Abstract: A method as well as a system are described for determining the travel time of at least one mobile user end device between a starting point (A) and an end point (E) that is spatially separated from it. To this end, specific pieces of information of at least one mobile user end device located at the starting point (A) and at the end point (E) are determined and each linked to a time marker. The specific pieces of information of the mobile user end devices are compared with one another electronically in at least one central processing unit. When the specific pieces of information of a mobile user end device are in agreement at the starting point (A) as well as at the end point (E), the time difference between the time markers is formed electronically in the central processing unit and the travel times are determined therefrom.

Abstract: The invention relates to a method for acquiring traffic situation data in a network of traffic routes which is covered by a cellular mobile radio network comprising a multiplicity of base stations and in which a multiplicity of vehicles is moving which are in each case provided with an operating mobile terminal for the mobile radio network. In this method, characteristic patterns of values (called signal transit times in the text which follows), which are representative of the signal transit times with respect to the respective base station during the movement of a terminal along the course of the respective traffic route, are determined and permanently stored at least for some of the individual traffic routes of the network of traffic routes at least for selected base stations, the respective characteristic pattern or a sequence of values representative of this pattern is mapped onto the course of the respective traffic route (calibration).

Abstract: The invention relates to a method for detecting travel information in a traffic network covered by a cellular mobile radio network with a plurality of base stations provided with a clear identifier and wherein a plurality of vehicles move, said vehicles being respectively provided with an operating mobile terminal for the mobile radio network. Information on the contact between the end terminals and the base stations is used to estimate the location of the terminals. At least for one part of the traffic network, wherein the base stations have a transmission range with a cell radius corresponding to the distance separating neighboring traffic routes, characteristic models are determined in the form of sequences of identifiers of said base stations with which a terminal respectively enters into contact when it is displaced along a route, allocated to the respective route and permanently stored.
