  1. 1. Road Design for Future Maintenance Life-cycle Cost Analyses for Road Barriers

    Detta är en avhandling från Stockholm : KTH Royal Intstitute of Technology

    Författare :Hawzheen Karim; KTH.; Högskolan Dalarna.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Vägprojektering för minskade drift- och underhållskostnader; barrier collisions and barrier repair costs;

    Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER

  2. 2. Road Safety Development Index Theory, Philosophy and Practice

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ghazwan Al-Haji; Linköpings universitet.; Linköpings universitet.; [2007]

    Sammanfattning : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. LÄS MER

  3. 3. Improved road design for future maintenance analysis of road barrier repair costs

    Detta är en avhandling från Stockholm : KTH

    Författare :Hawzheen Karim; KTH.; Högskolan Dalarna.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Vägprojektering för minskade drift- och underhållskostnader; Keywords: highway maintenance; barrier repair cost;

    Sammanfattning : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. LÄS MER

  4. 4. Towards a Road Safety Development Index (RSDI) Development of an International Index to Measure Road Safety Performance

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ghazwan Al Haji; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; Road safety; RSDI; ASEAN; international comparisons; Human Development; Index; ranking; principal components; composite indicators; macro-performance indicators; macro-models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Aim. This study suggests a set of methodologies to combine different indicators of road safety into a single index. The RSDI is a simple and quick composite index, which may become a significant measurement in comparing, ranking and determining road safety levels in different countries and regions worldwide.

  5. 5. Safety Evaluation of Road Characteristics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sarbaz Najib Othman; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident data; FOT data; Overtaking maneuvers; Road safety; PC-Crash; Critical road parameters; Horizontal curves;

    Sammanfattning : Accidents are rare and widely distributed on the road network, which poses a challenge for road safety improvement. Traditional methods alone, such as accident analyses and experimental studies, do not explain all accident causation factors. LÄS MER
