Using Case Study Data to Validate 3D Agent-based Pedestrian Simulation Tool for Building Egress Modeling

MassMotion is an agent-based pedestrian simulation tool which employs 3D environments and behavioral profiles to analyze pedestrian movements and route choice. This paper describes how observed evacuation drills were used to validate MassMotion for tower building egress modeling. Validation metrics include modeled evacuation time, journey times, speeds, flow rates, and behavioral observations. The results indicate that MassMotion is a suitable application for tower building egress modeling, producing total evacuation times between 1% and 10% of observed times.
