  1. 1. Integrated pedestrian safety assessment methodology

    Författare :Nils Lübbe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; driver behavior; comfort zone boundary; integrated safety; pedestrian; Forward Collision Warning; False Positive;

    Sammanfattning : Pedestrian fatalities and injuries are a concern in many regions. Passive safety assessment is well established, and additional active safety assessment has recently emerged. However, assessment methods reflecting on the interaction between active and passive safety do not exist in regulatory or consumer testing. LÄS MER

  3. 2. 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. 3. Integrated Pedestrian Safety Assessment: A Method to Evaluate Combinations of Active and Passive Safety

    Författare :Nils Lübbe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AEB; assessment; pedestrian; comfort boundary; driver behaviour; False Positive; integrated safety; airbag; FCW; reaction time;

    Sammanfattning : Pedestrian road casualties are a major concern in many countries. Vehicle safety systems attempt to reduce casualties, and the accurate assessment of such systems is therefore essential. Passive safety assessment is well established, and additional active safety assessment has recently emerged. LÄS MER

  5. 4. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

    Författare :Lars Ekman; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

    Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER

  7. 5. 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
