- Consideration is being given to increasing the toll on a bridge now carrying 4500 veh/day. The current toll is $1.35/veh. It has been found from past experience that the daily traffic volume will decrease by 400 veh/day for each 25¢ increase in toll. Therefore, if x iš the increase in toll in cents/veh, the volume equation for veh/day is V= 4500 - 400 (x/25), and the new toll/veh would be T = 135 + x. In order to maximize revenues, what would the new toll charge be per vehicle, and what would the traffic in veh/day be after the toll increase?arrow_forwardSuppose you are going on a long trip to your grandmother’s home in Seattle, 3,000 miles away. You have decided to drive your old Ford out there, which gets approximately 18 miles to the gallon when cruising at 70 mph. Because Grandma is an excellent cook and you can stay and eat at her place as long as you want (for free), you want to get to Seattle as economically as possible. However, you are worried about your fuel consumption rate at high speeds. You also have to balance cost of food, snacks, and sleep to balance against the cost of fuel. What is the optimum average speed you should use so as to minimize your total trip cost, CT?arrow_forwardA secondary road in a developing country, 30 miles long, is to be improved by surface treating the gravel surface without any change in length. The cost of the improvement is estimated at $150,000 per mile. A present annual transport cost for all traffic on the existing road (vehicle operating cost, maintenance cost, etc.) is estimated at $205,000 per mile. After improvement, this is expected to reduce to $170,000 per mile per annum. Reconstruction takes place in two years with equal expenditures in each year. Assume that in the second year of construction, transport cost on the improved road is equivalent to present costs in half the length and new transport cost on the other half. Would you undertake the project? (The minimum attractive rate of return (MARR) is 8.5% and the project life is 20 years after reconstruction.) Resealing would be required 10 years after reconstruction at a cost of $55,000 per mile. Use the net present worth methodarrow_forward

(a) Calculate the net user benefits per year (in dollars) if the cost decreases from $1.50 to $0.75/trip (assume a linear demand function). $ 29 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results roundoff error.

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?

The vehicles that carry these people include; (1) personal vehicles (average occupancy of 1.2 people per car) 2-2 kip single axles, and (2) buses with 2-22 kip single axles (assume they are filled with an average of 40 passengers). There are also trucks on the roadway and all trucks have 1-40 kip triple axle, 1-32 kip tandem axle, and 1-8 kip single axle.
