Abstract: Other than the direct exposure of a seismic event, the interruption of the transportation network causes an indirect exposure of the population living in stricken areas. In spite of such evidences, current planning practices rarely address road network seismic risk concerns beyond the typical structural link-by-link approach. The underlying hypothesis of the current research work is that, when facing a major earthquake, the impacts on road networks performance for emergency response functions can be minimized namely by the introduction of measures, not only in terms of infra-structural reinforcement but also in terms of network connectivity and activities location. Potential applications of this work include urban planning micro and macro scale solutions to be included in specific instruments (such as urban master plans or emergency plans). Additionally, the proposed method may be integrated in loss estimation models, which still do not include earthquake losses due to inaccessibility.
