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
9. Calculate the estimated free flow speed of a Class II two-lane highway if the field measured mean speed is 56.5 mph and the flow rate during the field data collection was 650 vph and all vehicles are passenger vehicles.
Q2 /a/ There was a need to know the volumes traffic for a rural project where 24 hrs. flows were counted on Thursday, Friday and Saturday in December as follow, Thursday = 8000, Friday = 8000 and Saturday = 10000. Q2 /b/ Design data is required for improvement of two – lane of two way highway with central reserve. The current traffic in 2016 expressed by AADT is 3000 vehicles. The improved road with a design life of 20 years will opened to traffic in 2021, the estimated annual growth rate of traffic is 8%, K-factor is 12% of AADT and D (Directional distribution) is 55% of total traffic. Find DDHV.
You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS C using the 40th highest annual hourly volume (K = 0.116). A 6 B) 4 c) 10 D) 8
Q2/ The average number of vehicles in each month was calculated as shown in table below. Calculate: 1- The annual average daily traffic. 2- The expansion factor for each month.

8. A two-lane highway is expected to serve ADT of 5000 veh, find DHV and DDHV in veh and pcu if the following information is given: K=0.1, D=0.6 Traffic composition includes 80 passenger cars and 20% trucks.
with central reserve the current traffic in 2019 expressed by AADT is 3000 vehicle in both direction. the improved road with design life traffic 20 years will be opened to traffic in 2024.

You are designing a freeway as a passenger-car-only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a peak-hour factor of 0.88, and a directional distribution of 0.65. day. It is estimated that the freeway will have a free flow speed of 70mi/h. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume. Use k =0.11.
Given the following data: design life n -= 15 years, lane distribution factor D = 0.75, annual rate of growth of commercial vehicles r = 6%, vehicle damage factor F = 4 and initial traffic in the year of completion of construction = 3000 Commercial Vehicles Per Day (CVPD). As per IRC : 37-2012, the design traffic in %3D terms of cummulative number of standard axles (in million standard axles, up to two decimal places) is
If current ADTS of a highway is 24,000 and rate of annual growth in traffic is 3% for 18 years design life and 2years of construction,Traffic projection factor will be equal to 3 5 O
The average daily traffic on a stretch of road is 300 commercial vehicles per lane per day. Design traffic repetitions for 10 years when vehicle damage factor is 2.5 and traffic growth rate is 7% is
