3. economic analyses
a. Estimates the future transport cost with and without the proposed
improvement (using unit cost, excluding taxes, of owning and operating
typical vehicles on existing roads and estimated future cost of highway
operations existing and on improved types of roads).
b. Estimates of other economic benefits, if any, such as reductions in highway
maintenance cost and increases in the net value of industrial and agricultural
output resulting from the proposed improvements; where factors other than
the road improvements are required to produce additional outputs, an
assessment should be made of the inputs required, their probability, sources
of financing and probable time scale;
c. A comparison of the expected cost of construction, maintenance and
administration (excluding taxes) with the benefits estimated in (a) and (b)
above, indicating first year benefit/cost ratios and internal economic return
over the economic life of the highways and sections thereof; and
d. Evaluation of the sensitivity of the first year benefit/cost ratios and rates of
return to possible variations in the main factors used in the economic
variations.
