Abstract

A navigational method and a navigational system for determining a route from a starting location to a destination location for a means of locomotion, especially for a motor vehicle, an airplane, or a ship, the route being calculated on the basis of a digital database, which contains predetermined path segments Wi having correspondingly assigned nodal points Ni, which connect the specific path segments Wi to each other, the specific weightings Gi being assigned to the path segments Wi and/or to the nodal points Ni. In this context, the weightings Gi that are used for the route calculation are varied as a function of the time of day.
