2. 1. 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.

4. 2. Injuries among the elderly : study of fatal and non-fatal injury events

   Author : Harmeet Sjögren; Ulf Björnstig; Anders Eriksson; Pat Waller; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elderly; injury; prevention; traffic; home; fall; crash; disease; bicyclist; pedestrian; cost; vehicle;

   Abstract : In view of the expected increase in the proportion of elderly in the population in most western countries, we studied injuries among the elderly (>60 years) by investigating hospital-treated injuries in inpatients and outpatients, and fatal injuries.One-year Hospital Injury Data - Even though the elderly made up only 15% of the injured in one year, they accounted for 42% of the total cost of trauma medical care, showing that injuries among the elderly place a disproportional burden on the health care system.

5. 3. Determination of Volatile Hydrocarbons in Urban Air

   Author : Lars Löfgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; arenes; hydrocarbons; environment; alkenes; motor traffic; photochemical oxidant formation;

   Abstract : In the complex hydrocarbon mixture in urban air, the alkenes and arenes are of particular interest with respect to impact on health and environment. Knowledge of hydrocarbon concentrations in urban air is essential for the assessment and prevention of health hazards and photochemical oxidant formation. READ MORE

6. 4. Using life cycle assessment to support the development of electrified road vehicles. Component data models, methodology recommendations and technology advice for minimizing environmental impact

   Author : Anders Nordelöf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverter; magnet; LCI; electrical machine; stepwise improvements; electric vehicle; LCA; inventory data; motor; critical review; scalable model;

   Abstract : The anthropogenic pressure on the Earth system already overshoots safe limits for climate change, so there is an urgent need to drastically reduce greenhouse gas emissions caused by transportation. Electric propulsion technology is a promising solution that can decouple fossil fuel use from road vehicle traffic. READ MORE

7. 5. Winter Road Conditions and Traffic Accidents in Sweden and UK - Present and Future Climate Scenarios

   Author : Anna K Andersson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Winter road condition; Slipperiness; Traffic accident; Winter road maintenance; Climate change;

   Abstract : This thesis investigates the distribution of slippery roads in Sweden and the UK for the present climate and how this may be affected by climate change for the rest of the century. It also addresses future scenarios for traffic accidents and winter road maintenance. READ MORE
