Abstract:
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 based on the at least one travel route, the estimated arrival and exit times for each road segment, and at least one static parameter; updating the initial road capacity estimates for each road segment based on at least one of at least one dynamic parameter or at least one catastrophic condition relating to the at least one travel route; statistically polling a plurality of GPS-enabled vehicles, wherein said statistically polling comprises data including a number of vehicles on at least one travel route in a given geographic region and the time estimates for when each vehicle will arrive and exit each road segment of the at least one travel route; and calculating predictive capacity estimates for each road segment for at least one future time interval based on said statistically polling and the updated road capacity estimates.
