This research applies geostatistical techniques to explain the level of coverage presented by the transport infrastructure of the city of Quibdó in relation to the Primary Activity Nodes (PAN), which are those that allow meeting the minimum daily needs of a population: Health, Education, University studies and Security. The methodology is based on an analysis of accessibility to these nodes through the calculation of the Integral Mean Accessibility offered by the infrastructure network. The objective is to analyze the location of the PANs based on their relationship with the operational characteristics of the transport infrastructure network. It was obtained that the PANs that have the best spatial coverage characteristics are Educational, followed by the PAN Health and PAN Universities, which report similar levels of coverage of the variables population, number of households and area. While those nodes that report a poorer coverage are those of Security.
