Question

Transcribed Image Text:The total number of trips from ABC to XYC is 4500. All of the trips are made using car. The government
proposed two alternatives, a train or a bus. The utility is given by the equation:
U = -0.05(TT) - 0.04(WT) - 0.07(W) - 0.2(F) - 0.2(P)
TT = in-vehicle travel time
WT - walking time to terminal
W - waiting time
F- fare
P- parking cost
The travel time for private car is 30 minutes, 35 for bus and 17 for train. Walking time for different terminals for
bus and train is 8 and 14 minutes respectively. The waiting time is 6 and 5 minutes for bus and train
respectively, and the fare for car, bus and train is at $22, $8 and $6 dollars respectively. Parking cost for car is
$6.

Transcribed Image Text:Answer in three (3) decimal places.
Decide the best alternative in terms of trips carried (train or bus).
What is the total number of trips by bus?
What is the total number of trips by train?
Total fare collected if busis chosen.
