The 'DOT pictograms' are a set of fifty
pictograms used to convey information useful to travelers without using words. Such images are useful in airports, train stations, hotels, and other public places for foreign tourists, as well as being easier to identify than strings of text. Among these pictograms are the now-familiar graphics representing
toilets and
telephones. As a result of this near-universal acceptance, some describe them as the "
Helvetica" of pictograms, and the character portrayed within them as 'Helvetica Man' (Lupton).
As works of the United States government, the images are in the
public domain and thus can be used by anyone for any purpose, without licensing issues.
History
In
1974, the
United States Department of Transportation (DOT) recognized the shortcomings of pictograms drawn on an
ad hoc basis across the United States
Interstate Highway System and commissioned the
American Institute of Graphic Arts to produce a comprehensive set of pictograms. In collaboration with
Roger Cook and
Don Shanosky of
Cook and Shanosky Associates, the designers conducted an exhaustive survey of pictograms already in use around the world, which drew from sources as diverse as
Tokyo International Airport and the
1972 Olympic Games in
Munich. The designers rated these pictograms based on criteria such as their legibility, their international recognizability and their resistance to vandalism. After determining which features were the most successful and appropriate, the designers drew a set of pictograms to represent 34 meanings requested by the DOT.
In
1979, 16 symbols were added, bringing the total to 50.
