Motorway signs are a good illustration of this principle. Users are usually travelling at great so these signs are provided well before a turn-off-allowing time to get into the correct lane, slow down, and prepare for exiting. Placing signs ahead of the exit means that drivers remain calm, make no sudden movements and are able to get to where they want to go with relative ease. The same principles apply to all signs even at the comparatively gentle pace of walking through the foyer of an exhibition hall or strolling through a park. Repetition of information is not a problem-remember that visitors often enter environments from many different directions and the repetition of information will help nurture trust in the sign system.
