Abstract

MONTOYA, Jorge A.; ESCOBAR, Diego A.  and  MONCADA, Carlos A.. Urban accessibility analysis from road interventions through geographic information systems. Case Study, the road network of the Quibdó municipality, in Colombia. Inf. tecnol. [online]. 2020, vol.31, n.2, pp.19-30. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642020000200019.

This research seeks to establish the level of impact generated by the implementation and intervention of the road network of the municipality of Quibdó (Department of Choco in Colombia), within the framework of the project Integral Mobility Plan for a short term (2025). This plan was carried out by the National University of Colombia, Manizales branch, and the municipal administration in 2015. The methodology addresses the concept of urban territorial accessibility as a model for evaluating the impact generated by road interventions proposed by the Plan in the short term, once they are built. Digital tools are used (ArcMap, Microsoft Excel, TransCad) and socio-economic variables (area, population, housing) are introduced into the analysis. As a main result, it is found that the road interventions proposed in the plan, generate a shorter access time to the northern, southern and western sectors of the municipality. This leads to conclude that the proposed interventions are adequately addressed from the point of view of decreasing average travel times.

Keywords : accessibility; infrastructure; coverage; travel time; saving gradient.
