Example: It is proposed to construct a self-financing road tunnel. The criterion is that the toll paid by the vehicles over the life of the project must be sufficient to cover both the initial capital and the other costs which will be incurred over the project's life. Determine a suitable charge on each vehicle passing through the tunnel using the following estimated figures based on 1996 prices. 1. Capital cost Construction cost Land cost Professional fees 2. Annual OMR cost 3. Annual administration cost 4. Replacement cost of autopay ticket machine 5. Estimated annual traffic flow 6. Life of project 7. Required rate of return (real) 8. Estimated inflation rate in the next 20 years $100,000,000 $2,500,000 $5,000,000 $1,000,000 every 5 years 10,000 vehicles per day in the first five years; the growth rate of traffic flow is 30% every 5 years 20 years 12% 10% p.a.
