  1. 16. Impact of Anomalies in Simulated Crowds

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Edström Kawaji; Johan Ribom; [2018]
    Keywords : ;

    Abstract : Virtual simulations of crowds are useful for many different fields of research and entertainment, such as simulations of evacuation scenarios or in video games that use large amounts of moving agents. This study examines if the noticeability of movement anomalies are dependent on their location on the screen and the density of the virtual crowd. READ MORE

  3. 17. Crowd Simulation Using Flow Tiles

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Leo Enge; Felix Liu; [2018]
    Keywords : ;

    Abstract : Crowd simulations are being used in an increasing number of different applications, like evacuation scenarios, video games and movie special effects This creates a demand for crowd simulators that are simple to use and accessible to users of varying backgrounds. We will study the flow tile method proposed by Chenney [1], which provides an intuitive way of interactively designing divergence free velocity fields for various applications. READ MORE

  4. 18. Evacuation with Obstacles in Real-Time using Crowd Simulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tom Axblad; Alvaro Ortega Gonzalez; [2018]
    Keywords : ;

    Abstract : Exits with obstacles facilitate evacuations under specific circumstances. In order to quickly and efficiently find these circumstances, crowd simulations can be used. In this study, a particle based crowd simulation is used to find evacuation scenarios where obstacles facilitate evacuation. READ MORE

  5. 19. A Scoping Review for the Parameters of Crowd Movement

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Andreas Hansen; [2018]
    Keywords : Crowd movement; scoping review; evacuation; age; body projection area; bottlenecks; openings; culture; occupant density; emergency or non-emergency; emotional state; fatigue; fitness; gender; group size; headway; health status; height; lateral sway; personal space; social relations; stair gradient; step frequency; step size; vision; weight; Technology and Engineering;

    Abstract : Existing models which describe crowd movement are running out of time and are failing to take the change of people’s characteristics into account. The purpose of this study is to determine the “state-of- the-art” regarding the research within the field of crowd movement and identify parameters that influence crowd movement. READ MORE

  6. 20. A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Selenay Simsek; [2016]
    Keywords : Pedestrian movement; evacuation experiments; inter-person distance; fundamental diagram; Technology and Engineering;

    Abstract : A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device The quantitative characteristics of people movement that form the fundamental diagram have an important role in the field of Fire Safety Engineering regarding evacuation. The fundamental diagram indicates the relation between crowd speed and crowd density (or inter-person distance) or flow of crowd and crowd density. READ MORE
