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. The method can be carried out advantageously by the use of a cellular mobile wireless system (10), wherein the starting point (A) and the end point (E) are each formed by corresponding cells (12, 13) of the mobile wireless system (10). The determination of the travel time results from the data of the mobile wireless system (10).

a) specific pieces of information of at least one mobile user end device located at a starting point (A) are determined and each is linked to a time marker (TA);

b) specific pieces of information of at least one mobile user end device located at the end point (E) are determined and each is linked to a time marker (TE);

c) the specific pieces of information of the at least one mobile user end device located at the starting point (A) and at the end point (E) are compared with one another electronically in at least one central processing unit; and

d) when there is agreement between the specific pieces of information of a mobile user end device at the starting point (A) and at the end point (E), the time difference (TE−

TA) between the time marker (TE) and the time marker (TA) is formed and the travel time is determined from it electronically in the central processing unit.

2. The method according to claim 1, further characterized in that this is carried out by use of an information transmitting system, in particular a communication system, whereby the travel time is determined from specific data of the mobile user end devices of the information transmitting system.

4. The method according to claim 1, further characterized in that specific pieces of information of all mobile user end devices located at the starting point (A) and/or the end point (E) are determined and furnished with a corresponding time marker (TA, TE).

5. The method according to claim 1, further characterized in that the specific pieces of information of the at least one mobile user end device located at the starting point (A) and at the end point (E) are transmitted to the central processing unit or are generated electronically in the central processing unit.

6. The method according to claim 1, further characterized in that the starting point (A) and/or the end point (E) is fixed in the form of a geographical value.

9. The method according to claim 1, further characterized in that an action profile is determined for the at least one mobile user end device at the starting point (A) and/or for the at least one mobile user end device at the end point (E) from specific pieces of information for these and that each action profile is linked to a time marker (TA, TE).

10. The method according to claim 9, further characterized in that the action profile is determined in the mobile user end device associated therewith or in the central processing unit.

11. The method according to claim 1, further characterized in that the central unit has at least one computing unit with one or more electronic computers and that the travel time is determined electronically in the at least one computing unit.

12. The method according to claim 1, further characterized in that the time marker-linked, specific pieces of information or action profiles of each mobile user end device and/or the travel times determined therefrom are filed in the form of comparison data at least temporarily in a comparison file.

13. The method according to claim 12, further characterized in that the comparison data are subjected to a weighting step in the central processing unit.

14. The method according to claim 12, further characterized in that, in the central unit, a geographical and/or user-specific assignment is generated on the basis of the comparison data.

15. The method according to claim 1, further characterized in that the time marker-linked, specific pieces of information or action profiles of each mobile user end device and/or the travel times determined therefrom and/or the comparison data generated therefrom are compared with corresponding reference values within the central processing unit.

16. The method according to claim 1, further characterized in that the travel time is determined in a continual manner and in that the travel time is updated in a continual manner.

18. The method according to claim 17, further characterized in that the individual travel times of the distance segments (S) are determined in a continual manner and in that the total travel time is updated in a continual manner on the basis of the travel times within the distance segments (S).

20. The method according to claim 1, further characterized in that the time marker-linked, specific pieces of information or action profiles of each mobile user end device and/or the travel times determined therefrom and/or the comparison data generated therefrom and/or the total travel times determined and/or the traffic information generated are transmitted from the central processing unit to selected or to all mobile user end devices.
