Norwegian roads are dangerous!

rv70 Oppdølstranda

In a recent study undertaken by the Molde Research Institute in Norway, a point is made that the typical socio-economic impact of road network disruptions in Western Norway varies greatly, depending on a) the traffic volume, b) the actual possibilities of rerouting traffic and c) the composition of the traffic that uses the impacted road.

Accessibility Index - a measure of Transport Network Vulnerability?

Taylor, M., Sekhar, S., & D'Este, G. (2006). Application of Accessibility Based Methods for Vulnerability Analysis of Strategic Road Networks Networks and Spatial Economics, 6 (3-4), 267-291

The starting point for this paper is the question of how to define and find critical locations in a transport network. A network node is vulnerable if loss or degradation of a small number of links diminishes the accessibility of the node. A network link is critical if loss or degradation of the links diminishes the accessibility of the network or of particular nodes [ ... ]

Utvikling av en helhetlig metode for analyse av pålitelighet og sårbarhet av transportsystemer

nou-kritisk-infrastruktur

Transportsystemer som veg og jernbane danner ryggraden i et moderne samfunn. Påliteligheten og sårbarheten i et transportsystem blir dermed avgjørende faktorer ikke bare i konkurranse- og markedsøyemed, men også i beredskapssammenheng, for å kunne opprettholde normal samfunnsdrift. [ ... ]

The reliability and vulnerability of transportation lifelines

critical-infrastructure

Transportation networks like freeways and interstate highways are the main backbone of modern society. Consequently, the reliability or vulnerability of any transportation network is thus a decisive factor not only in terms of market outreach and competition, but also in terms of continuity, to ensure a 24/7 operation of the community we live in.

A spatial framework for modeling transportation hazards

javalanche

Transportation networks are exposed to a wide range of natural hazards and this study has developed a GIS tool for analyzing these hazards. The primary hazards included in this study are avalanches, landslides, flooding, earthquakes, wildfires, and rockfall. The GIS software used was MFWorks [ ... ]
