Pålitelighet og sårbarhet – et ikke-tema i nyttekostnadsanalyser?

Pålitelighet og sårbarhet er to forhold av betydning for transportbrukere som i dag ikke tas hensyn til i vurdering av samferdselsprosjekter. Hvorfor er slike vurderinger ikke med når vegprosjekter blir vurdert?

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

How to make a straight line square

Traditionally, network analysis, path finding and route planning have been the domain of graph theory and vector GIS, which is where most algorithms find their application. Contrary to such common wisdom, the research of this thesis for the Msc in GIS explores the topic of network analysis in raster GIS, using MFworks as example software.
