Disclosed is a method for providing navigation instructions to a user for reaching a destination via a route planned on a map of a navigation system, said map comprising a plurality of road segments, at least a subset of which comprise an assigned familiarity score. The method comprises tracking a route taken by a user; calculating an updated familiarity score of the road segments of the tracked route using at least one of a user-defined updating variable and an updating variable based on at least one dynamically obtained actual travelling condition; and storing the updated familiarity score in a data storage of the navigation system. The user-defined update variable may express the learning ability of the user to become familiar with an unknown route, while the dynamically obtained travelling conditions may relate to weather, road or traffic conditions. Based on the familiarity score the user may then receive fewer navigation instructions when travelling on familiar routes. |
