  1. 1. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alexander Adolfsson; [2022]
    Nyckelord :Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

    Sammanfattning : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. LÄS MER

  3. 2. Integration of Open Data in Disaggregate Transport Modelling : A Case Study of Uppsala

    Master-uppsats, KTH/Transportplanering

    Författare :Iqbal Surahman; Gustav Wegner; [2022]
    Nyckelord :Agent-based; Disaggregate Transport Model; Open Data; OpenStreetMap; OSM; GTFS; Agentbaserad; Disaggregerad Transportmodell; OpenData; OpenStreetMap; OSM; GTFS;

    Sammanfattning : Transport models are key in predicting travel behaviour and planning transport systems. Transport models can be either aggregated or disaggregated. Disaggregation means that travel behaviour is represented on an individual level, which can be beneficial because it offers a higher detail level and reduces aggregation bias. LÄS MER

  4. 3. How to make the most of open data? A travel demand and supply model for regional bicycle paths

    Master-uppsats, KTH/Transport och systemanalys

    Författare :Laurent Cazor; [2021]
    Nyckelord :Planning Support System PSS ; Four-Step Model; Gravity Model; Distance-Decay function; Binary Logit Model; Level of Traffic Stress LTS ; Geographic Information System GIS ;

    Sammanfattning : Detta examensarbete syftar till att svara på ett av Trafikverket fastställt problem: en gemensam regional cykelplanerings process skulle göra dem billigare och mer jämförbara. De erbjuder för närvarande planerarna en modell som utvecklades av Kågeson 2007. LÄS MER

  5. 4. Validation of a Public Transport Model

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Yousef Aho; Johannes de Jong; [2020]
    Nyckelord :Model validation; transport model; public transport model; public transport system; route assignment; validation metrics; Modellvalidering; transportmodell; kollektivtrafikmodell; kollektivtrafiksystem; nätutläggning; valideringsmått;

    Sammanfattning : During 2018, the Public Transport Administration (Trafikförvaltningen) in the Stockholm region spent approximately 2.2 billion SEK on new infrastructure investments related to the public transport system, many of which were based on their public transport models. LÄS MER

  7. 5. Groundwater Flow and Transport Modelling of PFASs in Åkersberga

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Worada Boonraksasat; [2019]
    Nyckelord :Groundwater modelling; contaminant transport; Visual MODFLOW; MODPATH; MT3DMS; PFASs; AFFFs;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a group of man-made organic chemicals that have been commercially used since the 1950s in many consumer products, including impregnated textiles, impregnated paper, nonstick products (e.g., Teflon), cleaning agents, and in firefighting foams.
