help me pls. Ill upvote thankyou :)
Thank youuu please provide a detailed solution.
Consider the following plot of cumulative arriving and departing vehicles at a freeway bottleneck location:
Vehicles
20,000
15,000
10,000
5,000
0
0
30 60 90 120 150 180 210 240 270 300 330 360
Time (mins)
Arrivals (vehs) Departures (vehs)
From this plot, determine the following:
A. What is the capacity of the bottleneck location? 9000
whole number, i.e. X000.)
B. What is the maximum size of the queue that develops? 3250
whole number, i.e. X000.)
C. What is the longest wait time that any vehicle experiences during the breakdown?
to the nearest whole number, i.e. XX.)
(Hint: Provide the answer as a numerical number only in units of vehicles per hour and rounded to the nearest thousand
(Hint: Provide the answer as a numerical number only in units of vehicles and rounded to the nearest thousand
(Hint: Provide the answer as a numerical number only in units of minutes and rounded
