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).
