  1. 1. Electric vehicles in action

    Författare :Martina Wikström; Per Alvfors; Lisa Hansson; Gil Tal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; interdisciplinary approach; public fleets; public transport;

    Sammanfattning : This thesis analyses the political and practical conditions for introducing electric vehicles in Swedish public authorites and discusses the potential for using electric vehicles in public transport and public fleets. The work has been carried out using an interdisciplinary research approach. LÄS MER

  3. 2. Distributed optimization for the optimal control of electric vehicle fleets

    Författare :Rémi Lacombe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Optimal control; Electric vehicles; Public transit; Distributed optimization;

    Sammanfattning : Owing to their absence of tailpipe emissions and their independence from fossil fuels, Electric Vehicles (EVs) are currently experiencing a rapid deployment in an attempt to curb global greenhouse gas emissions. EV operation represents a technical challenge, however, as new control algorithms need to be developed to address their limited driving range and their longer charging times. LÄS MER

  4. 3. Diagnosing Sharing Anxiety

    Författare :Sigma Dolins; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ridehailing; sharing anxiety; shared autonomous vehicles; ridepooling; on-demand transport; qualitative methods; shared autonomous public transport; autonomous vehicles; public transport;

    Sammanfattning : Numerous studies indicate that the potential of autonomous vehicles (AVs) to reduce greenhouse gas emissions, reduce traffic congestion, and increase mobility access can only be fully realized through fleets of vehicles being used for shared rides, also known as dynamic ridepooling. This has the potential for transforming the public transport industry, as well as how transportation functions in urban and rural contexts. LÄS MER

  5. 4. Framework for holistic design of ferries focusing on lightweight ice going hulls

    Författare :Harsha Cheemakurthy; Karl Garme; Zuheir Barsoum; Magnus Burman; Jani Romanoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waterborne public transportation; commuter ferry; modular design; platform architecture; operational requirements; sustainable performance index; ice-hull interaction; lightweight ice-going hulls; composite; sandwich structure; ice impact model.; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Waterborne public transportation (WPT) is slowly increasing in importance as an active component of public transportation networks in cities. City planners are looking at WPT to overcome urban congestion and pollution. LÄS MER

  7. 5. Simulation based evaluation of flexible transit

    Författare :David Leffler; Erik Jenelius; Wilco Burghout; Oded Cats; Jan Persson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Transport authorities are faced with the challenge of making effective use of existing transportation infrastructure under increasing needs of transport accessibility, sustainability, and safety. The ongoing growth and adoption of shared mobility options, the anticipation of automated vehicles, and the increased availability of real-time data brought on with the developments of Intelligent Transport Systems, have all inspired many innovations in public transit design.
