An observer counts 240 veh/h at a specific highway location. Assume that the vehicle arrival at the location is Poisson distributed, the probability of having one vehicle arriving over a 30 seconds time interval is
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.

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.
Please solve this question. Subject: Transportation engineering . Problem No.5 For the speed data in the table below, find the mean speed and the Standard Devaition of speed. Also find the 85th percentile, the 15th percentile and the median (50th percentile) speed from the cumulative frequency curve. Also find the Pace and Mode.
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
