Socioeconomic Dimensions of Resilience to Seaport and Highway Transportation Network Disruptions

Serving as a critical portal of the nation’s supply-chain, seaports and its associated transportation infrastructure, such as bridges and highways, are especially vulnerable to disruptions from a variety of causes, including but not limited to natural disasters, technological accidents, cyber breaches, and terrorist attacks. The economic impacts of these incidents can be extensive well beyond the on-site operations at the port complex, through the supply-chain effects of the disruptions and/or delays of delivering imports and exports from ports to their destinations and vice versa. The proposed research will build on prior work of the principal investigators in analyzing the impacts of port disruptions and the role of resilience -- ways to reduce the impacts of disruptions to imports and exports through such tactics as ship rerouting, use of excess capacity at the port, use of inventories, conservation, supply-chain realignments, and rescheduling of economic activities. The added contribution of this project will proceed along two dimensions. First, to fill in an important gap in the port and transportation network disruption literature, we will examine not only the impacts of port and transportation network disruption and the effectiveness of resilience tactics across economic sectors, but also across socioeconomic groups. Thus, the focus will not only be on how various types of businesses cope with import and export disruptions, but also how various consumer income groups cope with supply shortfalls of household goods and associated price increases. To perform this additional layer of analysis, we will integrate a multi-sector income distribution matrix into the economic analysis following the work of Rose and Oladosu (2002), Oladosu and Rose (2007), and Rose et al. (2012). Second, to derive accurate estimates of the socioeconomic impacts of disruptions to the port and associated transportation infrastructure, we will establish a formal linkage between the socioeconomic impact model and a transportation network model. The modeling will be applied to a simulated earthquake scenario that affects commodity flows in and out of POLA/POLB and the associated inland highway transportation network.
