A route finding system has a map database containing node data and edge data, wherein nodes represent points on a route and edges represent the connections between the nodes. A route search system determining an optimal route according to prescribed route parameters, wherein a route comprises at least one partial route, and a partial route comprises at least one edge, considers the difficulty of the partial routes during route finding. The abilities of the user and/or a user selection determine the influence of the difficulty of the partial routes on the route obtained during route search. Difficult partial routes are characterized by the necessity of carrying out difficult maneuvers, particularly turning maneuvers and/or crossing maneuvers, to complete the partial route.
