Abstract

This paper demonstrates the quantification of the resilience index (RI) in transport systems. The transport infrastructure can be managed by using the concepts of resilience. Vugrin, Warren, Ehlen, & Camphouse (2010) emphasized the enhancement of resilience in infrastructure before disasters and the establishment of efficient measures for the recovery of systems in an emergency. The concept of resilience has a significant influence on transport planning and operations for disaster preparation. Lee, Kim, & Lee (2013) investigated the concepts of resilience and examined case studies using valuable asset-management techniques in order to maintain the resilience concepts which should be introduced in transport infrastructure planning and operations. Therefore, this paper presents the RI based on Vurgrin et al. (2010) and Lee et al. (2010).

The first part of this paper focuses on the measurement of the RI using the recovery-dependent resilience (Vugrin et al., 2010) in transport infrastructures. For quantifying the RI, we have developed various variables that are used to target an achievable or a desired system performance in disaster recovery efforts. The second part of this paper focuses on the applications of the RI in case studies. The examined cases are road networks in flooded areas, heavy snowfall districts, and landslide occurrence zones. Each case is analyzed for transport costs both under normal and disaster conditions using the transport demand estimation models. Finally, we quantify the RI, which is important for establishing the provision of safety, recovery, and rehabilitation of transport infrastructures in flooding, snowfall, and landslide areas.
