Abstract

This paper presents a synthesis of the state-of-the-art on transportation network resilience. The socio-technical approach associated with resilience evaluation is broad and multidisciplinary, focusing on the network's ability to sustain functionality and recover speedily after disruptions. The three key problem areas identified in literature were: minimal network-level study applications of resilience; insufficient practical methods in quantifying the recovery phase of resilience; and the need for the development of resilience indexes demonstrated on real-life regional network models. The authors of this paper recommend that: further investigative efforts are directed towards the post-disaster phases of resilience; evaluating the applicability of resilience indexes on multiple hazard events for transportation networks is requisite; and the formulation of resilience indexes based on regional network models and variable demand traffic assignment models. Furthermore, collaborative efforts between management authorities and researchers are necessary to facilitate the advancement and enactment of necessary policies to enhance transportation systems' resilience.
