Abstract:
A navigational system for determining a route from a starting location to a destination location for a locomotion device, comprising:an arrangement for providing a digital map base for calculating the route, the digital map base including predetermined path segments Wi having correspondingly assigned nodal points Ni that connect the predetermined path segments Wi to each other; and an arrangement for assigning specific weightings Gi to at least one of the predetermined path segments Wi and the nodal points Ni, wherein: the specific weightings Gi vary as a function of a time of day, and the specific weightings Gi correspond to a product of Gi=Li*Ki, Li being a path segment length, and Ki being a path segment class Ki that is inversely proportional to an average speed that is possible on one of the predetermined path segments Wi.
