Pedestrian Evacuation Planning

Advanced crowd modeling for safer emergency egress

Why Pedestrian Evacuation Planning?

Critical for safety during emergencies in crowded spaces

Emergency situations like earthquakes, fires, or security threats create dangerous crowd movements that can lead to injuries or fatalities. Effective evacuation planning is essential to guide people to safety quickly and efficiently.

Proper evacuation planning can reduce evacuation times by up to 40% and prevent crowd crushes in emergency scenarios.

Key Challenges Addressed:

  • Bottleneck Identification: Locating potential choke points in pedestrian flow
  • Egress Optimization: Calculating optimal evacuation routes and timing
  • Facility Assessment: Evaluating structural capacity for emergency loads
  • Wayfinding Solutions: Designing effective signage and guidance systems
