Abstract
This paper presents a methodology for integrating vulnerability due to natural hazard into current infrastructure management systems. It is mainly concerned with presenting a methodology to assess link failure induced transportation related consequences including congestion related effects across a national network. The main challenge hereby considered is how to overcome the calculation time intensity of this equilibrium-based via equilibrium. Rather than employing the complete network for analyising a link failure, subnetworks are employed to model the spatially restricted demand shifts effects around a failed link. Each subnetwork is formulated by cutting a geographically defined selct of links and nodes out of the national network and including the internal and external demand transversing the subnetwork boudary. The failure consequences, even for links with long path distances or long detours, assessed with the subnetwork are very consistent with those considering the full network. A statistical model, highlighting and detailing the key factors defining transport related consequences, is developed from the computed link failure consequences and link parameters. Lastly, the findings highlight the potential gains to be derived from directly including rail networks and covering the potential mode shifts in the assessment. Show more
