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

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
Motivation

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
Bio-inspired approach

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
Bio-inspired approach

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
Sociology theory

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
To-do list
