1. 11. The development of methods for detection and assessment of safety critical events in car driving

   Författare :Omar Bagdadi; Andras Varhelyi; Nicolas Saunier; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Near miss; Braking; Driving veh ; Driver; Behaviour; Tillbud; Bromsning; Fordonskörning; Förare; Beteende; Road: Road user behaviour; Road: Road user behaviour; Crash involvement; jerk; safety critical event;

   Sammanfattning : Improving our knowledge of drivers’ behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. LÄS MER

3. 12. A method for analysing the traffic process in a safety perspective

   Författare :Åse Svensson; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intermediate method; Accidents; pedestrian safety; safety hierarchy; severity; traffic conflicts; interaction; road user behaviour; traffic safety; traffic process; time to accidents; safety indicators; surrogate measures;

   Sammanfattning : The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. LÄS MER

4. 13. Parallel algorithms for real-time railway rescheduling

   Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Mats Brorsson; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In railway traffic systems, it is essential to achieve a high punctuality to satisfy the goals of the involved stakeholders. Thus, whenever disturbances occur, it is important to effectively reschedule trains while considering the perspectives of various stakeholders. LÄS MER

7. 15. A Holistic Safety Benefit Assessment Framework for Heavy Goods Vehicles

   Författare :Ron Schindler; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy goods vehicle; Bayesian methods; Safety benefit assessment; crash data analysis; driver behaviour modelling;

   Sammanfattning : In 2019, more than one million crashes occurred on European roads, resulting in almost 23,000 traffic fatalities. Although heavy goods vehicles (HGVs) were only involved in 4.4% of these crashes, their proportion in crashes with fatal outcomes was almost three times larger. LÄS MER
