  1. 11. Three essays on transport CBA uncertainty

    Författare :Peter Almström; Anders Karlström; Svante Berglund; Westin Lars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost-Benefit Analysis; Transport planning; Land-use planning;

    Sammanfattning : Cost Benefit Analysis (CBA) has for a long time been used in transport planning, but it is often questioned. One main argument against CBA is that the results depend largely on assumptions regarding one or a few input factors, as for example the future fuel price or valuation of CO2 emissions. LÄS MER

  3. 12. Mobility Knowledge Graph and its Application in Public Transport

    Författare :Qi Zhang; Zhenliang Ma; Erik Jenelius; Carlos Lima Azevedo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge graph; Smart card data; Public transport; User-station attention; Relation extraction; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Sammanfattning : Efficient public transport planning, operations, and control rely on a deep understanding of human mobility in urban areas. The availability of extensive and diverse mobility data sources, such as smart card data and GPS data, provides opportunities to quantitatively study individual behavior and collective mobility patterns.

  4. 13. Recovery actions in freight transport through real-time disruption management

    Författare :Per Wide; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; freight transport; transport system; operational planning; proactive recovery actions; Disruption management; real-time information;

    Sammanfattning : This thesis focuses on the management of disruption in freight transport. The management of disruption is of importance to achieve planned efficiency in the transport system by mitigating or avoiding the impacts of disruptions, such as late arrivals of deliveries. LÄS MER

  5. 14. Urban freight transport sustainability - the interaction of urban freight and intermodal transport

    Författare :Sönke Behrends; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modal shift; urban sustainability; transport planning; pre- and post haulage; rail freight; sustainable freight transport; Framework for Strategic Sustainable Development; urban freight transport; longer and heavier vehicles; intermodal road-rail transport;

    Sammanfattning : Intermodal road-rail transport (IRRT) has a significant urban dimension that affects the environmental benefits and the modal shift potential of rail freight. A sustainable modal shift, i.e. LÄS MER

  7. 15. On optimal mission planning for conventional and electric heavy duty vehicles

    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; Logistics planning; Transport efficiency; Mission planning; Optimal control; Eco-driving; Model predictive control;

    Sammanfattning : Ever-growing energy consumption and CO2 emissions due to the increase in road transport are major challenges that attract international attention, especially policy makers, logistic service providers and customers considering environmental, ecological and economic issues. Other negative side-effects caused by the growth of the road transport are the extensive economic and social costs because of traffic congestion. LÄS MER
