摘要： The invention concerns a method for coding congestion affecting several traffic lanes, in the context of digitally coded traffic information containing, in the form of elements, a site located on a traffic lane, and the size and direction of the congestion. Said data are decoded by a look-up table of sites. The method is characterised in that when a congestion is announced extending by its size beyond a branch road onto another traffic lane, another element is used for coding the following data: branch roads affected by the congestion, direction and size of the congestion.

摘要： The invention relates to a method for operating a navigation system of a vehicle, especially a motor vehicle whereby, a route is calculated by means of a computing circuit based on the location of the vehicle, a digitally stored road map and a destination, and provided to the driver in the form of an acoustic and/or visual message, whereby a) information relating to the traffic situation of the route can be obtained via a receiver unit and a new travel time (t) resulting therefrom is calculated on the basis of a predetermined weighting factor (Gf) for a disruption and duration of a traffic disruption (Ls); b) a travel time (ta) for an alternative route is calculated in the same manner and if said travel time (ta) for the alternative route is shorter than the travel time (t) of the route, it is indicated to the driver. According to the invention, a correction value (K) for the weighting factors (Gf) is determined on the basis of the length of the traffic disruption (Ls). Depending on the correction value (Kw), a corrected weighting factor (Gk) is determined which is used to calculate a new travel time (t).

摘要： The invention relates to a method and to a receiver for geographical selection of digitally coded messages which are sent by several transmitters and contain local data which is compared in receivers with selection data according to the respective positions of the receivers so that the transmitters can also send selection data characterizing their respective transmitter range. Said data is compared in receivers with local data contained in the messages.

摘要： The invention relates to a method for calculating a route from a starting point to a destination. The method is characterised in that the route is calculated through at least one through target after at least one through destination has been predetermined, said through target being located within a radius of the at least one through destination that is predetermined by at least one predetermined criterion. In contrast to known route calculation methods from the prior art, the predetermined through targets are not actually part of the driving route but simply serve as roughly predetermined reference points up to a predetermined radius, for influencing the route calculation process.

摘要： The invention relates to a method for calculating routes in a vehicle navigation device, in which a route from a starting location or a current location to a target location is calculated. Said method provides that in the event of a vehicle defect or a problem affecting the vehicle driver, the route to an alternative target location which is preferably suitably equipped to eliminate the defect/problem is calculated instead of the target location. The invention also relates to a method for navigating a vehicle driver from a starting location to at least one target location, in which a travel route from the starting location or a current location to the at least one target location is determined and directions are produced according to a current location. This method provides that in the event of a vehicle defect or a problem affecting the vehicle driver, the travel route to an alternative target location which is preferably suitably equipped to eliminate the defect/problem is calculated. The inventive method relieves the vehicle driver of the task of finding suitable alternative locations in a separate street map and of the task of additionally inputting the alternative target location found as the new target location, for navigation to said alternative target location.

摘要： The invention relates to a method and arrays for the selection of traffic information services that can be received with at least one mobile receiver, said traffic information services being relevant to a route previously established by a navigation device connected to at least one receiver. According to said method, information on services for the established route is read from a stored list that identifies the services having traffic information that is relevant for said route. If several services are available, a chart is drawn containing the read service information that is sorted in accordance with an evaluation and that can be modified during tracking of said route. The receiver is set to the highest ranked service.
