Review of studies on the resilience of urban critical infrastructure networks

Abstract

With the rise of the resilience concept, scholars and practitioners have paid increasing attention to resilient city, which has become a new means of coping with hazards. As the cornerstone of modern cities, urban critical infrastructure networks (CINs) are prerequisites for resilient cities due to the huge economic losses and social impacts caused by their incapacities. In recent years, researches on the resilience of CINs have considerably increased, resulting in various resilience definitions, approaches, and enhanced strategies. This work reviews literature on six CINs, namely, water, drainage, gas, transportation, electric, and communication networks. The resilience definitions, hazard categories, methodologies, and enhanced measures for each CIN are analyzed in detail. Research challenges and future directions are also presented.
