  2. 1. Competition in Public Transport Essays on competitive tendering and open-access competition in Sweden

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas Vigren; KTH.; Statens väg- och transportforskningsinstitut.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transportvetenskap; Transport Science; Competition; Public Transport; Tendering; Procurement; Cost efficient; Bus; Railway; Open access competition; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Public transport; Contract; Tender; Economic efficiency; Location; Transport operator; Depot transp ; Impact study; Line transp ;

    Abstract : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. READ MORE

  4. 2. Costs in Swedish Public Transport An analysis of cost drivers and cost efficiency in public transport contracts

    Abstract : De senaste sju åren har de totala kostnaderna för att bedriva kollektivtrafik i Sverige ökat med över 30 procent i reala termer enligt siffror från myndigheten Trafikanalys. Jämförs en längre tidsperiod hittas samma mönster. READ MORE

  5. 3. MEILI Multiple Day Travel Behaviour Data Collection, Automation and Analysis

    University dissertation from KTH Royal Institute of Technology

    Author : Adrian Corneliu Prelipcean; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multiple day travel diary collection; trajectory segmentation; travel mode destination and purpose inference; travel diary collection system comparison; travel pattern stability and variability over time; Transportvetenskap; Transport Science; Datalogi; Computer Science; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Researchers' pursuit for the better understanding of the dynamics of travel and travel behaviour led to a constant advance in data collection methods. One such data collection method, the travel diary, is a common proxy for travel behaviour and its use has a long history in the transportation research community. READ MORE

  6. 4. Improving Performance in Heterogeneous Networks: A Transport Layer Centered Approach

    University dissertation from KTH Royal Institute of Technology

    Author : Johan Garcia; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2005]

    Abstract : It has been argued that for the management of complex issues such as sustainability, which transcend traditional policy sectors and require coordination between several different interests and actors, policymaking depends upon collaboration and integration processes between different sectors and tiers of government. The overall aim of this thesis is therefore to study how and why (or why not) policy integration processes are being developed in regional policymaking and what this means for the achievement of sustainable transport.
