DIAGRAMMATIC HIGHWAY SIGNS: THE LABORATORY REVISITED

The experiment summarized in this report was designed to establish a low-cost reliable laboratory technique for the evaluation of highway guide signs and to resolve differences in previous laboratory studies with regard to diagrammatic guide signs. It was found that the differences in two previous studies on diagrammatic signs could be resolved if one simply applied the same criteria for the scoring of the data to each of the studies. Therefore, the methodology established in the current investigation, which controlled for methodological differences in earlier studies, was concluded to be a reliable means for assessing the impact of guide sign changes. The validity of the methodology is yet to be established. Response times were consistently longer for diagrammatic signs than for conventional signs. This difference was probably due to an increase in information on diagrammatic signs. Subjects reported being more confident of and having a preference for conventional signs. The corrections of lane choices was slightly higher for conventional signs than for diagrammatic signs.
