1. A method of visualizing output data of a traffic planning method for controlling a plurality of vehicles, wherein each vehicle occupies one node in a shared set of planning nodes and is movable to other nodes along predefined edges between pairs of the nodes, wherein the output data indicates respective planned node occupancies of the vehicles for a sequence of time steps, the method comprising:
rendering a graphical representation of the planning nodes using a graphical output interface; and
in the graphical representation, indicating each vehicle's planned movements between the nodes by rendering linear graphical elements,
wherein an appearance parameter of the linear graphical elements has a time variation with respect to the time step, which time variation is common to all vehicles, such that all locations in the graphical representation with equal values of the appearance parameter refer to a corresponding time step.
