Question 2 (30 points): Demonstrate that for this highway construction project, the same B/C ratio is obtained using the present and annual worth formulations. Initial costs of construction $1,500,000 Annual costs for maintenance 65,000 Annual benefits to travelers 225,000 Residual value after useful life 300,000 Useful life of investment 30 years Interest rate 8% Question 3 (30 points) The New Jersey Department of Transportation is improving several ramps on the Interstate highway 1-80. Calculate the annual benefits (travel time and safety) of this improvement if the following parameters are provided Total AADT entering the interstate: highway 20,000 vpd; Vehicle mix: 85% cars (assume occupancy of 1.2 persons/veh), 15% trucks (assume single occupancy): Average control delay without the improvement: 60 seconds; Average control delay with the improvement: 40 seconds; Average annual number of fatal accidents without the improvement: 0.3; Average annual number of injury accidents without the improvement: 7.1; Average annual number of PDO accidents without the improvement: 10.4; The corresponding AMF is 0.8 for all accidents accident types.
