US Patent 10274328 Generating personalized routes with route deviation information

A navigation device may include one or more input devices, a processor, and one or more output devices. A navigation device may read stored map information and stored route deviation information including one or more deviation segments having a divergence location, a deviation path, a reconvergence location, and deviation segment data. The processor of the navigation device may then generate a route and route data. Upon determining that each of the one or more deviation segments intersects the route and a predetermined subset of the deviation segment data matches a corresponding subset of the route data, the navigation device may generate a personalized route by replacing a route portion between a first intersection point and a last intersection point with a corresponding deviation portion for each intersecting deviation segment. The one or more output devices may then output the route and the one or more personalized routes.
