LEGIBLITY TESTS OF REFLECTORIZED AND NON-REFLECTORIZED MOTOR VEHICLE REGISTRATION PLATES

IN ORDER TO FIND OUT THE DIFFERENCE IN LEGIBILITY BETWEEN REFLECTORIZED AND CONVENTIONAL REGISTRATION PLATES FOUR EXPERIMENTS CORRESPONDING TO REALISTIC TRAFFIC SITUATIONS WERE CARRIED OUT. THE PLATES USED WERE BLACK WITH WHITE SYMBOLS, WHITE WITH BLACK SYMBOLS AND YELLOW WITH BLACK SYMBOLS ALL IN 2MM RELIEF. THE WHITE PLATES WERE ALSO TRIED IN A FLAT VERSION. THE RESULTS WERE THAT THE TWO TYPES OF PLATES ARE EQUALLY LEGIBLE UNDER DAYLIGHT. DURING NIGHT UNDER LARGE ANGLES OBSERVER-PLATE-LIGHT SOURCE THE LEGIBILITY OF THE REFLECTORIZED PLATE IS SOMEWHAT POORER THAN THAT OF THE CONVENTIONAL. BUT UNDER ALL CONDITIONS WHEN THERE IS A LIGHT SOURCE IN THE VICINITY OF THE OBSERVER THE REFLECTORIZED PLATES ARE FAR MORE LEGIBLE. SOME OTHER ASPECTS OF THE LICENSE PLATES ARE ALSO DISCUSSED IN CONNECTION WITH A THOROUGH STUDY OF LITERATURE ON THE AREA. /AUTHOR/
