    Nyckelord :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

  3. 2. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

    Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

    Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

    Sammanfattning : Investment planning is a decision-making process with specific characteristics. It is often seen as a rational quest for solutions that are in the public interest, and the dominant discourse tends to be technical and economic. LÄS MER

  5. 4. Swedish infrastructure policy and planning - conditions for sustainability

    Författare :Fredrik Pettersson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Infrastructure; policy; planning; sustainability;

    Sammanfattning : Sustainability has been on the agenda for decades. Yet it is not evident that the development we are witnessing can qualify as sustainable. Departing from an understanding of the adoption of sustainability as an on-going, unfinished process the thesis explores conditions for sustainability in Swedish transport infrastructure policy and planning.

  7. 5. 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
