1. Safety Evaluation of Road Characteristics
Sammanfattning : Accidents are rare and widely distributed on the road network, which poses a challenge for road safety improvement. Traditional methods alone, such as accident analyses and experimental studies, do not explain all accident causation factors. LÄS MER
2. The Road From Damascus : New Arrival Immigrant Families and The Swedish Preschool
Sammanfattning : The overall aim of this doctoral thesis is to examine the perceptions that new arrival immigrant families have of Swedish preschool, and the perceptions of these families as expressed by the Swedish state preschool political discourse over the last fifty-year period. For this purpose, the study uses critical discourse analysis, as proposed by Norman Fairclough. LÄS MER
3. Influence Of Road Feature Variables On Accident Rate
Sammanfattning : The main objective of this traffic safety investigation was to find critical road parameters affecting accident rate (AR). The secondary objective was to analyze any identified risk factors from a vehicle dynamics perspective. LÄS MER
4. Analysis of Retroreflection and other Properties of Road Signs
Sammanfattning : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.

5. Using life cycle assessment to support the development of electrified road vehicles. Component data models, methodology recommendations and technology advice for minimizing environmental impact
Sammanfattning : 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. LÄS MER
