Abstract : This paper describes a design and experimental study of the placement of guidance arrows on highway guide signs. In this study, conducted under laboratory conditions, ten subjects were shown a series of slides depicting three destinations, three directions and three sign designs under controlled instruction and exposure duration; they were required to respond to a previously determined cue as quickly and as accurately as possible. The measured variables were response time and correctness of response. Classical statistical tests were made to determine the optimum guidance sign arrangement of arrows and destination names.
