  1. 11. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

    Författare :Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

    Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER

    Sammanfattning : Pavement system plays an indispensable role in the socio-economic and sustainable development of every modern society. Yet, pavement construction and maintenance is also responsible for a significant fraction of the GHG emissions from the whole transport sector. LÄS MER

  4. 13. A Microdata Analysis Approach to Transport Infrastructure Maintenance

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

    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

  5. 14. Integrated Product Service Offerings for Rail and Road Infrastructure : Reviewing Applicability in Sweden

    Författare :Sofia Lingegård; Mattias Lindahl; Niclas Svensson; Daniel Brissaud; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Product Service Offerings; Product Service Systems; long-term contracts; risk; life-cycle perspective; resource-efficiency;

    Sammanfattning : This research aims to explore and propose a more effective management of rail and road infrastructure and the possibility of a more resource-efficient road and rail infrastructure by applying business models based on performance and a life-cycle perspective.There is a lack of efficiency in the Swedish rail and road infrastructure industries - at the same time as the availability of the rail tracks and roads is essential.

  7. 15. Management with the People : An Enabling Approach to Neighbourhood Road Infrastructure Management in Kampala City

    Författare :Ian Senkatuka; Örjan Svane; Barnabas Nawangwe; Wilbard Kombe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urbanisation; Developing Country; Infrastructure; Neighbourhood Road; Management; Community Participation; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : Rapid urbanization occurring in many developing countries coupled with the constraints they are facing, has affected road infrastructure service delivery by public authorities charged with managing them. In Kampala City’s mixed income neighbourhood areas that have a disparity between neighbourhood community members, inadequate neighbourhood road management by Kampala City Council who are charged with managing these roads has led to neighbourhood roads that are in a poor state of disrepair, and do not meet many of the needs of their users.
