Wayfinding and Environmental Signage
D.O.T In 1974 the Department of Transportation developed a set of 50 pictograms, which have continued to be used for the last forty years. They commissioned the American Institute of Graphic Arts to come up with a set of symbols that would overcome some of the errors they could see developing when it came to conveying a message to a growing population consisting of many new cultures. The symbols were designed by Roger Cook and Don Shanosky and the project was overseen by a commitee of lead designers; Thomas Geismar Seymour Chwast, Rudolph de Harak, John Lees, Massimo Vignelli.
