A system method and device for predicting navigational decision-making behavior is provided. The location of a device is used to generate the current location of the device, and a history of past locations of the device. A behavior predicting application predicts the route a drive is going to travel based on driver preferences, such as left-hand turns, avoidance of bridges, etc., as well as the preferred destinations and/or routes traveled in the past. The preferences of a particular driver can be learned by the system to be implemented in the behavior predicting application, or manually input by the driver. The system can employ GPS or other positioning technology to determine the location of the device. The device can be a standard GPS-enabled in-car device, or other portable device such as a cell phone or PDA.
