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

    Author : Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : 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. READ MORE

    Abstract : Since ancient times, roads have tied people and cultures together. Roads have been createdwith the aim of facilitating trade and cultural exchange among different regions in the world. READ MORE

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

    Author : Hawzheen Karim; Ulf Isacsson; KTH; []
    Keywords : 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; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : 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. READ MORE

  6. 4. Towards Smart Maintenance : Machine-Learning Based Prediction of Retroreflectivity and Color of Road Traffic Signs

    Author : Roxan Saleh; Hasan Fleyeh; Moudud Alam; Arend Hintze; Darko Babic; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road traffic signs; Retroreflectivity; Chromaticity; Maintenance; Predictive models; classification; Survival analysis; Kaplan Estimator; Machine Learning;

    Abstract : Proper maintenance of road traffic signs is vital for safety, as their low visibility can cause accidents and fatalities. Many countries, including Sweden, lack a systematic approach for replacing signs due to the risky, costly, and complex methods needed to measure their color and retroreflectivity. READ MORE

  7. 5. On the establishment of a data-driven approach to gravel road maintenance

    Author : Keegan Mbiyana; Mirka Kans; Lars Håkansson; Jaime Campos; Ramin Karim; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; condition assessment; conceptual modelling; condition classification; data acquisition; data-driven methods; field experiment; literature review; maintenance; visual assessment; Maskinteknik; Mechanical Engineering;

    Abstract : Gravel roads are essential for economic development as they facilitate the movement of people, transportation of goods and services, and promote cultural and social development. They typically connect sparsely populated rural areas to urban centres, providing essential access for residents and entrepreneurs. READ MORE
