GRADILLA-HERNANDEZ, L.A.; DE LA LLATA-GOMEZ, R  e  GONZALEZ-GOMEZ, O. Measures of Road Network Vulnerability. Recent Approaches and a Proposed Application in Mexico. Ing. invest. y tecnol. [online]. 2011, vol.12, n.3, pp.257-267. ISSN 2594-0732.

In this paper, the integration of a multicriteria analysis methodology that enables identification of critical road network links that can be applied to Mexico is proposed. In order to achieve this, recent works about road network vulnerability are reviewed in this article and their main findings are analyzed. It was found a concept of vulnerability accepted by some authors, where vulnerability is related to the consequences of link failure, irrespective of the probability of such failure. Some cited works, propose to take into account the road link capacity in vulnerability analysis, for that reason it is included in the proposed methodology. Finally, an exercise using a hypothetical network is made and a multi-criteria model is described.

Palavras-chave : transport system; road network; link interruptions; vulnerability analysis; critical link; multicriteria analysis.
