Abstract: Disclosed is a method for guiding passengers of public transport, in particular of trams or trains respectively, at stations or in station areas and/or inside the transportation unit. The passengers embark and disembark in the embark-/disembark area via at least two doors, and the embark-/disembark area extends to the length of the vehicle.
