EVALUATION OF SYMBOLS FOR TRAFFIC SIGNS
Traffic signs containing messages in symbol form have several advantages over those containing messages in legend form. Their legibility distance is greater, their meaning can be interpreted more quickly and they overcome the language problems faced by migrants and poor readers. However, these advantages only accrue if the symbols are easily comprehended. Before introducing symbols evaluation is therefore required. Candidate symbols for each of 23 commonly used legend and/or hybrid signs contained in the Australian traffic signs manual were evaluated for ease of comprehension. Specific recommendations regarding conversion to symbol form and the nature of the preferred symbol are made for each sign. The evaluation method used was based on that recently promulgated by the Standards Association of Australia. A major weakness of this method is the degree of reliance it places on the results of a measure of ease of learning, a measure which seems of insufficient sensitivity and of questionable validity. Modifications to the method are recommended. (Author/TRRL)
