An integrated model of bridge performance, highway networks, and the spatial metropolitan economy : Towards a general model of how losses due to earthquake impacts on lifelines affect the economy

ABSTRACT

We summarize an integrated model of losses due to earthquake impacts on transportation and industrial capactiy affect the urban economy. The procedure advances transportation and activity system analysis techniques in ways that help capture the most important economic implications of earthquakes.Network costs and origin/destination requirements are endogenous and consistent. Indirect and induced losses associated with direct impacts on transportation and industrial capacity are distributed across zones and economic sectors. This study of the tansportation network is suggested as a template for studying the full range of losses associated with other lifeline impacts. (AU)
