III. 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.
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.
Reynold, Joshua, Dennis and Rogers Consulting Group has a contract to design a major highway project that will provide service from San Fernando to sudipen, La Union. The Consulting Group has been requested to provide an estimated B/C ratio for the project. Relevant data are: initial cost: 20,750,000.00 Pesos Right of way maintenance: 550,000.00 Pesos Resurfacing every 8 years: 10% of first cost Shoulder grading and re-work (every 6 years): 750,000.00 Pesos Average number of road users per year: 2,950,000 Average time savings value per road user: 2.00 Pesos Determine the B/C ratio if i = 8%.
The 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.
Rash, Riley, Reed, and Rogers Consulting has a contract to design a major highway project that will provide service from Memphis to Tunica, Mississippi. R* has been requested to provide an estimated B/C ratio for the project.

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?
6. There are five alternatives for improvement of a road. Determine which alternative should be chosen if the highway department is willing to invest money as long as there is a B/C ratio of at least 1.00.

Dunkin City wants to build a new bypass between two major roads that will cut travel time for commuters. The road will cost $14,000,000 and save 17,500 people $100/yr in gas. The road will need to be resurfaced every year at a cost of $7,500. The road is expected to be used for 20 years. Determine if Dunkin City should build the road using B/C analysis. The cost of money is 8%.
Q2 / Find the number of lane for the design roadway given the following traffic data: ADT = 7651 vehicles/hour in both direction, - 2% grade , K = 12% , D= 55% , Truck 30%, Busses = 10% , Normal growth for design period = 30% , Generated growth = 20%, Development traffic = 250% , Track = 2 PCU , Busses = 3 PCU and Ideal Сараcity = 1300 PCU / hour / lane.
