Abstract
The described method and system provide for GPS navigation utilizing variable route corridors. The method may be implemented at a GPS-capable device (e.g. a telematics unit in one implementation) or through a call center that provides navigation services to a telecommunications device (e.g. a telematics unit in another implementation). A user input corresponding to an intended destination is received and a route to the intended destination is calculated with a variable route corridor. The variable route corridor is calculated based on map features, such as other streets not on the route, the width of streets on the route, and map data inaccuracies. In preferred implementations, the system and method are implemented within the context of a GPS unit that is part of a telematics unit in a vehicle.
