  1. 6. 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 : Transportation and transportation infrastructure are major contributors to global emissions. Even though most of these emissions can be attributed to fuel consumption of vehicles, some of it is due to pavement construction and maintenance. LÄS MER

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

    Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    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

  4. 9. An infrastructure of freedom : Atlanta, race, and the struggle over public transportation in the capitalist city

    Författare :Marcus Mohall; Don Mitchell; David Jansson; Theresa Enright; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public transportation; transit; transit struggles; transportation; planning; mobility; politics of mobility; transportation politics; infrastructure; capitalism; race; USA; US South; Atlanta; Social and Economic Geography; Kulturgeografi;

    Sammanfattning : This thesis provides a multiscalar analysis of the production and struggle over the Metropolitan Atlanta Rapid Transit Authority (MARTA), the main transit system in metro Atlanta. It examines how the actions and visions of the state, capital, and transportation activists intersect to structure how and to what extent transit systems can be organized to realize their distinctive potential to allow urban residents to meet their basic mobility needs.
