A method for navigating with a vehicle navigation system using recognition of geographical region types in a map database. The system's map database stores information representative of a plurality of geographical region types. A geographical region type of a geographical region in which the navigation algorithm is operating is determined. At least one parameter related to the navigation algorithm is then set to correspond to the geographical region type. Navigation is performed using the navigation algorithm. Throughout the operation of the navigation algorithm, the system repeatedly determines whether the geographical region type has changed, and if so, changes the algorithm parameter(s) to correspond to the new geographical region type.

[ What is claimed is:] [1.] A method for navigating using a vehicle navigation system having a map database, the map database having information stored therein which is representative of a plurality of geographical region types, the vehicle navigation system employing a navigation algorithm, the method comprising the steps of:(A) determining a geographical region type of a geographical region in which the navigation algorithm is currently operating;(B) setting a first parameter related to the navigation algorithm to correspond to the geographical region type;(C) navigating using the navigation algorithm with the first parameter;(D) determining whether the geographical region type has changed to a different geographical region type;(E) changing the first parameter to correspond to the different geographical region type if the geographical region type has changed; and(F) repeating steps (C)-(E) while the navigation algorithm is operating.
