1. 16. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

   Författare :Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
   Nyckelord :Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.

3. 17. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

   Författare :Gustav M Markkula; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

   Sammanfattning : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. LÄS MER

4. 18. Computational Verification Methods for Automotive Safety Systems

   Författare :Jonas Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Active Safety; Automotive; Verification; Augmented Reality; Performance Evaluation; Decision Making; Semi-Autonomous Vehicles;

   Sammanfattning : This thesis considers computational methods for analysis and verification of the class of automotive safety systems which support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents. Verification of these systems poses a major challenge, since system decisions are based on remote sensing of the surrounding environment and incorrect decisions are only rarely accepted by the driver.

5. 19. Towards Driver Adaptive Active Safety Systems

   Författare :Malin Sundbom; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent years, active safety systems have become a standard accessory in new cars and trucks. This thesis addresses one of the major flaws of most such systems: they act the same independently of who is operating the vehicle. LÄS MER
