Plz answer two question clearly

1. Two platoons of cars are timed over a distance of 0.7 km. Their flows are recorded. The first group is timed at 60 seconds, with the flow at 2350 vehicles per hour. The second group take 65 seconds, with a flow of 2800 vehicles per hour. Determine the maximum flow of the traffic stream. 2.Adivided rural multi-lane highway is required to cope with an AADT of 60000 vehicles per day, on level terrain. A 60 mph design speed is chosen with lanes a standard 3.05 m wide and there are obstructions on one side, with 1.22 m of any travelled edge. The traffic is assumed to be composed entirely of different cars and the driver population is ideal. The peak hour factor is 0.8 and the directional factor, D, is estimated at 0.5. The highway is required to maintain level of service D. It is to be designed to cope with the thirtieth highest hourly volume during the year. Calculate the required physical extent of the highway, i.e. the number of lanes required in each direction. The percentages for the various heavy vehicle types are: Pr – 10% PB - 4% PR- 2%
