1. 6. Energy Absorbing Material Concepts for Automotive Accident Injury Prevention

   Författare :Rickard Juntikka; KTH; []
   Nyckelord :Head impact; energy absorption; cellular materials; automotive; dynamic; pedestrian; interior; compression; shear; finite element analysis; optimisation;

   Sammanfattning : Although automotive safety has experienced a rapiddevelopment during the last decades, traffic related accidentsrank very high in many countries in terms of cause of death.Statistics show that the head is the body region mostfrequently injured in motor vehicle accidents and the primarycause of death is head injuries.

3. 7. 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

4. 8. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

   Författare :Lars Ekman; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

   Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER

5. 9. Development of traffic conflicts technique for different environments: A comparative study of pedestrian conflicts in Sweden and Jordan

   Författare :Lina Shbeeb; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perception of conflicts.; non-signalised junctions; signalised junctions; accident prediction; accident to conflict conversion factors; TA-speed graphs; conflict speed; time to accidents; conflict sub-grouping; severity index; threshold; relevant road-user; pedestrian conflict; Traffic safety; traffic conflict technique; Technological sciences; Teknik; Social sciences; Samhällsvetenskaper;

   Sammanfattning : This study is aimed at improving the current Swedish Traffic conflicts Technique [TCT] in relation to vehicle-pedestrian conflicts. The present definition of conflict severity appears to produce less severe conflicts than they might be, particularly if the relevant road user (RRU) is the pedestrian. LÄS MER

7. 10. 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.
