Abstract:This research was undertaken to evaluate the effectiveness of a diagrammatic sign as compared to a conventional sign at a particular location. The measure selected for determining sign effectiveness was erratic traffic maneuvers. It was assumed that any significant differences in the proportion of erratic maneuvers "before" and "after" the diagrammatic sign was controlled would be directly attributable to the change in signal.
On the basis of the data collected it was considered that a diagrammatic sign was not warranted at the subject location. The project was terminated after the "before" portion of the study.
