1. 1. Godskunders värderingar av faktorer som har betydelse på transportmarknaden

   Detta är en avhandling från Transporter och samhällsekonomi

   Författare :Sofia Lundberg; KTH.; [2006]
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The purpose of this project was to determine the freight customers’ valuations that are im-portant to their choice of transport mode for long-distance freight transportation. The results are intended to form the basis for valuations of changes in the transport system and for fore-cast models. LÄS MER

3. 2. Framework for Estimating Congestion performance measures : case study of Stockholm

   Detta är en avhandling från Transporter och samhällsekonomi

   Författare :Carlos A. Morán Toledo; KTH.; [2008]
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : For operational and planning purposes it is important to observe and predict the traffic performance of congested urban road links and networks. Congestion can be defined as traffic conditions caused by a downstream bottleneck or excess in travel time from what is incurred during light or free-flow travel conditions. LÄS MER

4. 3. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

   Detta är en avhandling från Transporter och samhällsekonomi

   Författare :Yuriy Reshetyuk; KTH.; [2006]
   Nyckelord :terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

   Sammanfattning : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. LÄS MER

5. 4. Quantitative vulnerability analysis of electric power networks

   Detta är en avhandling från Stockholm : KTH

   Författare :Åke J. Holmgren; KTH.; [2006]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys;

   Sammanfattning : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. LÄS MER

7. 5. Analysing Sustainable Urban Transport and Land-Use : Modelling tools and appraisal frameworks

   Detta är en avhandling från Stockholm : KTH

   Författare :R. Daniel Jonsson; KTH.; [2008]
   Nyckelord :sustainable development;

   Sammanfattning : Sustainable development and climate change is high on the agenda for most cities around the world today. Urban transport is at the heart of these changes. Increasingly, it is recognised that not only is the emission of pollutants and greenhouse gases a problem, but also the detrimental effects of congestion and social exclusion. LÄS MER
