  1. 1. Traffic safety analysis by surrogate measures:an extreme value approach

    University essay from Lunds universitet/Matematisk statistik

    Author : Heidi Mach; [2022]
    Keywords : Mathematics and Statistics;

    Abstract : Road safety analyses are required for the prevention of road accident fatalities. In Europe, the ambition is "Vision Zero". Data that was used is collected by the research group Transport and Roads which is part of Department of Technology and Society at LTH, Lund University. READ MORE

  3. 2. Analysis and Simulation Study of Stochastic Time-To-Collision as a Severity Measure in Traffic Security

    University essay from Lunds universitet/Matematisk statistik

    Author : Per Niklas Benzler Waaler; [2020]
    Keywords : time; collision; ttc; stochastic; probability; transform; transformation; traffic; data; under; estimation; post; encroachment; mixture; distribution; simulation; study; encounter; conflict; trajectory; prediction; road; user; safety; severity; surrogate; measure; Mathematics and Statistics;

    Abstract : Traffic accidents are extremely rare, creating the need for surrogate methods for safety analysis that makes efficient use of the information provided by traffic conflicts, which also are limited in availability. The severity measure time-to-collision (TTC) in combination with extreme value theory have so far been one of the primary measures used to infer traffic safety levels, but it relies on unrealistic assumptions that results in severity measures that do not always agree well with observed danger.

  4. 3. An Extreme Value Approach to Road Safety Analysis

    University essay from Lunds universitet/Matematisk statistik

    Author : Johanna Lägnert; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : In this thesis we study the feasibility of applying extreme value theory to data regarding road safety. In particular, we propose a model for assessing the risk of collision and near collision using extreme value theory. READ MORE

  5. 4. A Computational Analysis of Driving Variations in a Distributed Simulated Driving Environment

    University essay from Institutionen för datavetenskap

    Author : Ansar-Ul-Haque Yasar; Adeel Jameel; [2007]
    Keywords : Simulators; Driving; Computational Analysis; Distributed; Driving Variations;

    Abstract : This Master thesis report is the research conducted at the Linköping University (LiU) in the Cognitive Engineering group. This report describes and discusses the possible driving variations at T-intersections. In this study we tested how voice based command (GPS) system and traffic lights did influence the driving behavior. READ MORE
