A road transport investment model for developing countries

  • J. N. Bulman

Abstract

In developing countries investment in rural and inter-urban roads continues to represent a large part of national development programmes. It is therefore important that decisions about such investments are made on the basis of the best possible information. The economic consequences of building roads to particular geometric and structural standards are rarely adequately investigated at project appraisal stage, largely because knowledge of the interaction between the various factors involved is very limited. Usually a set of geometric and structural standards for a road is adopted arbitrarily, and little attention is given to the effect on vehicle operating costs that the choice of alternative design standards would have.
