Abstract
The measurement and mapping of transportation network vulnerability to natural
hazards constitute subjects of global interest for a sustainable development
agenda and as means of adaptation to climate change. During a flood, some
elements of a transportation network can be affected, causing the loss of lives.
Furthermore, impacts include damage to vehicles, streets/roads, and other
logistics services - sometimes with severe economic consequences. The
Network Science approach may offer a valuable perspective considering one
type of vulnerability related to network-type critical infrastructures: the
topological vulnerability. The topological vulnerability index associated with an
element is defined as reducing the network’s average efficiency due to removing
the set of edges related to that element. In this paper, we present the results of a
systematic literature overview and a case study applying the topological
vulnerability index for the highways in Santa Catarina (Brazil). We produce a
map considering that index and areas susceptible to urban floods and
landslides. Risk knowledge, combining hazard and vulnerability, is the first pillar
of an Early Warning System and represents an important tool for stakeholders of
the transportation sector in a disaster risk reduction agenda.
