Assume that the speed-density function of a section of a highway follows the Greenshields model. The free-flow speed is 75 mph and the jam density is 176 veh/mi/In. Derive V as a function of S. In 15 minutes, you have counted that V = 150 veh/15-minute/In. Estimate the two possible speeds S (in mph) during this 15-minute period.

Measurements from a single-lane roadway reveal that the average spacing and headway between passing vehicles are 200 ft and 2.4 seconds, respectively. What is the flow [veh/hr], density [veh/mi] and average speed [mi/hr] of traffic on this roadway?
F] Vehicles travel at constant speeds on a one-lane one-way street between sections X and Y. An observer located at point X observes the four vehicles passing point X during a period of 10 seconds. The speeds of the vehicles are measured as 45, 45, 40, and 30mph, respectively. Calculate the average flow, density, time mean speed, and space mean speed.
Considering linear relationship between density and speed; you are required to estimate the corresponding flow and speed values to densities of 10, 20, 30, 40, 50, 60 and 70 vehicle/km if the free flow speed is 90 km/hr and at critical situation, it is founded that there are 110 vehicles on a section of road with length 2.0 km. using the estimated values, draw a sketch showing the speed flow - density relationships?

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
