Economic impacts of transportation network changes: Implementation of a combined transportation network and input-output model

Abstract

This article estimates and evaluates the economic impacts from a catastrophic earthquake within regional and national contexts, emphasising the inter-industry relationship in conjunction with regional commodity flows and the assessment of seismic damages on a transportation network. The analytical methods employed are twofold: a multi-regional input-output model and a regional commodity flow model.Using the above analytical framework, the economic impacts from a catastrophic earthquake are estimated and evaluated based on hypothetical scenarios of the event, by analysing the magnitude and extent of direct and indirect impacts. Furthermore, as possible extensions, the models developed here can be used as tools for strategic management of the recovery and reconstruction efforts after the event. JEL classification: R41, R53

Vulnerability and resilience of transport systems – A discussion of recent research

“…Notably, several authors have assessed the economic impacts of earthquakes disrupting the road network using integrated transport network and multiregional trade models (Cho et al, 2001;Ham et al, 2005;Kim et al, 2002;Tatano and Tsuchiya, 2008). Bono and Gutiérrez (2011) use network theory and GIS-based analysis to evaluate the impacts of disrupted roads on accessibility following the earthquake that hit Haiti in 2010.…”

“…With more information, caps on zonal production can be applied. Moreover, congestive feedbacks may be incorporated in travel cost estimates (e.g., Zhao and Kockelman, 2003;Kim et al, 2002), if background flow values (from other network users) are known (or modeled endogenously), commodity flows are converted to truck and train flows, and origin and mode choice models are calibrated with respect to travel time and cost. (Travel time and cost variables are not available in the Commodity Flow Survey, but may be estimated or obtained for certain sectors based on othersÕ research.)…”

Road project opportunity costs subject to a regional constraint on greenhouse gas emissions

“…Other approaches analyse more finely effects of transport networks as these networks are altered (Kim et al, 2002;Ham et al, 2005) or in connection with biofuels (Neuwahl et al, 2008). The issue of GHG emissions associated with transport is analysed in terms of ecological footprint (Druckman and Jackson, 2009).…”
