  1. 1. Utmaningar vid överlämning av anläggningsdata från projekt till förvaltning : En fallstudie på Trafikverket

    Kandidat-uppsats, Högskolan Dalarna/Informatik

    Författare :Nathalie Sundqvist; Malin Gustafsson; [2023]
    Nyckelord :Handöver; management; rail; pröject; facility data; BIM; gap analysis; Överlamning; förvaltning; jarnvag; pröjekt; anlaggningsdata; BIM; gapanalys;

    Sammanfattning : Bakgrund: Att hitta effektiva sätt att hantera överlämningar är enligt tidigare studier fortsatt av vikt. Det finns omfattande forskning om projektmetoder, trots det har inte lika mycket uppmärksamhet riktats mot själva överlämningsprocessen till interna mottagare. LÄS MER

  3. 2. A process to assess fossil-free transport transition pathways and develop a sustainability roadmap for transport purchasers

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Lauren Brach; [2023]
    Nyckelord :Roadmap; corporate carbon strategy; decarbonisation; transportation; fossil-free; Earth and Environmental Sciences;

    Sammanfattning : Most (93%) of the greenhouse gas emissions in the transport sector come from road traffic in Sweden which includes passenger and freight transport activity (Trafikverket, 2022). The aim of this thesis was to understand pathways that transport purchasers can pursue to reach the fossil-free transportation goals from manufacturing plant to customer and to develop a process for assessing a market and developing a roadmap for achieving fossil-free transportation.

  4. 3. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Moa Nolinder; [2023]
    Nyckelord :;

    Sammanfattning : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. LÄS MER

  5. 4. Estimating the load weight of freight trains using machine learning

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

    Författare :Erik Kongpachith; [2023]
    Nyckelord :Railway freight Transport; Rail Vehicle Weighing; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Machine Learning; Regression; Polynomial Regression; Regression Trees; Random Forest Regression; Support Vector Regression; Järnvägsgods transport; Vägning av järnvägsfordon; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Maskininlärning; Regression; Polynom Regression; Regressionsträd; Random Forest Regression; Support Vector Regression;

    Sammanfattning : Accurate estimation of the load weight of freight trains is crucial for ensuring safe, efficient and sustainable rail freight transports. Traditional methods for estimating load weight often suffer from limitations in accuracy and efficiency. LÄS MER

  7. 5. Application of formal verification and validation on modern multi-functional signalling system

    Master-uppsats, KTH/Transportplanering

    Författare :Shamsul Arefin; [2022]
    Nyckelord :;

    Sammanfattning : Demand for rail transport is increasing day by day. Rail is popular in public transport due to punctuality, regularity, and safety. However, we hear daily that rail traffic still has many problems to solve about incidents, near misses, and signal errors. LÄS MER
