SPEEDS AT JUNCTIONS, AT DANGER SIGNS, ON BENDS AND ON SECTIONS SUBJECT TO SPEED LIMITS

项目名称：	SPEEDS AT JUNCTIONS, AT DANGER SIGNS, ON BENDS AND ON SECTIONS SUBJECT TO SPEED LIMITS
摘要：	A LARGE PROPORTION OF ACCIDENTS ON ROADS OUTSIDE URBAN AREAS ARE DUE TO THE FACT THAT SPEEDS ARE NOT SUITABLE TO THE CONDITION OF THE ROAD. WAYS OF POSITIVELY INFLUENCING A DRIVER'S CHOICE OF SPEED AND THUS REDUCING DANGEROUS SITUATIONS, PARTICULARLY ON BENDS, HAVE HITHERTO NOT BEEN STUDIED SUFFICIENTLY. AS SELECTION OF CORRECT SPEED IS MAINLY A PROBLEM OF OPTICAL INFORMATION BEING GIVEN IN ADVANCE, FAULTS IN ALIGNMENT AND RESULTANT ACCIDENT BLACK SPOTS HAVE TO BE MADE LESS ACUTE BY SUITABLE OPTICAL SIGNALS SUCH AS OFFICIAL TRAFFIC SIGNS, WARNING SIGNS OR MARKINGS ON THE CARRIAGEWAY. THE STUDY IS CONCERNED WITH WAYS IN WHICH THE EXTENT OF A NECESSARY SPEED REDUCTION BEFORE BENDS CAN BE INDICATED IN SUCH A WAY THAT DRIVERS' SPEEDS ARE CONSCIOUSLY OR UNCONSCIOUSLY INFLUENCED AND ERRORS ARE LARGELY AVOIDED. THE EXTENT TO WHICH LOCALLY AND TRAFFIC-CONDITIONED SPEED RESTRICTIONS ON ROADS OUTSIDE TOWNS ARE OBSERVED AND THE EFFECT OF POLICE SURVEILLANCE ON SPEEDS ARE ALSO TO BE EXAMINED.
