Economic Loss Assessment due to Railroad and Highway Disruptions

Abstract

This paper aims to present an illustrative case study on the economic impacts of transport infrastructure disruptions caused by the hypothetical Tokai-Tonankai earthquakes in Japan. We formulate a spatial computable general equilibrium (SCGE) model, which integrates a transportation model that can estimate two types of interregional flows of freight movement and passenger trips. The case study shows the impacts of transportation disruptions and the importance of network redundancy with transport-related economic losses corresponding to several scenarios from disasters and network levels of development.
