1. 21. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

   Författare :Azra Habibovic; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident prevention; Naturalistic observation; Causation analysis; Active safety system; Vulnerable road user VRU ; Driver behavior; Functional requirements; Statistical analysis; VRU behavior;

   Sammanfattning : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.

3. 22. Safety Evaluation of Road Characteristics

   Författare :Sarbaz Najib Othman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident data; FOT data; Overtaking maneuvers; Road safety; PC-Crash; Critical road parameters; Horizontal curves;

   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

4. 23. Modelling E-scooterist Braking and Steering for Collision Avoidance

   Författare :Tianyou Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bicycles; Cycling safety; Active safety; Bicycle kinematics; E-scooters; Micromobility;

   Sammanfattning : Introduction: In the last few years, new road safety issues have emerged with the growing popularity of novel micromobility vehicles (MMVs). The term ‘novel MMV’ includes, in addition to electrically assisted bicycles, electric kick scooters (e-scooters) and Segway balance scooters (Segways)—which are usually distinct in appearance and operation from traditional MMVs (conventional bicycles).

5. 24. Evaluating vehicle stability support systems by measuring, analyzing, and modeling driver behavior

   Författare :Gustav M Markkula; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver behavior; driver models; system evaluation; heavy trucks; driving simulators; active safety; electronic stability control;

   Sammanfattning : This thesis presents an investigation of near-accident behavior of truck drivers, with and without support from an electronic stability control (ESC) system. A critical scenario, involving both collision avoidance and vehicle stabilization on a low-friction surface, was studied in a driving simulator. LÄS MER

7. 25. Driver-centred Motion Control of Heavy Trucks

   Författare :Kristoffer K D Tagesson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; active safety; torque feedback; heavy trucks; motion coordination; steering by braking; oncoming collision; electronic stability control; active steering;

   Sammanfattning : Traffic accidents constitute one of the leading global causes of death. Deadly traffic accidents occur, even in countries that have implemented far-reaching countermeasures, at a rate that cannot be tolerated. Improved safety of heavy trucks is an important remedy, as these vehicles are involved in a large part of all fatal accidents. LÄS MER
