  1. 26. 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

  3. 27. The knowledge problem of public transport policy

    Författare :Erik Johansson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Planning; Appraisal; Evaluation; Public transport; Planning; Appraisal; Evaluation;

    Sammanfattning : The overall aim of the thesis is to investigate the knowledge problem in regional public transport planning. The knowledge problem is twofold. How do transport policy arrive at the desirable actions they take and how do they assess the alternatives, and what can we say about the contributions of already implemented transport schemes.

  4. 28. A sustainability perspective on urban freight transport: Factors and incentives affecting local authorities in the planning procedure

    Författare :Maria Lindholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable transport; urban freight transport; freight transport planning;

    Sammanfattning : Freight transport has a minor role in the transport planning procedures in most cities, although the transport operations of freight represent a heavy part of important emissions. Earlier studies in the area show that there is an existing problem mainly based on literature reviews and discussion groups. LÄS MER

  5. 29. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports

    Författare :Ingrid Johansson; Markus Bohlin; Oskar Fröidh; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy-duty vehicle platooning; road traffic simulation; intelligent transport systems; optimal control; longitudinal cruise control; fuel economy; railway traffic simulation; microscopic simulation; macroscopic simulation; freight trains; early departures; capacity; railway stations; strategic planning; timetable compression; UIC Code 406; Transportsystem; Transport Systems;

    Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER

  7. 30. The Public Transport Preferences of Elderly People; A study related to individual capacity and environmental stress in service route traffic and other systems

    Författare :Helena Svensson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walking distance; valuation; standard factors; conjoint analysis; stated preference method; trunk routes; special transport; service routes; restrictions; physical capacity; preferences; travellers; public transport; elderly people; traffic planning; Road transport technology; Vägtransportteknik;

    Sammanfattning : Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. LÄS MER
