ESTIMATING TRAFFIC VOLUMES BY SYSTEMATIC SAMPLING

METHODS OF STATISTICAL ANALYSIS USED IN OBTAINING ANNUAL AVERAGE OF DAILY TRAFFIC (ADT), AND THE DURATION AND PEAK VALUES OF CRITICAL HOURS ARE DESCRIBED. THE PATTERN OF TRAFFIC FLUCTUATIONS FORMS THE BASIS FOR THIS METHOD, THE FLUCTUATIONS BEING DETERMINED BY MEANS OF THE PROBABILITY THEORY USING THE LATEST METHODS OF MATHEMATICAL STATISTICS. THE APPLICATION OF THE TRAFFIC COUNTING METHOD IS DESCRIBED FOR TRAFFIC FLOW SURVEYS. SAMPLING METHODS USED FOR DETERMINATION OF ADT ARE DISCUSSED. THE FOLLOWING TYPICAL CHARACTERISTICS OF TRAFFIC FLUCTUATIONS ARE USED: (1) FLUCTUATIONS DURING THE 24 HOURS OF A DAY, (2) FLUCTUATIONS DURING THE SEVEN DAYS OF A WEEK, AND (3) FLUCTUATIONS DURING THE 52 WEEKS OF THE YEAR. A METHOD IS ILLUSTRATED TO DETERMINE RELIABLY THE RELATION BETWEEN PEAK-HOUR FLOWS AND THE ADT ON THE VARIOUS ROAD TYPES OF RURAL HIGHWAYS BY MEANS OF THE FACTORS DISCUSSED.
