Our ‘hotspot’ analysis identified critical infrastructure locations (pdf, 200 KB), measured by the number of directly or indirectly dependent customers for Infrastructure UK (IUK), a unit within HM Treasury.
Through an extensive database of details from interdependent networks, we examined the nation-wide crisis points of individual infrastructures. The final analysis involved national-scale networks for electricity transmission and distribution, gas, trunk road and rail, and demonstrated that failure at a particular location could result in a cascade of effects and disruption.
The hotspot analysis also features in a University of Oxford case study, Getting critical (pdf, 310 KB).
