Budget Allocation Planning for Small Road Systems in Peru

In the mountains of Peru, many small towns do not have direct access to roads. Although small roads are important from the perspective of economic development and society, budget allocations usually give priority to regional and national roads in bad condition. In the present work, GIS was applied to prioritize budget allocation at the departmental level. A study case was done for Ayacucho, the Peruvian department with the highest poverty levels. Applying an analytical hierarchy a composite index value for each road section was calculated. This index is composed of multiple factors processed in GIS: (1) distance to an important market; (2) the number of other roads connected to the section; (3) the total population served by the road to (4) access to health and education services offered–mainly in small towns with populations over 1,000 inhabitants; and (5) the benefit/cost calculated using the total population divided by the length of the road multiplied by the rehabilitation or maintenance (M&R) unit cost. All five factors were combined to calculate an index value so that the importance of the roads could be ranked and the budget could be distributed according to that ranking. GIS outputs also help analyze the spatial distribution of the investment in order to avoid over concentration of resources. A buffer area of 5 km of road was obtained, representing one hour of walking time, which is the average distance that people can walk carrying loads. For the market and health and education service access factors, the cost allocation distance tool was applied using a weighted speed. The connectivity indicator was calculated based on the total length of the roads connected to the segment that was analyzed. A higher score was given to a road connected to a longer network. The last factor was the benefit/cost relationship, in this case the total population was considered for the benefit and the cost was calculated based on the road length and a unit cost per kilometer of M&R. A final matrix of results was normalized to sum up the factors to obtain a final index for each road. The roads were ranked based on the final index. A maintenance and rehabilitation plan can be formulated suggesting financing the roads based on the final score.
