Abstract:A design and experimental study of traffic control devices, carried out by a multidisciplinary team of psychologists, engineers and graphic designers is described. The work encompasses an appreciation of the background and operation of uniform traffic control devices, an extensive series of laboratory investigations, road tests, and a substantive group of graphic design exercises. The investigation of the basic design elements of a transportation graphics system included the study of legend, pictograph, symbol, color, shape, arrows, and destination signing. Both the laboratory and the road experiment design and data analyses draw heavily on recent advances in the theory of signal detectability, an application of statistical decision theory. Applications of the study techniques to further problems are noted throughout this report. Also included is a graphic design discussion of the urban sign situation.
