1- You are assigned to evaluate the level of service for a section of a six-lane rural highway that stretches along a level terrain with shoulder width of eight ft and lane width of twelve ft. The average annual daily traffic is fifty-five thousand vehicles per day with ten percent trucks, five percent buses, and three percent recreational vehicles. The peak hour factor is 0.80 and the directional split is fifty-fifty. The distance between consequent interchanges is two miles. Calculate the level of service for this highway section and show your calculation steps.
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%.

5- Traffic volume study was conducted in a section of road in month of April the following information's was obtained ( HEF=18, POV =650 veh/h, total weekly volume =72450 veh/week, total yearly volume = 23770 veh lyear, MEF =1/2 DEF). So, the ADT of this month? (Assume total daily volume = average daily volume) * O 7923 veh 850 veh 660 veh O 1240 veh
