Chapter 04, Problem 041 Recent development near Eugene, Oregon, has identified a need for improved access to Interstate 5 at one location. Civil engineers and public planners are considering three alternative access plans. Benefits are estimated for the public in general; disbenefits primarily affect some local proprietors who will see traffic pattern changes as undesirable. Costs are monetary for construction and upkeep, and savings are a reduction in cost of those operations today that will not be necessary in the future. All figures are relative to the present situation, retention of which is still an alternative, and are annualized over the 20-year planning horizon Alternative Benefits Disbenefits Costs Savings $280,000 $370,000 $490,000 $37,000 $69,000 $102,000 $180,000 $269,000 $347,000 $15,000 $31,000 $42,000 What is the B/C ratio for each of these alternatives? Alternative A: Alternative B: Alternative C: Carry all interim calculations to 5 decimal places and then round your final answer to 2 decimal places. The tolerance is 0.01 Using incremental B/C ratio analysis, which alternative should be selected? Please show the ratios used to make your decision: Comparison 1: Comparison 2: Comparison 3: Carry all interim calculations to 5 decimal places and then round your final answer to 2 decimal places. The tolerance is 0.01 Alternative A or C, as they are equally desirable Alternative C Alternative A Alternative B or C, as they are equally desirable Alternatives A, B, and C are equally desirable Alternative DN Alternative B Alternative A or B, as they are equally desirable Ratio: Ratio: Ratio: Determine the value of B - C for each alternative Alternative A: $ Alternative B: $ Alternative C: Carry all interim calculations to 5 decimal places and then round your final answer to the nearest dollar. The tolerance is 10
