Title: Bioinspired crowd evasion behavior


1
Bio-inspired crowd evasion behavior
  • Sang Woo Lee

2
Content
  • Project Outline
  • Motivation
  • Bio-inspired approaches
  • Sociology theory
  • To-do list

3
Project Outline
  • Objective
  • Simulating plausible crowd evasion behavior
    pattern
  • Method Outline
  • Adapt biological model
  • Integrate sociology theory
  • Evaluate with real human data

4
Motivation
  • Many crowd evasion patterns in modern society
  • Evacuation from building
  • Terrorist attack for crowd
  • Riot chased by police
  • Few crowd evasion pattern research
  • Helbing
  • Evacuation induced by panic
  • Used social force model
  • Zeeshan
  • Suicide bomber attack
  • Focused on damage minimization
  • Simple simulation model

5
Bio-inspired approach
  • Predator-pray in biology
  • One of most important research for biologist
  • Evasion is oriented from predator evasion
  • Even human is not exception
  • Immediate danger make no time to think
  • In high level perspective, biology model should
    match human evasion behavior
  • In emergency, individuals start pushing and
    physical interaction

6
Bio-inspired approach
  • Good model for fish school evasion
  • Simulate all the observed evasion pattern
  • Much easier to get more data and control
  • Much easier to evaluation

7
Sociology theory
  • Sociology theory
  • Distance danger makes people think
  • Can react with various enviroment/communicate
    information
  • Make social behavior (Grouping, communicate,
    influence)
  • Social Impact Theory Latane
  • Human behavior and attributes change function
    model
  • Strength, immediacy, number
  • Other theories

8
To-do list
  • Integrate fish collective evasion behavior
  • Integrate sociology terms for more convincing and
    realistic behavior
  • Tuning with real human group evasion behavior
  • Need real crowd data
  • Generate realistic crowd animation
  • Find some good evaluation method for crowd
    behavior
  • Might be future work
