Abstract: In Latin America, there is a wide gap between kilometers of paved ways and those with no type of protection. This situation is worse in rural areas, limiting development opportunities and inhabitants’ quality of life. In Chile, there are state programs that seek to reduce the territorial gap through basic low-cost paving solutions; however, the prioritization criteria for rural roads are unclear. Multiple actors affect the rural territories, and the non-existence of reference patterns increases subjectivity in infrastructure decision making. This study attempts to determine criteria that influence the selection of rural roads in southern Chile to promote sustainable territorial development considering multiple actors and the uncertainty of the selection process. For this, a documentary review, field visits, and 12 semi-structured interviews were conducted. The criteria are validated through a multidisciplinary panel of experts and the application of neutrosophic numbers to address the uncertainty derived from the expert consultations. The results of this study contribute 14 sustainable criteria in order to support the planning of basic rural roads in southern Chile.
