Abstract: A computer system for determining traffic patterns and congestion and using the determined traffic patterns and congestion to determine an appropriate route using a global positioning system and related route map calculator. A vehicle is provided with an onboard computer system adapted to determine travel time of a vehicle in a road segment and calculate a route based on this information. In addition, this information can be distributed to or otherwise shared with other vehicles and similar information can be received from other vehicles to provide a distributed network for generating and sharing experienced traffic patterns. The information can also be used to predict traffic patterns as well.
