  1. 1. The impact of social influence on pre-evacuation behavior - An eye tracking analysis on information gathering during pre-evacuation behavior, comparing normative and informational social influence

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Rebecca Rostedt; Sofie Andersson; [2019]
    Nyckelord :Social influence; informational social influence; normative social influence; pre-evacuation; evacuation; eye-tracking; Technology and Engineering;

    Sammanfattning : This study explores social influence within the pre-evacuation phase, which includes a literature review followed by experiments. The study is based on experiments by Latané and Darley (1968) but altered, here using eye tracking to examine if people who are alone use their gaze in the same way as people in a group, when collecting information in the pre-evacuation phase.

  2. 2. Crowd evacuation in high-density scenarios

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Ines Cilenti; [2019]
    Nyckelord :Crowd evacuation; high-density; crowd pressure; video analysis; bottleneck; outdoor event; local density.; Technology and Engineering;

    Sammanfattning : Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. LÄS MER

  3. 3. Testing the International Standards Organization Verification and Validation protocol for evacuation simulations-An application to the FDS+Evac model

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Yalong Wu; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Nowadays, many evacuation models exist in the market, and new models are continuously released with new features. How to assess the usability and reliability of model results becomes an issue for both developers and users. Therefore, verification and validation (V&V) protocols were introduced in the assessment process of evacuation models. LÄS MER

  4. 4. Improving Flow Rate with Funnel-shaped Space Design using Crowd Simulation for Large Crowds

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anna Jargård; Robert Kindwall; [2019]
    Nyckelord :;

    Sammanfattning : Crowd simulation is a technique used to model real people as agents in a computer-generated environment. Generating simulated crowds can help the research process of testing with agents in multiple scenarios without having to use real people. LÄS MER

  5. 5. Täta hus : en litterturstudie om lufttäthet samt en tolkning av samband mellan lufttäthet och brandtryck

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Emelie Lindvall; [2019]
    Nyckelord :Airtightness; fire pressure; FDS; leakage; evacuation; Lufttäthet; brandtryck; FDS; läckage; utrymning;

    Sammanfattning : Under 60- och 70-talet var tillväxten i Sverige god. Befolkningsmängden ökade och många valde att flytta från landsbygd till större städer för arbete. Omfattande bostadsbrist ledde till att Miljonprogrammetinfördes – en miljon bostäder skulle byggas på väldigt kort tid. LÄS MER
