  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. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems

    Author : Andreas Tapani; Jan Lundgren; Haris N. Koutsopoulos; Linköpings universitet; []
    Keywords : Traffic; Micro; Simulation; Model; Car following; Rural road; Driver; Fatigue; Rumble strip; Adaptive cruise control; Active safety system; Safety; Evaluation; Overtaking; Traffic lane; Mathematical model; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. 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. Safety at Rail-Road Level Crossings

    Author : Mohammad Shahriari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver behaviour; risk analysis; traffic safety; rail road crossings; safety;

    Abstract : 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. READ MORE

  7. 5. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

    Author : Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

    Abstract : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.
