Konferensbidrag (refereegranskat)abstract
- The reliability and vulnerability of critical infrastructures have attracted a lot of attention recently. In order to assess these issues quantitatively, operational measures of the importance of links and the exposure of sites in infrastructure networks are needed. Such measures can also be used as a guidance to road administrations in their prioritisation of maintenance and repair of roads, as well as for avoiding causing unnecessary disturbance in the planning of road work. In this paper, several link importance indices and node exposure indices are derived based on the increase in generalised travel cost when links are closed. These measures are calculated for the road network of northern Sweden. Results are collected in a GIS for visualisation, and are presented per link and municipality.
