Utvikling av en helhetlig metode for analyse av 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. Dette er den norske oversettelsen/tilpasningen av The reliability and vulnerability of transportation lifelines, skrevet av Jan Husdal ved University of Utah, Salt Lake City, USA, i 2002. Videreutviklet i 2008: Er rassikring lønnsomt?

The reliability and vulnerability of transportation lifelines

ResearchBlogging.orgHow can we assess how reliable or vulnerable the transportation is, and which parameters can we apply  in measuring reliability and vulnerability? 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. This research essay takes a closer look at vulnerability and reliability issues in transportation networks.

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. The neighborhood that needs to be examined is dependent on the hazard and its contributing factors. This neighborhood search then produces a hazard map that is directly related to the road.

Shortest Path Computation: A Comparative Analysis

Current research work into establishing a performance efficiency hierarchy between Java, C++ and ArcView is described and experimentation is performed in order to statistically compare shortest path query execution time, response time and implementation issues.
