A GUIDE TO ROAD PROJECT APPRAISAL

This note gives guidance on carrying out feasibility studies for road projects in developing countries. It is intended for administrators, economists, transport planners and engineers in road and transport ministries in developing countries who are responsible for preparing or appraising project submissions. This note deals with rural road projects for new construction, upgrading, rehabilitation, stage construction and maintenance. A background description of the engineering and transport issues is provided, and guidance is given as to which aspects of feasibility studies should be undertaken by a transport planner and which requires the advice of a road engineer. The phases involved in executing a road project are outlined, and attention is drawn to the need to collect good data and to identify which data and decisions are the most important. Sections are provided on: a) assessing traffic demand; b) cost estimation; c) geotechnics; d) pavement design; e) geometric design; f) drainage and structures; G) the assessment benefits, such as vehicle operating costs, road maintenance benefits, time savings, reduction in road accidents, and economic development; h) cost benefit analysis; i) rural access roads; j) the analysis of uncertainty; and k) the feasibility study report.
