Question
A) The following traffic counts were taken on a rural highway during the morning peak hour
at (9:00-10:00 am) on Saturday of a week.
Time periods (minute)
Number of vehicles
Find:
9:00-9:30 AM
412
9:30-9:45 AM
702
9:45-10:00 AM
254
1. The hourly volume, the peak rate of flow within the hour, and the peak hour
factor.
2. The daily volume for Saturday if the hourly expansion factor (HEF) is 14.
B) At a highway segment, six vehicles travel the same distance of 20 miles during 21, 25, 30,
29, 31, and 25 minutes, respectively. These vehicles have stopped at a check points for about
5 minutes. Find the average running and overall travel speeds.
C) A parking garage located in Misan city center opens its doors to serve 350 vehicles from 8
am to 3 pm. An analysis of data collected at the parking site indicates that these vehicles are
parked for an average of 1.5 hours. If parking efficiency is 0.9, determine the number of
additional spaces needs when the number of space-hours increases by 16%.
