1. 21. Machine Learning-Based Prediction Models and Threat Detection for Lane-Keeping Assistance

   Författare :John Dahl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; ADAS; Threat detection; Threat assessment;

   Sammanfattning : Traffic accidents have been an ongoing problem for over a century and many efforts have been made to improve traffic safety. Historically, the focus has been on passive safety with innovations, such as crumpling zones, three-point seat belts, and airbags, that aim to mitigate the impact of collisions. LÄS MER

3. 22. Traffic Situation Management for Driving Automation of Articulated Heavy Road Transports - From driver behaviour towards highway autopilot

   Författare :Peter Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; driving simulator; driving principles; driving automation; vehicle model; articulated heavy-vehicles; vehicle dynamics; long combination vehicles;

   Sammanfattning : In this thesis traffic situation management for driving automation of long combination vehicles is discussed. The automation targets high-speed driving in multiple-lane, one-way roads. Traffic situation predictions, traffic situation manoeuvres and driving principles are studied specifically. LÄS MER

4. 23. A dispatch procedure for traffic control of a fleet of remote-controlled automatic LHDS in underground hard rock mines : modelling approach is based on simulation

   Författare :Nikolaos Vagenas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Sammanfattning : A concept for automating Load-Haul-Dump (LHD) vehicles has stimulated considerable interest in the Swedish mining industry. In this concept, tramming and dumping operations of an LHD should be automatic. During loading, an operator from a control room fills the bucket of a vehicle via remote-control aided by a television system. LÄS MER

5. 24. Attraction Based Models of Collective Motion

   Författare :Daniel Strömbom; David J. T. Sumpter; Andreas Deutsch; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; flocking; swarming; self-propelled particles; alignment-free models; agent-based modelling; leaf-cutting ant traffic; sheep-sheepdog system; the Shepherding problem; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Animal groups often exhibit highly coordinated collective motion in a variety of situations. For example, bird flocks, schools of fish, a flock of sheep being herded by a dog and highly efficient traffic on an ant trail. LÄS MER

7. 25. Towards computational models for road-user interaction: Drivers overtaking pedestrians and cyclists

   Författare :Alexander Rasch; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active safety; vulnerable road users; cyclist safety; driver models; interaction models; overtaking; Euro NCAP; driver behavior; Pedestrian safety;

   Sammanfattning : Introduction: Crashes resulting from a failed interaction between drivers and vulnerable road users, such as pedestrians or cyclists, can lead to severe injuries or fatalities, especially after failed overtaking maneuvers on rural roads where designated refuge areas are often absent, and impact speeds high. This thesis contains two studies that shed light on driver interaction with either 1) a pedestrian or 2) a cyclist, and oncoming traffic while overtaking. LÄS MER
