A method for collecting transportation vehicle-based data and transferring the data to a backend computer, wherein the respective data sets relate to predefined route sections travelled along by a swarm of data-collecting vehicles, wherein parameterized orders for the acquisition of transportation vehicle-based data are stored in the backend computer and each order includes the parameter of route section, which defines the route section for which transportation vehicle-related data is to be collected; the parameter of swarm size, which defines how many transportation vehicles per unit of time are to collect data for the specified route section; and the parameter time interval, which defines the time interval in which data is to be acquired for the route section. Route-related data is continuously transferred to the backend computer from each transportation vehicle of the swarm, wherein a header constitutes an overview of the transportation vehicle-based data stored temporarily in the transportation vehicle.
