US Patent 8150611 System and methods for providing predictive traffic information

A method for providing predictive traffic information to global positioning satellite systems on board vehicles includes 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.
