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

    Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; barrier collisions and barrier repair costs; Vägprojektering för minskade drift- och underhållskostnader;

    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

    Författare :Ghazwan Al-Haji; Kenneth Asp; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Transport; Road Traffic; Sustainability; Road safety; European research cooperation; Civil engineering and architecture; Research on Europe; Public health science; Statistics; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    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

    Författare :Hawzheen Karim; Ulf Isacsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.; Building engineering; Byggnadsteknik; Keywords: highway maintenance; barrier repair cost; Vägprojektering för minskade drift- och underhållskostnader;

    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. Safety at Rail-Road Level Crossings

    Författare :Mohammad Shahriari; Chalmers University of Technology; []
    Nyckelord :driver behaviour; risk analysis; traffic safety; rail road crossings; safety;

    Sammanfattning : Safety related to traffic at rail/road level crossings has long been a major issue for rail operators all over the world. Eliminating these level crossings entirely would be a desirable solution. However converting them into separate types is very expensive and not reasonable in many cases, e.g. LÄS MER

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

    Författare :Ghazwan Al Haji; Kenneth Asp; Linköpings universitet; []
    Nyckelord :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.
