  4. 28. Novel Algorithms for Optimal Transport via Splitting Methods

    Författare :Jacob Lindbäck; Mikael Johansson; Jérôme Malick; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal transport; splitting methods; Optimeringslära och systemteori; Optimization and Systems Theory;

    Sammanfattning : This thesis studies how the Douglas–Rachford splitting technique can be leveraged for scalable computational optimal transport (OT). By carefully splitting the problem, we derive an algorithm with several advantages. LÄS MER

  5. 29. 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

  7. 30. Exploring Support Infrastructures for Freight Transport Operations

    Författare :Andreas Hagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Intelligent Transport Systems; Infrastructure; Information Systems; Transportation;

    Sammanfattning : Previous publications on freight transport operations have outlined the need for increased effectiveness and better use of information in transport operations. A key to this is the availability and accessibility of information to improve management of transport operations. LÄS MER
