Abstract
A method for operating a navigation system for a vehicle, particularly for a motor vehicle, in which a travel route is calculated in a computing circuit on the basis of a location of the vehicle, a digitally stored map and a destination location, and is made available to the vehicle driver as an acoustical and/or visual message, where traffic information relevant to the travel route may be acquired via a receiver unit and a new travel time t resulting therefrom is calculated for the existing travel route with the aid of a predefined weighting factor G for a disturbance event and the length of a traffic disturbance L , and a travel time t is calculated in the same manner for an alternative route, and in the event that the travel time t of the alternative route is shorter than the travel time t of the travel route, is indicated to the vehicle driver. A correction value K for the weighting factors G is ascertained on the basis of the length of the traffic disturbance L , and a corrected weighting factor G is ascertained as a function of the correction value K and is used for calculating the new travel time t.
