Abstract: The present invention pertains to a method for generating a digital roadmap that can be stored on an electronic storage medium and in which a geographical area is specified by a multitude of data sets. The present invention further pertains to a navigation system that features a memory on which a digital roadmap of this type is stored and provided for use. Moreover, the present invention pertains to a method for operating a navigation system of the afore-mentioned type with a digital roadmap of the afore-mentioned type.

Abstract: The present invention relates to a method for determining the estimated time of travel and time of arrival in the route determination on a digital road map by means of a speed table and by means of measured user speeds. Moreover, the present invention relates to a corresponding computer program product and to a digital storage medium as well as to a corresponding navigation device. The present invention is characterized by the feature that the speed table is classified into temporal classes (k, l, m, n) for at least one, preferably for each road category (B), wherein one temporal class is respectively allocated separate average speeds as a function of the weekday and/or the time of day (A).
