Pilot Project to Quantifying Social Benefits of Road Rehabilitation for Project Prioritization

Road improvements have several positive impacts: (i) economic, (ii) poverty reduction, (iii) improved access to services, (iv) reductions in travel time, and, (v) improved connectivity. These impacts play a key role in determining the feasibility of road projects, but no universally accepted methods exist for quantifying the impacts. World Bank commissioned a study in Papua New Guinea for ranking 11 road projects in priority order. Finnish Overseas Consultants developed a methodology for quantifying socioeconomic benefits for each proposed road project. The developed method relies on GIS-Tools. A key concept within the method is the Road’s Area of Influence (RAI). The RAI was defined as a 5 kilometres buffer zone from each road and the total population living within that area represents the affected population of the project. Key information includes the location of the population, schools, health services, police stations, major towns, community meeting grounds, and markets. Impact on women was also considered. The method provides for ranking road improvement projects by assigning each a numerical value based on socio-economic impacts. The method is especially suitable for micro scale study of socio-economic impacts of road rehabilitation projects. Key challenges related to the method include the availability and reliability of data for the analysis.
