Exiting at an unfamiliar metro station, but don't know the direction you need to head next? Use a compass rose to quickly orient yourself.
WMATA should keep the decals sufficiently far away from the station exit that tourists won't stand over them and block escalator exits. In fact, if the decals are placed 10 feet forward from the exit, it could draw unfamiliar visitors forward and out of the way of escalators as they orient themselves.
The decals would work best if they gave primary prominence to the north direction, so that they could be read from a distance and were not dependent on reading the letters.
