A reconstruction project of a 10-mile 4-lane concrete highway is proposed for next year. The initial cost per lane-mile is estimated to be $271000 with zero salvage value at the end of its service life of 30 years. The annual maintenance cost is expected to be $2710 per lane-mile. For a discount rate of 5.3%, compute the equivalent uniform annual cost.

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.
The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
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%.
A 40km gravel surfaced road on a reasonably good alignment, is now carrying an annual average daily traffic of 100 vehicles (10% trucks). The traffic is expected to grow at an annual rate of 5% compounded (for each road type and all vehicles). The minimum attractive rate of return is 10% per annum. It is proposed to pave the road with minor reconstruction and the rest of the project details are shown in Table 1 below. Determine the benefits and costs after the year of paving
13.9. From past records of highway construction and maintenance costs, a state highway de- partment determines the following cost relationships for two-lane bituminous high- ways within the state: c(x) = 0.1.x20 Cm(x) = 3.0-¹ X where the equations hold for (0.5 ≤ x ≤ 10.0) and where x= pavement thickness (inches); c(x)= annualized construction cost (millions of dollars per mile per year); and C(x)= annual maintenance cost (millions of dollars per mile per year). (a) In words, describe the basic tradeoff decision that the highway department must make. (b) Determine the optimal pavement thickness, justifying the type of point found. (c) If pavement thickness can be specified only in whole inches, what is the best pave- ment thickness, considering normal variance in pavement thickness caused by field construction conditions? How sensitive is the optimal cost to small changes in thickness?

Three designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative. Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15%. Show that the result is the same using the present worth, equivalent annual cost, benefit–cost ratio, and rate-of-return methods.

The cost of resurfacing a stretch of highway with asphalt is $7,000,000 and the annual maintenance is $275,000. If concrete resurfacing is used, the cost is $9,750,000 and the annual maintenance is $65,000. Which alternative should be adopted for a 30-year term with a discount rate of 5%?

Identify and briefly discuss at least 3 risks that may be associated with this project. Highway 410/Steeles Road Project- Highway 410 currently has 4 lanes of traffic in each direction, i.e., northbound and southbound, with a 12-ft median between the northbound and southbound lanes- Steeles Road has 3 lanes of traffic in each direction, i.e., eastbound and westbound, with 4-ft median between the eastbound and westbound lanes- For this project the requirement is to: Build two off-ramps from Highway 410 to Steeles Road to, i.e., eastbound and westbound ramps Build two on-ramps from Steeles Road to Highway 410, i.e., northbound and southbound ramps Build a bridge overpass on Highway 410 over Steeles Road
