Method for preevaluation and selection of road projects in Gabon

A method for preevaluation and selection of road projects in the open country adapted to the particular conditions of Gabon is presented. This method is both the most complete possible given the state of current knowledge, and sufficiently simple to be carried out easily. Although based on the classic micro-economic method of choosing road investments, it adds potentiality criteria, related to agricultural and forestry production, of a more economic nature, and usage criteria of a more social nature, to the classic econometric criteria. The package permits the selection of projects with the greatest utility to the national collectivity. This method, which is relatively simple and practical, is capable of handling the types of project interdependencies often encountered among road investment projects, especially in developing countries.
