A Quantification of Disaster Damage Costs Based on a Resilience Triangle
The purpose of this study is to find a way of quantifying of disaster damage costs based on a resilience triangle concept.The data used in calculating the damage costs are from Vehicle Detector Systems in the road networks of Gyeongju City and Ulsan City where the actual disasters of earthquakes and flooding have been occurred respectively.Travel times before and after disasters have been compared and analyzed to calculate the damage costs of these disasters.Reduction ratios of traffic speeds in urban traffic systems before and after the disasters have been analyzed to see how the resilient triangle concept can be applied for these studies.Using the Resilience Triangle of M.Bruneau(2003),we have derived a linear function of damage recovery capacities and damage scales of transportation systems.We have quantified the damage scales,and constructed a calculation methodology of disaster damage costs based on the resilience triangles.We expect this resilient triangle concept has a play a role to reduce these kinds of natural disasters in future.
