| Summary: | This paper proposes a methodology to
prioritize interventions in Peru's road network. A
network model is built, linking the country's economic
and population centers through indicative corridors, which
are defined as the least-cost routes to connect origins to
destinations. The network's critical links are
identified by systematically simulating disruptions and
calculating the costs associated with them. The network is
then overlaid with natural hazard layers. The average annual
losses associated with the hazard disruptions of the
critical links are calculated in many scenarios, including
climate change uncertainty and different impacts and
reconstruction times. A robust decision-making approach is
then used to select interventions that decrease hazard
disruption costs. |
