Question 2 Given the data below, calculate the benefit/cost (B/C) ratio for a proposed project by comparison with the existing road. The calculations should assume a capital cost of $26.6M for the project, be for a period of 25 years, and assume 5,000 vehicles per day in each direction on a two-lane road. (4 marks) Savings in VOC = length reduction (km) * AADT * $1700 Savings in travel time cost = travel time saved (seconds) * AADT * $19.30 Savings in accident costs = $1.21 million * Number of accidents saved Existing road Proposed road Length (km) 7.3 Operating speed (km/h) 75 85 Accident rate (per 108 veh-km) 25 20 8.2 B/C = Question 2 Given the data below, calculate the benefit/cost (B/C) ratio for a proposed project by comparison with the existing road.
