The complete set of 50 passenger/pedestrian symbols developed by the AIGA is available for download, free of charge, in EPS format. You can download individual symbols, or the whole set from the AIGA Web site. This system of 50 symbols was developed for use at the crossroads of modern life: in airports and other transportation hubs, as well as large international events. Produced through a collaboration between the AIGA and the U.S. Department of Transportation, they are an example of how public-minded designers can address a universal communication need.
