  1. 1. Mode choice modelling of long-distance passenger transport based on mobile phone network data

    Författare :Angelica Andersson; Maria Börjesson; Ida Kristoffersson; Clas Rydergren; Leonid Engelson; Jonas Westin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand model; Mode choice; Latent class; Mobile phone network data; Travel behaviour; Long-distance travel;

    Sammanfattning : Reliable forecasting models are needed to achieve the climate related goals in the face of increasing transport demand. Such models can predict the long-term behavioural response to policy interventions, including infrastructure investments, and thus provide valuable pre-dictions for decision makers. LÄS MER

  3. 2. Issues in Estimation and Application of Long Distance Travel Demand Models

    Författare :Muriel Beser Hugosson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intercity travel; logit model; market segments; stated preference; bootstrap; heteroscedastic extreme value model; nested logit;

    Sammanfattning : Forecasts of the demand for long distance travel areessential for many decisions, such as infrastructureinvestments, operators´management policies etc. Manyresearch issues are related to this field, and the purpose ofthis thesis is to contribute to some of them. LÄS MER

  4. 3. Time and energy in long-distance bird migration

    Författare :Thord Fransson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

    Sammanfattning : Long-distance seasonal migration is energetically demanding and time consuming. For example, some passerine birds are on migration during six months of the year, travel more than 10 000 km and make use of many fuelling sites. Migration requires many different decisions, and an individual bird will face a variety of situations. LÄS MER

  5. 4. On Optimal Mission Planning for Vehicles over Long-distance Trips

    Författare :Ahad Hamednia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic dynamic programming; Optimal control; Logistics planning; Thermal and charging management; Model predictive control; Mission planning;

    Sammanfattning : This thesis proposes a mission planner for vehicles over long-distance trips, for finding the optimal trade-off between trip time, energy efficiency, and driver comfort, subject to road information, traffic situations, and weather conditions. The mission planner consists of three components, i.e. LÄS MER

  7. 5. Telecommuting's implications on travel and travel patterns

    Författare :Jo Skåmedal; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Telecommuting; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : The subject field is within technology and social change, with focus particularly on telecommuting and the possible changes that arises in the travel patterns as a result of the telecommuting situation. When a person starts working from home once or twice a week instead of commuting back and forth to the main work place, a number of changes in the telecommuters' distribution of travel can and most probably will arise.
