La vulnérabilité structurelle des réseaux de transport dans un contexte de risques

Abstract : The increasing importance of natural and technological disasters have lead societies to take an interest in the risks prevention and prediction. A way to reduce risks consists in reducing the vulnerability of the threatened items, that is their propensity to be damaged. Among these items, the transport networks are particularly interesting because they are threatened not only in a material way (damaging to the infrastructure), but also in a functional way (damaging to the use) through the damaging to their structural properties (the relational oppurtunities offered by the networks).
In order to understand and to forecast the functional disturbances of a transport network threatened by a disaster, it is relevant to define and evaluate the vulnerability of its structure – that is of the networks lattice out of any use consideration – and to understand the underlying relational organization. In that respect, we first have to build a framework adapted to such a structural study, that is to define the data structure, the assumptions, the modelisation choices and the necessary tools.
Then, we propose a definition of the vulnerability and we develop tools for its evaluation and its caracterization. According to the interests and the limits of such tools, we propose at last to improve the caracterization of the vulnerability by highlighting the structural properties which explain the different vulnerability levels on the network. This research is lead on several real networks which bring up various scales and whose features are interesting within a risk context (the inner Paris underground and the road networks in the french town of Orléans and on the french and european territories).
