CALCULATIONS: Average Annual Daily Traffic ( AADT ) Formula; (current traffic volume/day) * ( 1 + i ) n where i = 3%, n = year no. No Build Current traffic volume/day = 3000 For year no.0, 3000 (1 + 0.03) 0 = 3000 per day. = 1095000 per year. For year no.1, 3000 (1 + 0.03) 1 = 3120 per day. = 1138800 per year. For the following years, where n = 2, 3, 4 and 5, the calculations are same as above. Option 1, Option 2 and Option 3 The AADT is same as No Build for each year. Net Present Value cost ( NPV cost ) ( NPV cost ) = ∑ ( M n / ( 1 + I ) n ) + C o Co = initial construction costs, Mn = maintenance costs, n = specific year Example, for the year 2006 in no build NPV cost = $2,500 / ( 1 + 0.03 ) 0 + C o = $2,500.00 + $0.00 = $ 2,500.00

Annual User Cost Annual Use Cost = Travel cost + Operating cost + Accident cost No Build For year no.0, total of AADT is 1095000 per year, with the vehicle mix where cars obtained 80% and trucks 20%. So, total of cars per year for the year 2006 is 0.8*1095000 = 876000 total of trucks per year for the year 2006 is 0.2*1095000 = 219000 User cost; 1. travel time; cars = $13.80/hour , trucks = $16.70/hour from the question table, travel time for no build is 2.4 minutes. So, user cost for cars
