After implementing service improvements to the mass transit, the mode split changed to 81.4% private automobile use and 18.6% mass transit use. Determine a value for the waiting time for the mass transit mode that reflects this shift in mode split.
Commuters choose auto or bus for their trips. The utility function for each travel mode was calibrated as follows: where V=C-0.10* X₁ -0.13* X₂-0.12 X3-0.0045 X4 * V = observable utilities; C = constant; X₁ = waiting time (min); X₂ = travel time (min); X3 = parking time (min); X₁ = out-of-pocket cost (cents).

Assume that the benefits of the gymnasium are the same for both construction methods. Alternative A: Wooden bleachers on earth fill The first cost of $110.000 for the earth fill and $100.000 for the wooden bleachers. The annual painting costs are $5.000. The wooden bleachers must be replaced every 30 years at a cost of $100,000. The earth fill will last the entire 120 years Alternative B: Concrete Bleachers The first cost is $350,000. The expected life of the concrete bleachers is 120 years and the annual upkeep costs are $2.500 The university Uses a MARR of 7%. Which of the two alternatives is better? Opening in Google Drive.
A household has 17 members and an annual income of P20,000. They currently live in a neighborhood with 550 retail employees, but are moving to a new home in a neighborhood with 150 retail employees. Calculate the additional vehicle-based peak- hour shopping trips the household makes before and after the move. Use: Vehicle-based Shopping Trips = 0.12 + 0.09HS + 0.011AHI - 0.15EH HS - household size AHI - annual household income in thousand pesos EH - employment in household's neighborhood in hundreds Note: use two decimal places
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 and 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 20 minutes, 12 for bus and 10 for train. Walking time for different terminals for bus and train is 10 and 15 minutes respectively. The waiting time is 8 and 6 minutes for bus and train respectively, and the fare for car, bus and train is at $20, $8.5 and $7 dollars respectively. Parking cost for car is $3. What is the total number of trips by train?
1-9. Automobile repair shops typically recom- mend that their customers change their oil and oil filter every 4,000 miles. Your automobile user's manual suggests changing your oil every 8,000–10,000 miles. If drive you your car 16,000 miles each year and an oil and filter change costs $35, how much money would you save each year if you had this service performed every 8,000 miles? (1.3)
