  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

  4. 2. 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

  5. 3. Design for Perception - A human-centric approach to the design of driving automation systems based on the driver’s perception

    Author : Fjolle Novakazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; design method; human-centric design; human factors.; mental model; driving automation; cognitive engineering; understanding; empirical research; design tool; perception; levels of automation; mixed-methods research;

    Abstract : The automotive industry is rapidly developing driving automation systems (DAS) with the aim of supporting drivers by means of the automation of longitudinal and lateral vehicle control. As vehicle complexity increases and update-over-the-air features are enabling continuous development of vehicle software and functionality, the driver’s understanding of their responsibility and their vehicle’s capabilities and limitations is becoming significantly more important.

  6. 4. Fire safety design of road tunnels

    Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
    Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE
