  1. 1. A Microdata Analysis Approach to Transport Infrastructure Maintenance

    Författare :Kristin Svenson; Lars Rönnegård; Karin Edvardsson; Nasir Gharaibeh; Högskolan Dalarna; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Transport Infrastructure Asset Management; Transport Infrastructure Maintenance; Statistical Modeling; Microdata Analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Mikrodataanalys; Microdata Analysis;

    Sammanfattning : Maintenance of transport infrastructure assets is widely advocated as the key in minimizing current and future costs of the transportation network. While effective maintenance decisions are often a result of engineering skills and practical knowledge, efficient decisions must also account for the net result over an asset's life-cycle. LÄS MER

  2. 2. Interaction Infrastructure : a Holistic Approach to Support Co-Modality for Freight

    Författare :Inger Gustafsson; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Logistics; Co-modality; Transport policy; Information;

    Sammanfattning : In this thesis I have illustrated how information is essential for the management of transport chains. I have explored the notion of transparency as well as its importance for transport chains. The conclusion drawn is that transparency does not mean that every player should know everything at all times. LÄS MER

  3. 3. Underneath Norrköping : An Urban Mine of Hibernating Infrastructure

    Författare :Björn Wallsten; Joakim Krook; Vanesa Castán Broto; Linköpings universitet; []
    Nyckelord :Urban mining; infrastructure; hibernating stocks; Material Flow Analysis; infrastructure studies; Norrköping;

    Sammanfattning : This study examines the subsurface infrastructure in the Swedish city of Norrköping from an urban mining perspective. Urban mining is a broadly defined term for different strategies that regard the built environment as a resource base for materials. LÄS MER

  4. 4. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

    Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

  5. 5. Modelling and evaluation of the effects of traffic safety measures Comparative analysis of driving assistance systems and road infrastructure

    Författare :Meng Lu; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vägtransportteknik; GRA; Road transport technology; grey relational analysis; driving assistance systems; traffic safety principle; quantitative causal chain; comparative analysis; QCC model; road infrastructure; road traffic safety;

    Sammanfattning : Improvement of road traffic safety is an important policy issue. Various categories of meas-ures are available to effectuate this. The thesis focuses on two categories: road infrastructure and driv-ing assistance systems. LÄS MER
