Pålitelighet og sårbarhet av transportsystemer

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

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.

JavalancheTM – analyzing hazards to roads

Traditionally, in studying the effect of hazards on roads, a hazard map is prepared based on the hazard in question, the contributing factors and then overlaid with a road map. If the road or a buffer around its vicinity intersects hazard areas, these areas constitute a potential threat. In the approach used in this procedure, imagine traveling along the road and looking to either side for hazards.

A spatial framework for modeling hazards to transportation lifelines

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

Book review: Networks and Algorithms

This book tells you the difference between the various types of graphs, trees and networks and shows you step by step calculations on how to solve them by hand (they didn’t have that many computers in 1993).
