Descripción
La presente investigación consiste en un análisis sistemático y multiescalar de los posibles riesgos de la red vial colombiana, buscando desarrollar un sistema de detección y cuantificación con el propósito de mejorar la gestión de los recursos destinados a las obras de infraestructura vial. Se realizó un diagnóstico de la red vial colombiana a partir de la teoría de grafos. Tras analizar la posición relativa de los asentamientos, se encontró un fenómeno de centralidad, el cual se profundiza en el análisis particular de Antioquia, departamento en el que se buscó dimensionar la influencia de la conectividad vial sobre variables demográficas, económicas y sociales. Se encontró una mayor correlación en lo económico que en lo demográfico. Posteriormente, se realizaron dos análisis de impacto topológico-económicos, ambos sobre el corredor vial del Túnel de la Línea. El primero consistió en medir el impacto local de la construcción de la obra de infraestructura, y el segundo, en evaluar el impacto regional del cierre del corredor, resultando en una mejora del 2,54% en la accesibilidad en el primer caso, y una disminución del 1,96% en el segundo caso.
The present research consists of a systematic and multiscale analysis of the possible risks of the Colombian road network, seeking to develop a detection and quantification system with the purpose of improving the management of resources destined for road infrastructure works. A diagnosis of the Colombian road network was carried out based on graph theory, and after analyzing the relative position of the settlements, a centrality phenomenon was found. This will be delved into in the particular analysis of Antioquia, the department in which the influence of road connectivity on demographic, economic, and social variables was measured, finding a greater correlation in the economic than in the demographic. Subsequently, two topological-economic impact analyses were carried out, both on the Tunel de la Línea road corridor. The first consisted of measuring the local impact of the construction of the infrastructure work, and the second, of the regional impact of the closure of the corridor, resulting in a 2.54% improvement in accessibility in the first case, and a decrease in accessibility by 1.96% in the second case.
