CERTAIN STRUCTURAL COMPONENTS OF LETTERS FOR IMPROVING THE EFFICIENCY OF THE STOP SIGN
THE TYPES, STROKE, AND SPACING OF LETTERS AND BACKGROUND COMBINATIONS FOR STOP SIGNS ARE INVESTIGATED IN AN EFFORT TO GIVE A GREATER LEGIBILITY DISTANCE AND EFFICIENCY THAN HAS SO FAR BEEN ACHIEVED. STUDY WAS GIVEN TO THE INDIVIDUAL CHARACTERISTICS OF EACH LETTER. A STROKE BETWEEN .18 AND .25 THE WIDTH OF THE LETTER WAS FOUND TO GIVE BEST RESULTS. IT WAS ALSO INDICATED THAT LETTERS ARE CROWDED MUCH TOO CLOSELY TOGETHER FOR MAXIMUM EFFICIENCY. BLACK LETTERS ON A WHITE BACKGROUND ARE SUPERIOR TO WHITE LETTERS ON A BLACK BACKGROUND. THE FEWER THE ITEMS ON THE BACKGROUND, THE HIGHER THE EFFICIENCY OF THE SIGN. THE RELATIVE MERITS OF DIFFERENT COLORS OF REFLECTORIZED BACKGROUNDS AND THE VISUAL RECOGNITION OF AN OCTAGONAL SIGN ARE DISCUSSED. /AUTHOR/
