velocity is measured at 65 km/h and the speed flow of 1,600 vehicles/hour/lane. What is the

Assume you are observing traffic in a single lane of a highway at a specific location. You measure the average headway and average spacing of passing vehicles as 3.2 seconds and 20 m, respectively. Calculate the flow, average speed, and density of the traffic stream in this lane.

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

Two cars P and Q are moving in a racing track continuously for two hour. Assume that no other vehicles are using the track during this time. The expressions relating the distance travelled d (in km) and time t (in hour) for both the vehicles are given as P: d = 60t Q: d = 60t² Within the first one hour, the maximum space headway would be
