WHAT IS IT?

This model simulates emergency response behavior using Protection Motivation Theory (PMT) and Risk Information Seeking and Processing (RISP) frameworks.

Agent Types: - Red: Immediate Sharers (17.7%) - Blue: Cautious Validators (29.1%) - Green: Social Followers (27.6%) - Yellow: Independent Rational (25.6%)

HOW IT WORKS

Key Behaviors: • Information sharing and verification • Social influence and contagion • Panic vs rational evacuation decisions • Network effects on information flow

HOW TO USE IT

USAGE INSTRUCTIONS:

  1. Adjust sliders for population and timing
  2. Click 'Setup' to initialize model
  3. Click 'Test Setup' to verify distributions
  4. Click 'Go' to run simulation
  5. Use 'Update Display' to see state changes
  6. Try 'Show Network' to visualize connections
  7. Run 'Test Rules' to validate behaviors
  8. Use 'Run Experiment' for full analysis

THINGS TO NOTICE

  1. Click "Setup" - should see 150 colored agents
  2. Click "Test Setup" - check console for correct percentages
  3. Click "Go Once" a few times - watch monitors change
  4. Click "Show Network" - see social connections
  5. Let emergency start (tick 10) - watch evacuation begin
  6. Observe plots updating in real-time

THINGS TO TRY

(suggested things for the user to try to do (move sliders, switches, etc.) with the model)

EXTENDING THE MODEL

(suggested things to add or change in the Code tab to make the model more complicated, detailed, accurate, etc.)

NETLOGO FEATURES

(interesting or unusual features of NetLogo that the model uses, particularly in the Code tab; or where workarounds were needed for missing features)

RELATED MODELS
