영문 초록

Road network is the backbone of the safety and livability of the human beings. However, the frequent extreme weather events are currently threatening its stability and resiliency. Between 1999 and 2008, the property loss in infrastructure related to roads account for 90% of the total loss in Korea. Thus, maintaining the function of the road network and increasing its resilience with the occurrence of any extreme weather events has become an important agenda at the national and local level. The road network consists of nodes and links, which are cross sections and streets respectively. In this research, we assess the vulnerability of the road network in Seoul towards flooding, using centrality indices in network theory. The centralities of the nodes in flood prone areas have been compared with those of general nodes in Seoul. The results demonstrate that the nodes in the flood prone areas tend to have higher centrality indices, implying their important and influential roles in the function of the overall road network. The results call for the immediate attention on the vulnerable roads in the management and operation of the road network in Seoul.
