Item Estimating the resilience of, and targets for, a transport system using expert opinion(2021-12) Martani, Claudio; Adey, Bryan T; Robles, Ignacio; Gennaro, Federico di; Pardi, Livia; Beltran-Hernando, Iñaki; Toribio-Diaz, Concepcion; Redondo, Noemi Jimenez; Díaz, Adrián Antonio Moli; Tecnalia Research & Innovation; E&I SEGURAS Y RESILIENTESTo ensure that transport infrastructure provides acceptable levels of service with respect to extreme events, the resilience of the infrastructure needs to be estimated and targets for it need to be set. Recent work in the European research project Future Proofing Strategies for Resilient Transport Networks against Extreme Events (Foresee) has shown how this can be done in situations with a wide range of available data, time frames for the estimation and expertise. This paper provides an example of how an infrastructure manager can use the guideline to estimate the resilience of, and set resilience targets for, an example transport system in a relatively short period of time, even in the case of limited expertise in all the relevant areas and limited knowledge and information on all the basic input variables. The example is fictive but realistic. It is based on a transport system consisting of a section of the A16 highway, in Italy, where a potential landslide could discharge enough material to damage road sections and bridges. The resilience is estimated using resilience indicators with differentiated weights, and the resilience targets are set using cost–benefit analysis, to identify the indicators to be improved first.Item Estimating, and setting targets for, the resilience of transport infrastructure(2021-07-30) Adey, Bryan T; Martani, Claudio; Kielhauser, Clemens; Robles, Ignacio Urqulijo; Papathanasiou, Natalia; Burkhalter, Marcel; Beltran-Hernando, Iñaki; Garcia-Sanchez, David; Tecnalia Research & Innovation; E&I SEGURAS Y RESILIENTESTo ensure that transport infrastructure provides acceptable levels of service with respect to extreme events, the resilience of the infrastructure needs to be estimated and targets for it need to be set. In this paper, the methodology proposed in the Foresee EU research project is presented. The methodology allows managers to measure, and set targets for, the resilience of transport systems in all situations. It requires clear definition of the transport system and how the service provided and the resilience are to be measured. The methodology allows consideration of the fact that transport infrastructure managers need to estimate resilience with various degrees of accuracy depending on the specific problem to be addressed, the time frame at disposition and the expertise available. These various levels of accuracy are covered by proposing the use of (a) simulations, (b) indicators whose values are directly related to increases in expected restoration intervention costs and reductions in service, and (c) the percentage of fulfilment of indicators. Once resilience has been estimated, the methodology provides guidance on how to set resilience targets with or without cost-benefit analysis. For demonstration, the explanation of the steps of the guideline is supported by their use for a simple transport system.
