Improvements at a congestedintersection require thatthe government acquire the properties on the fourcorners: two gas stations, a church, and a bank.

Fromthe citys viewpoint, which must be included? Fromthe states viewpoint? What viewpoint shouldbe usedto evaluate this project?

The state may eliminate a railroad grade crossingby building an overpass. The new structure, togetherwith the needed land, would cost $1.8 million. Theanalysis period is assumed to be 30 years becauseeither the railroad or the highway above it will berelocated by then. Salvage value of the bridge (actu-ally, the net value of the land on either side of therailroad tracks) 30 years hence is estimated to be$100,000. A 6% interest rate is to be used.About 1000 vehicles per day are delayed by trainsat the grade crossing.Trucks represent40%,and 60%are other vehicles. Time for truck drivers is valuedat $18 per hour and for other drivers at $5 per hour.Average time saving per vehicle will be 2 minutes ifthe overpass is built. No time saving occurs for therailroad.The railroad spends$48,000annually for crossingguards. During the preceding10-year period, the rail-road has paid out $600,000 in settling lawsuits andaccident cases related to the grade crossing. Theproposed project will entirely eliminate both theseexpenses. The state estimates that the new overpasswill save it about $6000 per year in expenses directlydue to the accidents.Theoverpass,ifbuilt, will belongto the state.Should the overpass be built? If the overpass isbuilt, how much should the railroad be asked tocontribute to the state as its share of the $1.8 millionconstruction cost?

The Arkansas Department of Transportation maybuild a new highway between Texarkana and FortSmith, currently a distance of 181 miles. Design 1is a four-lane highway built entirely on the exist- ing route. Design 2 includes a significant reroutingthrough a mountainous region that would reducethe mileage to 166 miles. Design 3 is a fully access-controlled interstate-quality highway with morererouting, which would reduce the total mileage to148 miles.Benefits for this project depend on mileagesaved times the number of vehicles, plus the esti-mated value for the larger number of trips thatwill occur with the shorter and faster routes.

A two-lane highway between two cities, 10 milesapart, is to be converted to a four-lane divided free- way. The average daily traffic (ADT) on the newfreeway is forecast to average 20,000 vehicles perday over the next 20 years. Trucks represent 5% ofthe total traffic. Annual maintenance on the existing highway is $1500 per lane-mile. The existing acci-dent rate is 4.58 per million vehicle-miles (MVM).Three alternate plans are under consideration.Plan A:Improve along the existing developmentby adding two lanes adjacent to the existing lanesat a cost of $450,000 per mile. This will reduceauto travel time by 2 minutes and truck travel timeby 1 minute. The estimated accident rate is 2.50 perMVM. Annual maintenance is $1250 per lane-mile.Plan B:Improve the highway along the existingalignment with grade improvements at a cost of$650,000per mile.

An economic analysis is needed for a new municipalsolid waste landfill. This includes determining thepotential economic benefit from the gas that is gen-erated when solid waste decomposes. The landfill isproposed at 14 acres, with a design capacity of 1 mil-lion cubic yards of capacity.The finalcappingsystemwill require a 3-foot layer over the 14 acres, and thewaste flow rate is 120,000 tons per year. Calculate:(a)The life of the landfill.(b)The average annual methane production (assumeall methane production has ceased by 15 yearsafter landfill closure).(c)The dollar value of annual methane converted toelectricity (neglect collection and energy produc-tion costs).

A developer has proposed a 650-unit residentialdevelopment adjacent to the landfill. The proposalincludes using the gas generated from the landfill toheat the homes (and mitigateodors).To determine theeconomic feasibility of the proposal, the value of thegas for heating purposes must be determined. Deter-mine whether the quantity is sufficient for heatingthe development.Is this economically more attractivethan using fuel oil? Is it operationally feasible?
