- A new freeway is to be designed through a rural area having level terrain. The number of lanes proposed are 2 in each direction. The facility will facilitate 10 percent trucks and buses and 5 percent RVs. If the objective is to provide a LoS C, hwo much traffic volume the facility will facilite in the peak hour. Assume all missing data if necessary.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.

- Upgrading a highway A highway must be constructed to con- nect Village A with Village B. There is a rudimentary roadway that can be upgraded 50 mi south of the line connecting the two villages. The cost of upgrading the existing roadway is $300,000 per mile, whereas the cost of constructing a new highway is $500,000 per mile. Find the combination of upgrading and new construction that minimizes the cost of connecting the two vil- lages. Clearly define the location of the proposed highway. -150 mi- A B 50 mi 50 mi Old roadQ2 / Find the number of lane for the design roadway given the following traffic data: ADT = 7651 vehicles/hour in both direction, - 2% grade , K = 12% , D= 55% , Truck 30%, Busses = 10% , Normal growth for design period = 30% , Generated growth = 20%, Development traffic = 250% , Track = 2 PCU , Busses = 3 PCU and Ideal Сараcity = 1300 PCU / hour / lane.plz, solve this problem, it is not graded question.
