​D2.3 Vulnerability and Resilience Factors

Download pdf


The scope of this deliverable is to analyse vulnerability and resilience factors affecting a loss of mobility in terrestrial transportation network caused by natural events. The focus is on assessment of the probability and severity of loss of mobility due to natural hazards that are considered as the most critical in the pilot countries. The assessment was done using structural and functional vulnerability functions, which are associated with failure modes of an infrastructure asset and a specific hazard type. The occurrence of a mobility loss is analysed at the level of an asset. Consequences of the mobility loss are analysed considering a transportation network and the functions it serves. The background is given on the key factors for resilience: robustness, resourcefulness, rapid recovery and redundancy. 

The review of existing structural and functional vulnerability functions that was performed showed that vulnerability functions are lacking for many types of hazards and assets. Therefore, recommendations for developing vulnerability functions have been made. Each vulnerability function is governed by properties of an asset and/or location for which it was developed. It is suggested to consider intensity parameters for different types of hazards, methods for developing the functions and the assessment of the relationship between structural vulnerability of an asset and functional vulnerability. 

The deliverable also reviews the factors affecting the consequences of a mobility loss. These factors are related to the redundancy of the network and the time for recovery after the occurrence of a natural event.
