A divided multilane highway in a recreational area (fp = 0.90) has four lanes (two lanes in each direction) and is on rolling terrain. The highway has 10-ft lanes with a 6-ft right-side shoulder and a 3-fl left-side shoulder. The posted speed is 50 mi/h. Formerly, there were 4 access points per mile, but recent development has increased the number or access points to 12 per mile. Before the development, the peak-hour factor was 0.95 and the directional hourly volume was 2300 vehicles with 10% large trucks and buses and 3% recreational vehicles. After the development, the peak-hour directional flow is 2700 vehicles with the same vehicle percentages and peak-hour factor. What is the level of service before and after the development?

Consider the two-dimensional steady flow where the velocity field is given by V=Vo/L(-xi+yj) . Determine the streamlines for this flow. Plot streamlines for x> or =0
Given that uniform flow is subcrital and there is a weir in a rectangular channel, how do you determine what the weir height should be to force the flow to be critical. Draw this transition on a specific energy curve.
