Abstract
The American Institute of Graphic Arts in cooperation with the United States Department of Transportation, has created 34 passenger and pedestrian oriented symbols for use in transportation-related facilities. The intent of the project was to produce a consistent and inter-related group of symbols to bridge the language barrier and simplify basic messages at domestic and international travel facilities. The working process attempted to take full advantage of strong and widely recognized existing symbol concepts and introduce new symbol forms only where no satisfactory concepts existed.
