  1. 1. Trängsel i välfärdsstaten : Expertis, politik och rumslig planering i 1960- och 1970-talets Sverige

    Författare :Katarina Nordström; Margaret Hunt; Jenny Beckman; Jenny Andersson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Fysisk riksplanering; land-use; knowledge production; spatial planning; co-production; regional development; 1960s; 1970s; Historia; History;

    Sammanfattning : This dissertation is concerned with knowledge production and governance of land-use. Its main focus is the development of the National Land-use Plan (fysisk riksplanering) in Sweden between 1965 and 1979. LÄS MER

  3. 2. Applying Data Analytics to Freight Train Delays in Shunting Yards

    Författare :Niloofar Minbashi; Markus Bohlin; Behzad Kordnejad; Carl-William Palmqvist; C. Tyler Dick; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shunting yards; delay prediction; congestion; delay probability distributions; temporal delay distributions; Rangergodsbangårdarna; förseningsprediktion; trängsel; fördröjning av sannolikhetsdistributioner; tidsfördröjningsdistributioner; Transportsystem; Transport Systems;

    Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

  4. 3. Public transport demand and supply management under uneven passenger distributions

    Författare :Soumela Peftitsi; Erik Jenelius; Oded Cats; Achille Fonzone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; public transport; uneven passenger distribution; transit assignment model; travel behavior; control measures; crowding information; skip-stop; Transportsystem; Transport Systems;

    Sammanfattning : Overcrowding in public transport (also known as public transportation, public transit, or transit) systems due to increased travel mobility has become a major problem for public transport operators. Overcrowded transit stations and vehicles are connected to travel time variability and greater discomfort for the passengers. LÄS MER

  5. 4. Simulation and Evaluation of Urban Rail On-board Crowding

    Författare :Soumela Peftitsi; Erik Jenelius; Oded Cats; Andreas Tapani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : As travel demand grows in many metropolitan areas, overcrowding in public transport systems has become a major issue. Crowding distribution can be highly uneven over station platforms and multi-car transit vehicles. This implies that cars are not equally utilized and thus, passengers perceive on-board crowding higher. LÄS MER

  7. 5. Congestion Effects in Transport Modelling and Forecasting

    Författare :Jens West; Maria Börjesson; Carlo Giamoco Prato; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Transport investments and policies are increasingly turned towards dealing with transport congestion rather than with shortening the potential free flow travel time. However, appraisal methodologies for projects meant to reduce congestion are relatively less well developed compared to methodologies for projects aiming to reduce travel times. LÄS MER
