time. Multiple different possible travel pathways between the point of origin and the travel destination can be determined. Predicted weather conditions for each of the travel pathways for a time of travel can be ascertained. Time estimates for each of the travel pathways can be adjusted based on the predicated weather conditions for each of the travel pathways. At least one of the determined travel pathways can be presented based at least in part upon the time estimates that have been adjusted for the predicted weather conditions and historical data about the given pathways with similar weather to that which is being predicted. In one embodiment; the software method can be performed by a Global Positioning System (GPS) equipped motor vehicle navigation system.
