KAn analysis of accidents in a rural state indicates that widening a highway from 30 ft to 40 ft will decrease the annualaccident rate from 1,270 to 660 per million vehicle-miles Calculate the average daily number of vehicles that shoulduse the highway to justify widening on the basis of the following estimates: (1) the average loss per accident is$1,000, (ii) the cost of widening is $107,000 per mile (iii) the useful life of the widened road is 25 years; (iv) annualmaintenance costs are 3% of the capital investment and (v) MARR is 12% per year.Click the icon to view the interest and annuity table for discrete compounding when the MARR is 12% per year.Choose the correct answer belowOA. The average daily number of vehicles is about 36 vehicles per dayOB. The average daily number of vehicles is about 61 vehicles per dayOC. The average daily number of vehicles is about 70 vehicles per dayOD. The average daily number of vehicles is about 43 vehicles per dayOE. The average daily number of vehicles is about 76 vehicles per day.Next

X = average number of vehicles per dayAW (12%) = 0X =-$117,000/mile (A/P,12%, 25) - {(0.03)…

A certain masonry dam requires 200,000 cu m of gravel for its construction. The contractor found two possible sources of gravel with the following data: Average distance gravel pit to dam site Gravel cost /cu.m at pit Purchase price of pit Road construction necessary Overbuden to be removed at P4.20 cu.m Hauling cost per cu.m per km Which of the two sites will give lesser cost? Source A 3.0 km P800,000.00 P350,000.00 P5.00 Source B 1.2 km P10.00 80,000 cu.m P5.00
A state is planning to construct a stretch of highway extending to 60 Kilometer. The state signed a contract based on the BOT option (Build, Operate, and Transfer) with a construction company. The construction company will finish the project in two years (30 kilometers per year), after which it will operate the highway for 25 years. The company generates revenues by collecting a flat fees from the cars using the highway. The following information is available: Cost/Kilometer: 1,000,000 S Number of cars using the highway: 500,000 car for the first year of usage, then increase by 5% a year. - Annual operation cost: 100,000 $ for the first year of usage, then increase by 10,000 $ every year. The company's MARR is 8% per year. Calculate the value of the fee charged/car so that the Net Present worth of the project is 25,000,000 S.
SITUATION3: Under the data collected from the office of Department of Transportation and DPWH over the last 5 years indicate that for each fatality, there are 40 non-fatal injury accidents ($1500 present cost each) and 300 property damage accidents ($2000 present cost each). What is the breakeven value of statistical Me (VSL) needed to justify a highway project if i is 8%? The death rate on a particular three-lane road is 8 per 100 million vehicle-miles. Adding a lane would reduce this to 5 per million, and other accidents would cost $1.5M per mile to build, and annual maintenance would be 3% of the first cost. Assume that the lane would last 40 years. The road carries 10000 vehicle per day. Use reduction factor of 3/8 for all accidents. (Non-CE students no need to answer this item).

Farmers in an arid region of Mexico draw their irrigation water from an underground aquifer. The aquifer has a natural maximum recharge rate of 340,000 gallons per day (i.e., 340,000 gallons per day filter into the underground reservoir from natural resources.) The total product schedule for well operations looks like this: Number of Wells Operating 10 20 30 40 50 60 70 80 06 Total Water Output (Thousand Gal./Day) 100 200 280 340 380 400 400 380 340 The cost of operating a well is 600 pesos per day. The value of water to the farmer is 0.1 pesos per gallon.
An industrial engineering consulting firm usually observes a 90% learning curve rate in the installation of enterprise level software with its clients.
