Abstract
An on-board automobile navigation system provides advisory information to the driver based on real-time traffic information and a learned commute route. The system empirically determines a commute route based on historical travel data of the vehicle. The system further receives real-time traffic information via a wireless link. The real-time traffic information may include information relating to traffic accidents, construction, and other traffic problems and the locations of such problems. At power up, the system automatically determines whether the present day and time are within a previously defined commute time window and, if so, prompts the driver to accept or decline a previously defined commute destination. The system automatically receives the real-time traffic information and compares the location information associated with any traffic problems to the commute route. If the system determines that the location of a traffic problem falls on or near the commute route, then the system outputs an appropriate notification to the user and, if possible, computes an alternative route.
