Airports can often be crowded places. In the Copenhagen airport, one creative behavioral approach to crowd control was to use tape on the floor. In order to encourage individuals to use doors on the left side of the walkway, tape was placed in a lane towards the left set of doors. This intervention proved to be effective, increasing even more in effectiveness when the tape color was changed from dark green to neon green.
