1. 11. Barns säkra tillgänglighet till skolan

   Författare :Mats Gummesson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; bicyclist; Accessibility; children; traffic safety; school road; pedestrian;

   Sammanfattning : Children are an exposed group in traffic as unprotected road-users. The history of traffic education and how children were looked upon in steering documents of traffic planning shows how the view of children and the traffic system from authorities and organizations have changed over time.

3. 12. Environmental and domestic risk factors for respiratory symptoms in Nicaraguan children

   Författare :Danilo Hernandez; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; * wheeze* Child labor* asthma* allergy* aeroallergens* lung volumes* waste-picking* particles* wood-smoke* burning of solid waste;

   Sammanfattning : BackgroundRespiratory diseases are the most common cause for seeing a doctor in Nicaragua, and the second most common cause of death in children. An air monitoring program in the capital city, Managua, has shown high levels of air pollution, especially small particles. LÄS MER

4. 13. Link and effect model for performance improvement of railway infrastructure

   Författare :Christer Stenström; Antti Salonen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Railway traffic has increased over the last decade and it is believed to increase further with transportation shifting from road to rail, due to rising energy costs and the demand to reduce emissions. To manage railway infrastructure assets effectively against agreed-upon and set objectives, performance must be measured and monitored. LÄS MER

5. 14. On Control Strategy and Safety Verification of Automated Vehicles

   Författare :Roozbeh Kianfar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Over the last few decades, congested traffic network have become a serious problem in many countries. Congestions result in time losses, increase of fuel consumption, increase of CO2 emissions and also raise the risk of accidents. LÄS MER

7. 15. Analysis of Sensing Systems for the Detection of Pedestrian Impacts

   Författare :Sunan Huang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing system; pedestrian safety; accident investigation; statistical simulation; contact sensor; FE simulation;

   Sammanfattning : In order to reduce pedestrian casualties in vehicle traffic accidents, safety countermeasures, for example the active hood system and external airbag system, have been proposed to protect pedestrians in vehicle collisions. Such a protection system must consist of a sensing system to detect the pedestrian impact and/or the potential impact. LÄS MER
