1. A method for selecting at least one connection pattern drivable by road users using a control device, the method comprising the following steps:
receiving trajectory data from at least one area;
determining, based on the received trajectory data, starting points and end points of drivable trajectories;
determining all connection patterns between the starting points and the end points of the drivable trajectories, in the form of connecting lines;
filtering the determined connection patterns by at least one filter;
comparing connection patterns remaining after the filtering with route profiles from the trajectory data;
counting, for each remaining connection pattern, a number of route profiles which correspond to the connection pattern; and
selecting a connection pattern with a highest number of matching route profiles.
