Airplanes anive at an airport area at an average rate of six per hour according to the Poisson distribution. The airport control tower processes airplanes in their order of arrival. Assuming that the service time is negative exponential'and that the service rate is ten landings per hour, calculate (1) the average number of airplanes in the system (i.e., being served and stacked), (2) the average number Of airplanes aW~ting clearance to land, (3) the average time spent in the system, and (4) the average time an airplane is in the queue.

A calibration study resulted in the following utility equation for different modes in a particular city;??=??−(0.25)(?1)−(0.032)(?2)−(0.015)(?3)−(0.002)(?4)where ??= mode specific constant?1= access plus egrees time in minutes?2= waiting time in minutes?3= line-haul time in minutes?4= out-of-pocket cost in centsFor a particular origin-destination pair, the forecasted number of trips is 5,000. For this particular trip, there are two modes available, bus and auto.a) If the characteristics of these two modes are as follows, how many trips will be taken by bus? And by car? Assume that the mode specific constant is equal to -0.12 for the automobile and -0.22 for bus.b) Assume that a new mode, rapid transit, is to be introduced into the market between these two zones. The characteristics of this new service are as follows:?1=10 ?2=5 ?3=30 ?4=75 Assume from experience in other cities that the mode specific constant for rapid transit is -0.41. What willbe the modal shares of the 5,000 trips…
A parking garage has a single processing booth where cars pay for parking. The garage opens at 6:00 A.M. and vehicles start arriving at 6:00 A.M. at a deterministic rate of 3(t) = 6.1 - 0.22t where 3(t) is in vehicles per minute and t is in minutes after 6:00 A.M. What is the minimum constant departure rate (from 6:00 A.M. on) needed to ensure that the queue length does not exceed 10 vehicles? Answer in veh/min. 4 (with margin: 0.3)

At a specified point on a highway, vehicles are known to arrive according to a Poissonprocess. Vehicles are counted in 30-second intervals, and vehicle counts are taken in 120 ofthese time intervals. It is noted that no cars arrive in 18 of these 120 intervals. a) Approximate the number of these 120 intervals in which exactly three cars arrive. b) Estimate the Percentage of time headways that will be 10 seconds or greater andthose that will be less than 6 seconds.

An airport runway accommodates 18 arrival flights in an hour and departure flights occur every 2.1429 minutes during normal weather season. During holidays, arrival flights are increase to 24 but on bad weather conditions, departure flights is changed to 2.727 minutes due to a decline in flight departures. Determine the queueing characteristics of the airport during these conditions.
