Baguio City wants to build a new bypass between two major roads that will cut travel time for commuters. The road will cost 140,000,000 pesos and save 17500 people 1000 pesos/yr in gas. The road will need to be resurfaced every year at a cost of 75,000. The road is expected to be used for 20 years. Determine if Baguio City should build the road using B/C analysis. The cost of money is 8%.

- A bridge has been constructed between the mainland and an island. The total cost (excluding tolls) to travel across the bridge is expressed as C- 50 + 0.5V, where V is the number of veh/hr and Cis the cost/vehicle in cents. The demand for travel across the bridge is V- 2500 - 10C. (a) Determine the volume of traffic across the bridge. (b) If a toll of 25 cents is added, what is the volume across the bridge? What volume would be expected with a 50 cent increase? 155 (c) A tollbooth is to be added, thus reducing the travel time to cross the bridge. The new cost function is C- 50 + 0.2V. Determine the volume of traffic that would cross the bridge. (d) Determine the toll to yield the highest revenue for demand and supply function in part (a), and the associated demand and revenueа. The Department of Traffic is considering three improvement plans for a heavily traveled road within the city. The road improvement is expected to achieve three goals: improve travel speeds, increase safety, and reduce operating expenses for motorists. The annual dollar value of savings compared with existing conditions for each criterion and additional construction and maintenance costs is shown in Table 1. If the economic life of the road is considered to be. Table 1: Cost and Benefits for Improvement Plans concerning Existing Conditions Alternative Construction Annual Annual Annual Annual Cost ($) Saving Cost Travel Time Operation Maintenance in Benefits($) Saving($) Cost($) Accidents($) 185.000 5000 3000 300 1500 220,000 5000 6500 500 2500 II 310,000 7000 6000 2800 3000III. A state highway department is planning the construction of a 50 mile, four-lane toll road. It estimates that the construction cost (t = 0) will be $200M and annual maintenance costs will be $IM per year. In addition, every 20 years, a major resurfacing will have to be carried out at a cost of $25M. It is estimated that 6 million cars and 400,000 trucks will use the road cach year, and it is decided that the toll charged to a truck will be 4 times that of a car. The interest rate is 7%. I Determine what the toll should be for each car and truck to cover all expenses for a planning period of 40 years. Assume the toll being charged and the estimated traffic flows do not vary year-to-year.
- Please solve this question it is transportation courseThe Department of Traffic is considering three improvement plans for a heavily traveled intersection within the city. The intersection improvement is expected to achieve three goals: improve travel speeds, increase safety, and reduce operating expenses for motorists. The annual dollar value of savings compared with existing conditions for each criterion as well as additional construction and maintenancecosts is shown in the table below. If the economic life of the road is considered to be 60 years and the discount rate is 3.5%, which alternative should be selected? Solve the problem using the four methods for economic analysis.A secondary road in a developing country, 30 km long is to be improved by surface treating the gravel surface without any change in length. The cost of improvement is estimated at $150,000 per km. Present annual transport costs for all traffic on the existing road (vehicle operating cost plus maintenance cost etc.) is estimated at $200,000 per km. After improvement this is expected to reduce to $170,000 per km per annum. Reconstruction takes place in two years with equal expenditure in each year. Assume that in the second year of construction, transport cost on the improved road is equivalent to present costs on half the length and new transport cost on the other half. Would you undertake the project? (MARR = 8% and the project life is 20 years after reconstruction.) Resealing would be required 10 years after reconstruction at a cost of $55,000 per km. Use the Net Present Value method.

The annual dollar value of savings compared with existing conditions for each criterion and additional construction and maintenance costs is shown in Table 1. If the economic life of the road is considered to be 53 years and the discount rate is 4%, which alternative should be selected? Evaluate the two proposals based on economic evaluation criteria using the Net Present Worth (NPW) and benefit-cost ratio (BCR) methods for economic analysis.The demand and supply function for a bridge are the following where C is cost in cents and V is volume in veh / h . Demand V = 1500 - 10C Supply or cost function: C = 120 + 0.5V (a) What is the equilibrium volume of traffic and the associated cost? (b) 20 cents of toll is added to the cost function, what will be the new cost function and the equilibrium volume?7. A toll bridge from Manila to Lapu-Lapu City carries 4000 vehicles per day. The present toll fee is P2.30. When the toll fee is increased by PO.20, traffic volume will decrease by 400 vehicles per day. It is desired to increase the toll fee to a point where revenue will be maximized. Determine the toll change to maximize revenue.
- A toll bridge carries 6000 vch/day The current toll is $3.50/vehicle. Studies have shown hat for each increase in toll of 50 cents, the traffic volume will decrease by 500 veh/day. Jus desired to increase the toll to a point where revenue will be maximized. (a) Write the expression for travel demand on the bridge, related to toll increase and current volume. (b) Determine the toll charge to maximize revenbes. (o Determine traffic in vel/day after the loll increase, (d) Determine the total revente increase with the new tol.2.12 Design Hourly Volume on a 2-lane urban radial road. The road has a 2-way ADT of 6915 vehicles per day. Transportation planners forecast that this road will carry 22.000 vpd ten years from now. What will be the road's DHV ten years from now? Will more lanes need to be added by that future year? Assume that an urban radial road has a capacity of 2000 veh/hr/lane. A rural highway is to be designed as a passenger-car-only facility for an AADT of 35,000 vehicles per day. The lane capacity is (1800 P.c/hr/lane), with 60% of the peak-hour traffic traveling in the peak direction. Determine the number of lanes required.3. 8.5 Two different routes are under consideration for a new interstate highway: Table P8.5 The "long" route Transmountain shortcut Length of Highway 22 miles First Cost $21 million 10 miles 10 miles $45 million Annual Upkeep $140,000 $165.000 Table P8.5 Full Alternative Text For either route, the volume of traffic will be 400,000 cars per year. These cars are assumed to operate at $0.25 per mile. Assume a 40-year life for each road and an interest rate of 10%. Determine which route should be selected.
