Abstract
We developed a model for evaluating the effects of functional impairment of road networks due to seismic damage, based on the data from the 1995 Hyogo-ken Nambu Earthquake. The effects of functional impairment of road networks on various sectors were analyzed to clarify the relationship between functional impairment of road networks due to a seismic event and seismic damage to road networks. Functional impairment due to seismic structural damage to road networks was modeled as a functional impairment matrix. Combining the model of seismic damage effects with the functional impairment matrix, we assessed the cost of the functional impairment associated with the Hanshin Expressway Route 3.
