EFFECT OF TINTED WINDSCREENS ON A DRIVER'S VISION IN DARKNESS

项目名称：	EFFECT OF TINTED WINDSCREENS ON A DRIVER'S VISION IN DARKNESS
摘要：	TESTS WERE UNDERTAKEN TO DETERMINE THE EFFECT OF TINTED WINDSCREENS ON VISIBILITY DISTANCE ON A 3 KM LONG, UNLIT RURAL ROAD WITH A DRY SURFACE. DURING THE JOURNEY OBJECTS, CONSISTING OF BLACK FOAM CYLINDERS 1 M HIGH AND 30 CM IN DIAMETER ERECTED AT THE ROADSIDE, HAD TO BE RECOGNISED BY THE DRIVER. ON THE SAME EVENING SEVERAL JOURNEYS WERE UNDERTAKEN WITH A CONTROL VEHICLE HAVING A CLEAR WINDSCREEN, AND WITH A TEST VEHICLE OF THE SAME TYPE HAVING A GREEN OR BRONZE TINTED WINDSCREEN. THE CRITERION FOR EVALUATING POSSIBLE EFFECTS OF THE TINTED WINDSCREEN ON VISION WAS THE DISTANCE FROM WHICH THE OBJECT WAS PERCEIVED. NEW SCREENS WITH A PROPORTION OF SCATTERED LIGHT OF 0.5 PERCENT AND DAMAGED WINDSCREENS WITH A SCATTERED LIGHT PROPORTION OF ABOUT 1.8 PERCENT WERE EXAMINED. THE SOURCE OF GLARE WAS A PARKED VEHICLE ON THE OPPOSITE CARRIAGEWAY WITH ITS DIPPED HEADLIGHTS SWITCHED ON. THE EVALUATION IS NOT YET COMPLETED. A SEARCH OF THE LITERATURE ON PROBLEMS OF VISION WAS ALSO CONDUCTED.
