a) The traffic volume table below counts was taken on rural a highway during the morning peak hour (8:30-9:30 am) on Monday of a week. Time periods (minute) Number of vehicles a. Determine the hourly volume (HV), the maximum rate of flow within the hour, and 8:30-8:45 AM 8:45-9:00 AM 9:00-9:30 AM 225 463 189 the peak hour factor (PHF). b. Estimate the daily volume for Monday if the hourly expansion factor (HEF) is 19.75. c. Estimate the annual average daily traffic (ADDT) considering the total weekly volume is 11.33% for Monday and the monthly expansion factor (MEF) is 0.632. b) Briefly explain the advantages and disadvantages of the manual method to measure the traffic volume of vehicles along a road.
