A method for collecting transportation vehicle-based data, in particular environmental data, and transferring the data to a backend computer, wherein the respective data sets relate to predefined route sections (S1,..., Sn) travelled by a swarm of data-collecting vehicles, characterized in that parameterized orders (A1,..., An) for acquisition of transportation vehicle-based data are stored in the backend computer, wherein each order comprises at least the following parameters: - route section (S1,..., Sn) which defines a route section for which transportation vehicle-related data is to be collected, - swarm size (F1,..., Fn) which defines how many transportation vehicles per unit of time are to collect data for the specified route section, and - time interval (t1,..., tn) which defines a 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 as a header that includes an overview of the transportation vehicle-based data stored temporarily in the transportation vehicle, a transferred header is compared with requirements of the orders (A1,..., An) defined by the parameters of the route section (S1,..., Sn), swarm size (F1,..., Fn) and time interval (t1,..., tn), in response to a positive comparison, the transferred header is classified as capable of being retrieved and the data set assigned to the header is retrieved from the transportation vehicle and transmitted for further processing to the backend computer. parameterized orders (A1,..., An) for acquisition of transportation vehicle-based data are stored in the backend computer, wherein each order comprises at least the following parameters: - route section (S1,..., Sn) which defines a route section for which transportation vehicle-related data is to be collected, - swarm size (F1,..., Fn) which defines how many transportation vehicles per unit of time are to collect data for the specified route section, and - time interval (t1,..., tn) which defines a time interval in which data is to be acquired for the route section, - route section (S1,..., Sn) which defines a route section for which transportation vehicle-related data is to be collected, - swarm size (F1,..., Fn) which defines how many transportation vehicles per unit of time are to collect data for the specified route section, and - time interval (t1,..., tn) which defines a 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 as a header that includes an overview of the transportation vehicle-based data stored temporarily in the transportation vehicle, a transferred header is compared with requirements of the orders (A1,..., An) defined by the parameters of the route section (S1,..., Sn), swarm size (F1,..., Fn) and time interval (t1,..., tn), in response to a positive comparison, the transferred header is classified as capable of being retrieved and the data set assigned to the header is retrieved from the transportation vehicle and transmitted for further processing to the backend computer.
