Technologies and techniques for producing swarm trajectories for a specified lane of a roadway section, wherein a plurality of vehicles driving in the specified lane transmits the respective driving trajectories of the vehicles to a back-end computer, which determines a swarm trajectory for the specified lane from the transmitted trajectories. The vehicles determine specified constraints during driving in the lane, and the determined constraints are transmitted to the back-end computer together with the trajectory in question. The back-end computer determines at least one swarm trajectory for the specified lane as a function of at least one constraint from the transmitted trajectories and the constraints.
