Pathfinder 2016

Agent-based egress simulator:

  • SFPE mode (Nelson and Mower, 2002) / Steering mode (Amor et al., 2006)
  • Calibration: IMO (International Maritime Organization ) tests
  • Navigable Mesh
  • Behaviors: seek goals; waypoints; exits
  • Path planning: locally quickest
  • Door choice: minimizing traveling cost

Conclusions & Future Work

Conclusions:

  • Valuable Aid (Pathfinder)
  • Rapid prototyping
  • Results
  • Calibration is paramount
  • More examples and further scenarios are needed
