Functional Damage and Recovery of Highway Networks in Major Earthquake Disasters in Japan
Publication: Lifelines 2022
ABSTRACT
We evaluated the post-earthquake functional damage and recovery of highway networks in Japan using dataset obtained from major earthquake disasters during the period of 1995–2018. Firstly, the spatial extents of road closure were compared for four earthquakes in conjunction with corresponding seismic intensity distributions. On this basis, serviceability fragility functions, describing the relationship between shaking intensity and the probability of occurrence of road closure, were developed for each earthquake. It was found that the functions reflect traffic control criteria and related rules in highway companies. Secondly, spatiotemporal recovery processes of daily traffic volumes were compared for three earthquake disasters. Highway network performance was then compared in terms of three kinds of measures: (1) total number of sections open to traffic, (2) total distances open to traffic, and (3) total traffic volumes weighted by travelled distance. The third measure tends to be lower than the other two. Serviceability measure reflecting traffic volumes should be used in evaluating damage and restoration of highway networks.
