SHOW A FULL SOLUTIONAfter mall opening, the traffic volume (demand) in a certain road section (6-lane divided highway) at the peak hour is forecasted to be 5200vph. An accident blocks 1 lane of the highway. It took 15 minutes till the accident is cleared and capacity is fully restored. Use the following speeddensity relationship: u=112.81-1.75k (u is speed in kph and k is density in vpk/lane) to answer the following questions:a.) Determine the free-flowing speedb.) Compute for the shockwave between the free-flow state and the state where there is capacity reduction due to accident.c.) Compute for the shockwave between state when there is capacity reduction due to accident and the state where vehicles flow with full section capacity
