1. 21. Injuries are not accidents! : an emergency-department population-based epidemiological study of injuries with special reference to trauma recidivism hip fractures and geriatric falls

   Författare :Fredrik Röding; Ulrica Bergström; Marie Lindkvist; Jack Lysholm; Per Morberg; Olle Svensson; Sari Ponzer; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; injury; population; fractures; contusions; sprains; fall injuries; Orthopaedics; ortopedi;

   Sammanfattning : Injury is a major public health problem. In rich countries fall injures now kill more people than all other injury mechanisms together, because of global ageing and large-scale sustainable injury prevention programs for all other injury mechanisms but falls. LÄS MER

3. 22. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

   Författare :Yu-Hsing Huang; Erik Hollnagel; Pietro Carlo Cacciabue; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; Cognitive science; Kognitionsvetenskap;

   Sammanfattning : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. LÄS MER

4. 23. Analysis of Retroreflection and other Properties of Road Signs

   Författare :Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

   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. 24. Control of vehicle platoons and traffic dynamics : catch-up coordination and congestion dissipation

   Författare :Mladen Čičić; Karl H. Johansson; Daniel Work; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Congestion; Intelligent Transport Systems; Moving Bottlenecks; Platoon Coordination; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array ofnegative effects on the society, from wasted time and productivity to elevated air pollution and increased number of accidents. Classical traffic control methods have long been successfully employed to alleviate congestion, improving the traffic situation of many cities and highways. LÄS MER

7. 25. 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
