System and Methods For Providing Predictive Traffic Information
First Claim
1. A method for providing predictive traffic information to global positioning satellite systems on board vehicles, comprising:
- a plurality of GPS-enabled vehicles, each estimating at least one travel route comprising a plurality of road segments and estimating arrival and exit times for the vehicle in each road segment;
calculating an initial road capacity for each road segment;
statistically polling a plurality of GPS-enabled vehicles;
obtaining at least one of at least one static parameter, at least one dynamic parameter, or at least one catastrophic condition relating to the at least one travel route; and
calculating predictive capacity estimates for each road segment for at least one future time interval.

17. A method for providing predictive traffic information to global positioning satellite systems on board vehicles, comprising:
-
a plurality of GPS-enabled vehicles, each estimating at least one travel route comprising a plurality of road segments and estimating arrival and exit times for each road segment; calculating an initial road capacity for each road segment based on the estimated arrival and exit times for each road segment and at least one of posted speed limits, traffic signs, or traffic lights; updating the initial road capacity estimates based on at least one of traffic flow conditions or weather conditions; statistically polling the plurality of GPS-enabled vehicles, each vehicle providing the at least one travel route and estimated arrival and exit times for each road segment; calculating predictive capacity estimates for each road segment for at least one future interval based on said updated road capacity estimates and said statistical polling; sending the predictive capacity estimates for at least one future time interval to a plurality of GPS-enabled vehicles; and said GPS-enabled vehicles re-calculating the at least one travel route and the arrival and exit times for each road segment.
