Abstract

ESCOBAR GARCIA, Diego Alexánder; CADENA GAITAN, Carlos  and  SALAS MONTOYA, Andrés. GEOSPATIAL COVERAGE OF PRIMARY ACTIVITY NODES: CONTRIBUTION TO URBAN SUSTAINABILITY ANALYSIS BY USE OF A REGIONAL ACCESSIBILITY STUDY. Rev.EIA.Esc.Ing.Antioq [online]. 2015, n.23, pp.13-27. ISSN 1794-1237.

We apply geostatistical techniques in order to assess the relationship between the operating characteristics offered by the urban transport network in the city of Manizales (Colombia) and the geospatial location of the Primary Activity Nodes (PAN). The PAN are those that supply vital community needs such as: Health, Education, Recreation and Safety. This research is built on a set of more than 18 million GPS data points, compiled throughout a period of one year. Average travel times to reach the PAN and geospatial coverages in regards to population and area, are calculated. Graphical results are presented, explaining the required travel times to reach a certain NAP, and performing quantitative comparisons across the geoespacial coverage thereof. We identify the areas of the city indicating deficient coverage of the NAP, in relationship to the urban transport systems. Finally, we describe the benefits of the methodology and offer it as an approach to optimize urban sustainable planning processes, and areas of influence.

Keywords : Accessibility; Geostatistic; Activity Nodes; Sustainable Mobility.
