“…Zhou et al (2010) calculated the social costs of drive delay and loss of opportunity caused by degraded network under a set of earthquake scenarios in order to evaluate the social-economic effect of seismic retrofit of bridges. Sohn et al (2003) evaluated the significance of several bridges by quantifying the economic losses due to the 1812 New Madrid earthquake. Postance et al (2017) conducted economic estimation for scenarios of road segments disruptions simply by multiplying increasing travel time with national user generalized cost without considering any ripple effects of transportation disturbances.…”

Civil infrastructure systems are disturbed by natural or man-made hazards at an increasing frequency and severity. Among these systems, transportation systems are especially vulnerable due to their nature and are of significant importance to urban built environments as they maintain the mobility of urban dwellers and goods. Mobility disturbances are significant not only due to the direct losses associated but also due to the greater economic impacts driven by indirect losses stemming from the economic interactions of regions and sectors. Therefore, understanding the economic impacts of urban mobility disturbances is critical. To achieve a better understanding of the status quo of the research on transportation disturbances and economic impact analysis, a literature review was conducted. The review indicates that most of the articles fail to leverage realistic hazard impact information and explicit network modeling, consequently jeopardizing the credibility of the results. To begin addressing the gaps in the field, an interdisciplinary framework was designed to investigate the economic impacts of mobility disturbances. To validate the framework, a case study was conducted to estimate the economic impacts of commuting-based mobility disturbances resulting from a potential earthquake scenario in the Greater Los Angeles Area. The direct and indirect economic losses were estimated to be 285.49 and 93.48 million dollars, respectively. The results indicated that the economic losses could vary significantly among regions as well as industries. Among the five counties in the study region, Los Angeles County suffered the most. In addition, industries related to finance, education and scientific services, etc. were estimated to experience larger losses.

While cities continue to cast a large environmental imprint on their regionally proximate environments, they are also exerting a stronger influence on the natural systems of more remote locations because of their growing interconnectedness and interdependence with other citiesin a word, globalization. This paper reviews some of the characteristic features of globalization and its environmental impacts. It also discusses possible responses to these developments and focuses in particular on the critical role that urban infrastructure systems can play. The paper concludes with a discussion of how one might conduct analyses supporting the management of changes in urban infrastructure systems to lighten urban environmental imprints.

“…Basically, these losses can be measured by the repair or replacement costs of the damaged structure and properties, including building contents and business inventory (Brookshire et al, 1997;Lindell and Prater, 2003;Enke et al, 2007;Commission on Geosciences, Environment and Resources, 1999;An et al, 2004;Chen et al, 2005;Sohn et al, 2003;Federal Emergency Management Agency 2001).…”

Destruction from natural and man-made disasters can result in extensive damage to the affected area's infrastructure. While the destruction results in costs that are necessary to restore the physical destruction and repair of existing infrastructure, a wider economic impact is often indirectly measured and felt. Policy-makers generally focus only on losses that are directly caused by the destruction, such as the replacement of roads and bridges, yet tend to overlook the consequences from indirect economic losses. This study proposes a framework to estimate the indirect economic loss due to damaged bridges within the highway system of a major metropolitan area. For the research, a simulated earthquake within the St. Louis metropolitan region is selected as a case study. The computable general equilibrium (CGE) model is applied as the loss estimation tool for modeling the indirect cost. The study results show that the indirect loss is significant when compared to the direct loss and should therefore be considered by policy-makers when making both pre-and post-disaster infrastructure decisions.
