Method for coordinating road users (2, 3) using a server device, wherein the server device repeatedly creates, from environment data of an environment, a digital central model of the environment and computes respective instruction data (A2, A3) for an action instruction by means of the central model for at least one of the road users (2, 3), wherein the respective action instruction specifies an action to be performed by the respective road user (2, 3) in the environment, and the server device transmits the respective action instruction to the respective road user (2, 3), characterised in that the server device repeatedly provides at least some of the road users (2, 3) with the central model for comparison with the environment and receives, from at least one or some of the road users (2, 3), delta data describing a difference detected by the road user(s) (2, 3) between the environment and the central model and updates the central model on the basis of the delta data and checks, using the updated central model, whether the instruction data (A2, A3) are in need of correction according to a predetermined correction criterion, wherein several road objects (7, 7') are described by the central model and each road object (7, 7') is assigned to one of several predetermined object categories and the following are defined for each object category: a) a frequency of change indicating the maximum rate at which delta data should be generated for each road object (7, 7') in this object category, and/or b) a priority which defines an order with respect to the determination of the difference in order to focus an available computing time, and wherein, when instruction data in need of correction are detected, they are updated by adapting the action instruction to the updated central model and the updated instruction data (A2N) are transmitted to the respective road user (2, 3) for whom the respective action instruction is intended. the server device repeatedly provides at least some of the road users (2, 3) with the central model for comparison with the environment and receives, from at least one or some of the road users (2, 3), delta data describing a difference detected by the road user(s) (2, 3) between the environment and the central model and updates the central model on the basis of the delta data and checks, using the updated central model, whether the instruction data (A2, A3) are in need of correction according to a predetermined correction criterion, wherein several road objects (7, 7') are described by the central model and each road object (7, 7') is assigned to one of several predetermined object categories and the following are defined for each object category: a) a frequency of change indicating the maximum rate at which delta data should be generated for each road object (7, 7') in this object category, and/or b) a priority which defines an order with respect to the determination of the difference in order to focus an available computing time, and a) a frequency of change indicating the maximum rate at which delta data should be generated for each road object (7, 7') in this object category, and/or b) a priority which defines an order with respect to the determination of the difference in order to focus an available computing time, and wherein, when instruction data in need of correction are detected, they are updated by adapting the action instruction to the updated central model and the updated instruction data (A2N) are transmitted to the respective road user (2, 3) for whom the respective action instruction is intended.
